Chapter 1
SLAU358B – September 2011 – Revised June 2012
Introduction
The MSP Gang Programmer is an MSP430 device programmer that can program up to eight identical
MSP430 flash or FRAM devices at the same time. The MSP Gang Programmer connects to a host PC
using a standard RS-232 or USB connection and provides flexible programming options that allow the
user to fully customize the process. A top-level view of the MSP Gang Programmer can be seen in
Figure 1-1.
The MSP Gang Programmer is not a gang programmer in the traditional sense, in that there are not eight
sockets provided to program target devices. Instead, the MSP Gang Programmer is designed to connect
to target devices in-circuit (that is, target devices are mounted in the final circuit or system). The MSP
Gang Programmer accesses target devices using connectors that use JTAG or Spy-Bi-Wire (SBW)
signals.
The MSP Gang Programmer is provided with an expansion board, called the Gang Splitter, that
implements the interconnections between the MSP Gang Programmer and multiple target devices. Eight
cables are provided that connect the expansion board to eight target devices (via JTAG or Spy-Bi-Wire
connectors).
Chapter 2 describes in detail how to use the MSP Gang Programmer to program target devices. Various
modes of operation are described, and they allow the user to choose the most convenient method of
programming. In addition, this chapter describes the various windows that are used to configure the
programming procedure for a specific target device.
Chapter 3 describes firmware commands that can be used to control the programming process at fine
granularity. Firmware commands can be received over an RS-232 or USB port and correspond to specific
actions that the programmer can perform. Take great care in using these commands, because they must
often be used in groups for proper behavior, and the order in which they are executed affects the result.
Chapter 4 describes Gang430.dll and MSP-GANG.dll, including the functions available through them.
Chapter 5 contains an I/O schematic that shows how signals from the MSP Gang Programmer can be
brought out to each of the target devices via an MSP430-standard JTAG or Spy-Bi-Wire connector. The
circuit can be easily modified to connect signals to the target device pins directly (via a socket) if a
traditional gang programmer setup is desired.

www.ti.com
Driver Installation
To install the required drivers:
1. Connect the MSP-GANG programmer to PC USB port. When the Windows Wizard starts then follow
instruction provided by wizard. When Wizard ask for the USB driver location then browse the D:
location where D: represents the CD-ROM location. Drivers are located in the main CD-ROM directory
location and also in the following directory:
C:\Program Files\Texas Instruments\MSP-GANG\Driver
2. If the RS-232 interface is used for communication with MSP-GANG, then the additional driver is not
required. Check in the Device Manager the COM-port number that should be used with communication
via RS-232.
1.3
Hardware Installation
To install the MSP Gang Programmer hardware:
1. Attach the expansion board (Gang Splitter) to the 100-pin connector on the MSP Gang Programmer.
The expansion board provides connectivity for up to eight targets using the included 14-pin cables. The
target MSP430 flash devices can be in standalone sockets or can be on an application's PCB. These
devices can be accessed via JTAG or Spy-Bi-Wire (SBW) signals.
2. Connect the MSP Gang Programmer hardware to a computer's USB port using a USB A-B cable.
The programmer can be fully supplied from the computer's USB port (5 V, 0.5 A). The programmer can
also be connected to a serial port (COM1 to COM255) using a 9-pin Sub-D connector, if the computer
does not have a USB port.
3. An external power supply is required to power the MSP Gang Programmer if it is not connected via
USB port or if the total current consumption of the programmed target devices exceeds 0.3 A.
NOTE: External Power Supply
If an external power supply is used then it must provide a voltage between 6 V and 10 V dc
and must be capable of providing a minimum current of 800 mA. The center post of the
power supply connector on the MSP Gang Programmer is the positive-voltage terminal. The
programmer indicates the status of the power supply connection by using system LEDs and
the LCD back light.
NOTE: Maximum Signal Path Length: 50 cm
The maximum length of a signal path between the 14-pin JTAG or SBW connector on the
Gang Splitter and the target device is 50 cm.
4. The MSP Gang Programmer can supply power at a specified voltage VCC to each target device
separately (pin 2 on each 14-pin JTAG or SBW cable). The maximum current for each target device is
programmable and can be 30 mA or 50 mA. If the higher current limit is selected (50 mA) and eight
target devices are connected, then the total current taken by all devices can reach up to 400 mA. In
this case, the MSP Gang Programmer must be supplied from an external power supply instead of from
the USB port. This is because the total current drawn from the USB port cannot exceed 0.5 A, and
150 mA are consumed by the MSP Gang Programmer itself, leaving 350 mA for the target devices.

CAUTION
When an external power supply is used to power target devices, it is important
to disconnect VCC (pin 2 on the JTAG or SBW connector) from the targets to
avoid power-supply conflicts that could potentially damage the MSP Gang
Programmer and the target devices.
When target devices are powered from an external power supply, the VCC from
the target device should be connected to Vextin (pin 4) on the JTAG or SBW
connectors. This voltage is used by the MSP Gang Programmer for sensing the
presence of an external power supply.
Also, the same voltage value that is used for powering the target device should
be set in the MSP Gang Programmer as the desired VCC level. This information
is mandatory to provide correct I/O levels for the TMS, TCK, TDI, TDO, and
RST signals. If the wrong VCC is provided, then the I/O levels between the
programmer and target devices can be too low or too high, and communication
can become unreliable.
5. The MSP Gang Programmer can be supplied from an external power supply connected to the dc
connector or via a gang splitter (not populated J10 connector). Because the J10 and dc connectors are
connected in parallel, make sure that only one connector provides an external power supply to the
MSP Gang Programmer.

Operation
This chapter describes how to use the MSP Gang Programmer to program target devices. Various modes
of operation, which allow the user to choose the most convenient method of programming, are described.
In addition, this chapter describes the various windows that are used to configure the programming
procedure for a specific target device. The explanations in this chapter assume that the user has properly
installed the MSP Gang Programmer hardware and software as described in Chapter 1.
2.1
Programming MSP430 Flash Devices Using the MSP Gang Programmer
The MSP Gang Programmer is capable of quickly and reliably programming MSP430 flash devices using
an RS-232 or USB interface. There are four ways to use the programmer to achieve this task and these
include:
• Interactive
• From Image
• From Script
• Standalone
The Interactive mode is selected by default, and is the easiest to get started with, because it requires the
least amount of preparation. After the user has mastered the Interactive mode it can be used to create
images and script files, which can then be used with the From Image and From Script modes,
respectively. Images and scripts are ready-to-go setups than can run with minimal user input. They are
very useful for repetitive programming, for example in a production environment, because they ensure
consistency (because of the re-use of images or scripts, we highly encourage the user to thoroughly test
their images or scripts for correctness before committing them to production). The MSP Gang Programmer
can also be run in Standalone mode to program target devices without a PC. To do this, first create an
image to use for programming, and then save it to internal memory of the MSP Gang Programmer.
Creating images is described in Section 2.1.6.
The following sections describe how to use these modes of operation.

2.1.1 Programming Using Interactive Mode
Use the following sequence to start the MSP Gang Programmer GUI and program MSP430 Flash Devices
using the Interactive Mode:
1. Click on the MSP Gang Programmer icon located in the program group specified during installation.
Figure 2-1 shows the MSP Gang Programmer GUI in the Interactive Mode (see top left corner). This
window is used to select the target processor, code file used for programming, power supply options,
communication interface, and more. This window also shows the result of programming and any errors,
if they occur.
NOTE: This figure show the Interactive Mode (see the Mode section in the top left corner). The user can select
the target processor, source file for programming, power supply options, communication interface, and more.
This window also shows the result of programming and any errors, if they occur.
Figure 2-1. Main MSP Gang Programmer Dialog GUI, Interactive Mode
2. Select a target device using the MCU Type menu (select MCU group and then desired MCU type).
3. Select the code file to be programmed into the device(s) using the Open Code File button or pulldown
menu: File→Open Code File. The formats supported for the code file are TI (.txt) and Intel (.hex) and
Motorola (.s19, .s28, .s37). Code size and checksum appear on the right side.
4. Optionally add another code file to be programmed into the device(s) using the Append Code File
button (check the box on the left to enable this option). This feature is useful for updating BSL firmware
in 5xx or 6xx MCUs. The two code files are combined together to create one final code file. If a conflict
is detected, a warning appears; however, if programming proceeds without changes the second code

file overwrites the conflict area. Code size and checksum appear on the right side.
5. Some processors (for example, the MSP430FR57xx) provide a method of disabling JTAG by
programming a password to flash memory. The password should be specified as data to be
programmed starting at 0xFF80 and up to 0xFFFF (where 0xFF80 must be 0xAAAA, 0xFF82 must be
the size of the password in words, and 0xFF88-0xFFFF contains the password). The code file must
contain password contents if you intend to lock JTAG using the password feature after programming. If
the MCU is already locked using a previously programmed code file, then you must provide the
password section (or entire old code file) using the Open Password File button if and only if the
password section is different. Functionally, if the MCU is locked by password, the code file’s password
section is first used to attempt to unlock the MCU. If that fails, then the password file’s contents are
used to attempt to unlock the MCU. If both attempts fail, the MCU remains locked and JTAG access
fails. Password file contents are not used to program the MCU.
6. In the Target power group, select the desired VCC voltage and select if the target is supplied from the
MSP Gang Programmer or from an external power supply. If targets are supplied by the programmer,
then select the maximum current used by each target, 30 mA or 50 mA.
7. In the Results group, select desired target devices to be programmed. After programming has
concluded, a green checkmark or lights appear for successful operations for each target.
8. In the Interface selector, choose the desired interface (JTAG or Spy-Bi-Wire) and communication
speed (fast, medium, or slow).
9. In the Memory Options dialog (pulldown menu: Setup→Memory options ) shown in Figure 2-2, select
desired memory space to be programmed. By default, the selected option is All Memory and it is
correct for most programming tasks (Section 2.1.5 describes how to use the memory configuration
window).
NOTE: The user can select which segments of memory are written to or read from.

Following these steps creates a working setup that can program target devices using the MSP Gang
Programmer. Click the Save Project As button to save this configuration settings. These settings can be
loaded again later and modified, if necessary (one project holds one configuration). After saving the
project, use the buttons described in the following sections to perform the desired actions.
2.1.1.1
GO
Click the GO button in the Main Dialog GUI (or F9 key on the keyboard) to start programming. The
progress and completion of the operation are displayed in the Results group. The result is shown as one
of the following:
Idle status
Test in progress. For power on/off, dc voltage is correct.
Access enabled
Access denied (for example, the fuse is blown)
Device action has been finished successfully
Device action has been finished, but result failed
2.1.1.2
Erase
Click the Erase button in the Main Dialog GUI to erase a segment of memory (sets each byte to 0xFF).
Use the Memory Options configuration screen shown in Figure 2-2 to specify which addresses should be
erased (Section 2.1.5 describes in detail how to use the memory configuration window). This action
succeeds after the programmer has attempted to erase the specified memory segment. Use the Blank
Check function to verify that this segment has been properly erased.

Blank Check
Click the Blank Check button in the Main Dialog GUI to check that the contents of specified memory have
been properly erased. This function is best used after erasing the same segment of memory, using the
button described above. Use the same Memory Options configuration screen shown in Figure 2-2 to
specify which addresses should be erased (Section 2.1.5 describes in detail how to use the memory
configuration window). This function succeeds when the specified memory segments are set to 0xFF, and
fails otherwise.
2.1.1.4
Program
Click the Program button in the Main Dialog GUI to write the contents of a code file(s) to flash memory on
the target device. Addresses specified in the code file(s) are used to determine where the program is
written. Make sure that the regions of memory corresponding to the addresses in the code file are enabled
for writing in the Memory Options configuration screen shown in Figure 2-2 (Section 2.1.5 describes in
detail how to use the memory configuration window).
Configuration conflicts may arise during programming. It is possible that the code the user has chosen is
too big to fit in the flash memory of the target MCU, or the appropriate memory segments have not been
enabled in the Memory Options configuration screen. If this is the case, a warning message appears to
notify the user of insufficient memory; however, the user is still allowed to proceed. If the user proceeds
despite the warning, only the portion of code that fits within the MCU's enabled flash memory is written.
This function succeeds after the programmer has attempted to write code to the specified memory
addresses. Use the Verify function to ensure that the code has been correctly copied to flash on the target
MCU.
2.1.1.5
Verify
Click the Verify button in the Main Dialog GUI to verify that the contents of the target MCU's flash memory
have been properly programmed. This function is best used after programming the same segment of
memory, as performed using the button described above. Make sure that the same memory segments are
enabled in the Memory Options configuration window shown in Figure 2-2, as during programming
described above, to ensure all programmed segments are verified (Section 2.1.5 describes in detail how
to use the memory configuration window).
If configuration conflicts arose during programming that indicated that the MCU did not contain sufficient
memory for the code to be programmed (either enabled segments or total memory was too small), then
the Verify function verifies only the code that was programmed and ignores the code that could not fit in
memory. This function succeeds if the code in flash matches the code file, and fail otherwise.
2.1.1.6
Read
Click the Read button in the Main Dialog GUI to read the contents of the target MCU's flash memory. Use
the Memory Options configuration screen shown in Figure 2-2 to specify which addresses should be read
(Section 2.1.5 describes in detail how to use the memory configuration window).
Once used, data is displayed in the Flash Memory Data window as shown in Figure 2-4. This window can
be selected in the View→Flash Memory Data pulldown menu. The Flash Memory Data viewer, shown in
Figure 2-4, displays the code address on the left side, data in hex format in the central column, and the
same data in ASCII format in the right column. The contents of the code viewer can be converted to TI
(*.txt) or Intel (*.hex) file format by clicking on the "TI hex" or "INTEL" button.

2.1.2 Programming From Image
A programming configuration like the one created in Section 2.1.1 can be stored in the form of an image.
The advantage of an image is that it contains both the configuration options necessary for programming
as well as the code files that are flashed to target devices. Moreover, only images can be saved to internal
MSP Gang Programmer memory and used in Standalone mode, in which the programmer can operate
without being connected to a PC. Using the From Image mode allows the user to test images with full GUI
support before committing them to production.
Once an image has been created, it can be used to greatly simplify programming by using the procedure
described in Section 2.1.6. Figure 2-5 shows the main dialog GUI where the From Image option is
selected for programming (top left corner). Here the user can load an image from MSP Gang Programmer
internal memory. An image can be created in Interactive Mode and saved to the programmer. One of 16
different images can be selected from internal memory, or one image from each external SD-Card can be
used.

NOTE:
www.ti.com
MSP Gang Programmer internal memory and SD-Card are mutually exclusive.
To avoid confusion during programming, connecting an SD-Card to the MSP Gang
Programmer disables its internal memory used for other images. Therefore, when an SDCard is connected to the programmer only the image on the SD-Card is usable or
accessible. If the SD-Card is empty, or contains a corrupted image, then it must be
disconnected before MSP Gang Programmer internal memory can be used.
NOTE: This figure uses the From Image Mode (see the Mode section near the top left corner). The user can load
an image from MSP Gang Programmer internal memory. Saved images contain all configuration necessary
for programming and all code files. An image can be created using the Interactive Mode and saved to the
programmer. One of 16 different images can be selected from internal memory, or one image from each
external SD-Card can be used.

Figure 2-5 highlights several parts of the GUI. The drop-down menu in the Object in Image memory group
(top right) is used to select which image is used for programming, because up to 16 different images might
be available. In the same group, the Config. from Image option is enabled, meaning that all configurations
options, such as which devices are enabled or power options are being taken from the image.
Sometimes it is useful to use the basic files from an image, such as the MCU type and code files, but also
make a few minor modifications to test a different configuration. Figure 2-6 shows the additional
configuration options available when the Config. from Image button is disabled. These are high-lighted in
red and include which devices are enabled for programming, target VCC and current, interface,
communication, and security. However, these changes cannot be committed to the image. If the user
wishes to change the current image's configuration or code files then the image needs to be recreated
using the original project file and procedure described in Section 2.1.6.

2.1.4 Programming in Standalone Mode
The MSP Gang Programmer supports a Standalone mode of programming target devices. In this mode
the MSP Gang Programmer can only use images for programming because they contain a complete
configuration and code files necessary for the procedure. If the user has not already created an image
then follow the procedure outlined in Section 2.1.6. When viewed from the GUI, Figure 2-8 shows that all
GUI options are disabled and the MSP Gang Programmer hardware buttons have to be used for
programming.
NOTE: This figure uses the Standalone mode (see the Mode section near the top left corner). All GUI options are
disabled; the MSP Gang Programmer can only be operated using physical controls on the programmer itself.
Standalone mode allows the user to program a target device using an image either from internal memory (up
to 16 different images), or an external SD-Card, without the use of a desktop or laptop computer.
Figure 2-8. Main MSP Gang Programmer Dialog GUI, Standalone Mode
After images have been download to the internal memory or after an SD card with a valid image is
connected to the MSP Gang Programmer, proceed with programming in Standalone mode. Use the arrow
buttons (up/down) and the enter button to select a desired image for programming. A description of the
selected image is displayed on the bottom line, and it is the same description that was created in the GUI
when the Save Image button was pressed (see Figure 2-9).

After the desired image has been selected, press the GO button on the MSP Gang Programmer hardware
to start programming. This button operates the same way as the GO button on the GUI. Progress of the
operation in Standalone mode is indicated by a flashing yellow LED and displayed on the LCD display.
The result status is represented by green and red LEDs on the MSP Gang Programmer and details are
displayed on the LCD display. If a green LED is ON only, then all targets have been programmed
successfully. If only the red LED is displaying, that all results failed. If red and green LEDs are on, then
result details should be checked on top of the LCD display. The LCD display shows target numbers 1 to 8
and marks to indicate failure or success: X for failure and V for success. When an error is reported, the
bottom line repeatedly displays an error number followed by a short description with time intervals of
approximately two seconds.
The selected image contains all necessary configuration options and code files required for programming;
however, the user can change the number of target devices being programmed using onboard buttons.
On the main display of the MSP-Gang Programmer (see Figure 2-10), use the up or down arrow buttons
to find the Target En/Dis option. Press the OK button to enter this menu. A sliding cursor appears below
the numbers representing each device at the top of the main display. Use the arrow buttons to underline
the device to enable or disable. Press OK to toggle the devices; press Esc to exit to the main menu. Press
GO to use the selected image to program the selected devices. If another image is selected or the current
image is selected again, the Enable and Disable options reset to what has been configured in the image.

2.1.5 Memory Setup for GO, Erase, Program, Verify, and Read
The GO, Erase, Program, Verify, and Read operations shown in Figure 2-1 use addresses specified in the
Memory Options dialog screen shown in Figure 2-2. The memory setup used by these operations has five
main options:
1. Update only – When this option is selected, the GO operation does not erase memory contents.
Instead contents of code data taken from the code file are downloaded to flash memory. This option is
useful when a relatively small amount of data, such as calibration data, needs to be added to flash
memory. Other address ranges should not be included in the code file, meaning that the code file
should contain ONLY the data which is to be programmed to flash memory. For example, if the code
file contains data as shown in TI format:
@1008
25 CA 80 40 39 E3 F8 02
@2200
48 35 59 72 AC B8
q
Then 8 bytes of data are written starting at location 0x1008 and 6 bytes of data starting at location
0x2200. The specified addresses should be blank before writing (contain a value of 0xFF). Before the
writing operation is actually performed, the MSP Gang Programmer automatically verifies if this part of
memory is blank and proceeds to program the device only if verification is successful.
NOTE: Even Number of Bytes
The number of bytes in all data blocks must be even. Words (two bytes) are used for writing
and reading data. In case that the code file contains an odd number of bytes, the data
segment is appended by a single byte containing a blank value of 0xFF. This value does not
overwrite the current memory contents (because Update only is selected), but verification
fails if the target device does not contain a blank value of 0xFF at that location.
2. All Memory – This is the most frequently used option during programming. All memory is erased before
programming, and all contents from the code file are downloaded to the target microcontroller's flash
memory. When the microcontroller contains an INFO-A segment that can be locked (for example the
MSP430F2xx series contains DCO constants at locations 0x10F8 to 0x10FF), then INFO-A can be
erased or left unmodified. The including locked INFO-A segment should be selected or unselected
respectively. When INFO-A is not erased, none of the data is saved into INFO-A, even if this data is
specified in the code file. In addition, the DCO constants in the Retain Data in Flash group should be
selected if the DCO constants should be restored after erasing the INFO-A segment.
3. Main memory only – Flash information memory (segments A and B, C, D) are not modified. Contents
of information memory from the code file are ignored.
4. Used by Code File – This option allows main memory segments and information memory segments to
be modified when specified by the code file. Other flash memory segments are not touched. This
option is useful if only some data, like calibration data, needs to be replaced.
5. User defined – This option is functionally similar to options described before, but memory segments
are explicitly chosen by the user. When this option is selected, then on the right side of the memory
group, in the Memory Options dialog screen, check boxes and address edit lines are enabled. The
check boxes allow the user to select information memory segments to be enabled (erased,
programmed, verified). Edit lines in the Main Memory group allow the user to specify the main memory
address range (start and stop addresses). The start address should specify the first byte in the
segment, and the stop address should specify the last byte in the segment (last byte is programmed).
Because the main memory segment size is 0x200, the start address should be a multiple of 0x200; for
example, 0x2200. The stop address should specify the last byte of the segment to be written.
Therefore, it should be greater than the start address and point to a byte that immediately precedes a
memory segment boundary; for example, 0x23FF or 0x55FF.

Writing and Reading BSL Flash Sectors in the F5xx/F6xx MCUs
The MSP430F5xx and MSP430F6xx microcontrollers have BSL firmware saved in flash memory sectors.
By default, access to these sectors (Read or Write) is blocked, however it is possible to modify the BSL
firmware if required, which allows the user to upload newer or custom defined BSL firmware. These BSL
sectors are located in memory starting at 0x1000 to 0x17FF. The MSP Gang Programmer software
handles modification of these BSL flash sectors using the same method as all other memory sectors.
However, to avoid unintentional erasing of BSL sectors, the most commonly used memory option, All
Memory , blocks access to these BSL sectors. Access to BSL sectors is unlocked only when the Used by
Code File or User defined option is selected and desired selected BSL sectors are enabled, as shown in
Figure 2-11. Contents of BSL sectors can be read even when the All Memory option is selected.
NOTE: The user can select which segments of memory are written to or read from. The selected configuration
shows how the user can configure the programmer to overwrite segments of memory used by the Bootstrap
Loader (BSL).

2.1.6 Creating and Using Images
An image contains the code files and the configuration options necessary for programming of a target
device. Images can be stored as a binary file (".mspgangbin") in internal MSP Gang Programmer memory
(or SD card), or as an image file (".mspgangimage") on disk for redistribution. Image files intended for
redistribution can be encrypted with additional security features described later in this section.

Creating an image is done in Interactive Mode by following the same steps described in Section 2.1.4
followed by pressing the “Save Image File As…” or “Save to Image” buttons. The first button saves the
code files and configuration options as a binary file and image file locally on disk, and the second button
saves this information directly to the MSP Gang Programmer internal memory. Note that in order to use
the MSP Gang Programmer in Standalone mode you need to program at least one image to internal
memory or read a binary file from an SD card (via the SD card connector on the MSP Gang Programmer).
If you intend to modify the contents of your image at a later date it is advisable to save the configuration
options as a project. Since an image is read-only, reading a project file is the only way to recreate images
easily without reentering the configuration options from scratch. Once the project is loaded, a change can
be made and a new image with the same name can be created to overwrite the previous one.
In total, 16 different images can be saved internally in the MSP Gang Programmer or one image can be
saved on an SD card. Each image can be selected at any time to program the target device(s). The MSP
Gang Programmer also allows the image to be saved in a file, either to be saved on an SD card or to be
sent to a customer. In order for the image file to be usable from the SD card, copy only the binary file
(".spgangbin") to the SD card and preserve the proper extension (Note that binary files are not encrypted).
For redistribution to a customer, the image file can be sent and encrypted with additional security features.
When a new image is saved to a file or to a MSP Gang Programmer internal memory, an image
configuration screen appears (see Figure 2-12). Enter any name up to 16 characters. This name is
displayed in the GUI image selector (see Figure 2-1) on the bottom line of the MSP Gang Programmer
LCD screen when the corresponding image is selected. Press OK when the name is entered.
Once you have created a programming setup using the steps mentioned above, it is useful to store it in
the form of an image. The advantage of an image is that it contains both the configuration options
necessary for programming as well as the code files that are flashed to target devices. Moreover, only
images can be saved to internal MSP Gang Programmer memory and used in Standalone mode, where
the programmer can operate without being connected to a PC.
Before the user proceeds to making images; however, it is advisable to save the MSP Gang Programmer
setup as a project first. This is recommended because images cannot be modified once created, only
overwritten. Therefore, if the user wants to change an image that has already been created without
recreating the whole configuration from scratch then it is necessary to load the corresponding project file.
Once the project is loaded, a change can be made and a new image with the same name can be created
to overwrite the old one.
Images can be saved to the programmer's internal memory, or on an external SD-Card. A total of 16
different images can be saved internally, or one image can be saved on an SD-Card. Each image can be
selected at any time to program the target device(s). The MSP Gang Programmer also allows the image
to be saved in a file, either to be saved on an SD-Card or to be sent to a customer. When the code file
and configuration are ready to be saved, press the Save Image button to save to MSP Gang Programmer
internal memory, or the Save Image to file button to save to a file.
Whether the new image being created is saved to a file or to MSP Gang Programmer internal memory, an
image configuration screen appears (see Figure 2-12). Enter any name up to 16 characters. This name is
displayed in the GUI image selector (see Figure 2-1) and it is displayed on the bottom line of the MSP
Gang Programmer LCD screen when the corresponding image is selected. Press OK when the name is
entered.

3. Selected PC - Hardware Fingerprint number – Image can be opened only on the dedicated
computer with the same hardware fingerprint number as the number entered in the edited line above.
Figure 2-14 shows a window with the hardware fingerprint number. An example usage scenario would
involve calling an intended user to provide the hardware fingerprint number of their computer and
entering it within this configuration window. This restricts opening this image to only the dedicated
computer running MSP Gang Programmer software.
NOTE: The fingerprint can be used to secure the project where, for example, only a computer with a matching
hardware fingerprint can be used to view and edit the project.

The image file can be copied to internal MSP Gang Programmer memory and used for programming
target devices. Select the desired image number in the GUI and press the Load Image from File button
(see Figure 2-1). This selected image is subsequently be used for programming target devices.
2.1.7 Programming From Image File
An image file can be used to program target devices from a self-contained read-only file that has all the
necessary configuration options and code files already included. By selecting the “From Image File” Mode
you can use an image file created using the steps described in Section 2.1.6. If the image is password
protected you are prompted to enter the password before you can use the image. Alternatively, if the
image is restricted to be used on a specific PC you are unable to use the image unless your PC matches
the hardware fingerprint (for instructions on how to use images from MSP Gang Programmer internal
memory see Section 2.1.2).

2.1.8 Programming From SD Card
The MSP Gang Programmer can program target devices with an image loaded from an external SD card.
To program from an external SD card, copy a binary file (".mspgangbin") created using steps described in
Section 2.1.6 to the root directory of the SD card (preserve the original extension ".mspgangbin"). If
multiple binary files are present in the root directory of the SD card, the first one found is used (the first
one found is not necessarily the first one alphabetically). To ensure that the desired binary file is used,
verify that only one binary file with the proper extension .mspgangbin is present in the root directory. The
name of the selected file is displayed on the LCD screen of the MSP Gang Programmer.
When the SD card is connected to the MSP Gang Programmer, internal memory is disabled and an image
can only be read from the SD card. This mechanism has been deliberately implemented to aid in
production because inserting an SD card to the MSP Gang Programmer leaves users with only one option
for programming a target device and, therefore, less possibility for misconfiguration errors.
2.1.9 File Extensions
MSP Gang Programmer software accepts the following file extensions:
Code hex files
*.txt
*.s19,*.s28,*.s37
*.hex
*.a43
Texas Instruments
Motorola
Intel
Intel hex format with extensions specified by IAR

Data from code files and from flash memory can be viewed and compared in data viewers. Contents of
the selected file can be viewed by selecting the View→Code File Data option from the drop-down menu.
The Code data viewer, shown in Figure 2-17, displays the code address on the left side, data in hex
format in the central column, the same data in ASCII format in the right column. Data in hex format is
displayed from 0x00 to 0xFF for addresses corresponding to the code file. Data from other addresses is
displayed as double dots (..). If code size exceeds flash memory size in the selected microcontroller, this
warning message is displayed first.

All procedures in the MSP Gang Programmer are divided into small tasks to be executed in series. When
first task is finished successfully, then the next task is started. Each task has is own consecutive number
assigned by the task manager when the image is created. The most commonly executed tasks are listed
below:
• Initialization
• Open Target Device
• Close Target Device
• Erase
– Segment
– Main memory
– Info memory
– BSL memory
• Blank check
• Program
• Gang Program (program unique data to each target)
• Write RAM
• Write GANG RAM (write unique data to each target)
• Verify
• Read memory
• Save Info-A
• DCO calibration
• Retain Info-A
• SetPC and run
• Capture PC and Stop
• Stop PC
• Secure device
• Finish
For example, the operations Erase, Program ,and Verify execute the following tasks:
• Initialization
• Open Target Device
• Erase
• Blank check
• Program
• Verify
• Close target and finish.
These tasks execute the easiest programming process in small MCU devices. The aforementioned tasks
can be divided into smaller tasks that only erase one segment, erase info segment, or erase one block of
the main memory. For that reason, many more tasks are displayed in the report window than are
described above. For example, when programming the MSP430F5438 the following information would be
displayed in the report window:

This report indicates that sectors INFO-B, INFO-C, INFO-D, and the main memory block have been
erased (tasks 2 to 14) blank checked (tasks 15 to 22), programmed (tasks 23 to 28) and verified (tasks 29
to 34). Finally, access to target devices is closed and the programming process is finished. Length of task
description (including consecutive task number) is limited to 16 characters to be able display this
information on the third line of the MSP Gang Programmer LCD display.
The MSP Gang Programmer can process up to 1000 tasks per one image saved in internal memory.
Having that number of available tasks and one or more code files saved in internal memory (total memory
footprint of up to 512 kbytes in one image), the MSP Gang Programmer gives the user significant flexibility
to perform custom programming procedures. If for any reason the code files and task scripts require more
than 512 kbytes of memory, then the next image memory can be taken and combined with the first one for
one larger image block (1Mbyte or more). The MSP Gang Programmer has internal flash memory of
8Mbyte that can, if desired, all be used to form one image with a memory footprint of 8Mbyte.
Error messages are displayed similarly to status messages, however, programming is terminated if the
error is related to all target devices. Subsequently, if the problem is resolved or the faulty target device is
disabled, then the programming procedure can be restarted to complete the programming process. The
result for all devices is reported in the results section (green or red icons). When the global status is
reported as FAIL, see the result section for details. Similarly, the MSP Gang Programmer uses red and
green LEDs to indicate the result of its operations (red indicates failure) and details are displayed on the
LCD display. Below is the list of errors reported in the MSP Gang Programmer.

Self Test
The MSP Gang Programmer Self Test program allows to test most of the hardware for correctness.
Connect the programmer to a computer running MSP Gang Programmer software. If the user is utilizing a
Gang Splitter, then connect it to MSP Gang Programmer hardware (this allows the Self Test to find short
circuits in the Gang Splitter). Disconnect all target devices, because any connected devices can modify
the test results and make them invalid.
Activate the Self Test by choosing the Tools→Self Test option from the drop-down menu. Press the Start
Self Test button, as shown in Figure 2-19, to begin. If the Self Test reports any problems then it is
advisable to send the test report to TI technical support for assistance.

Benchmarks
This section shows the results of timing benchmarks used on the MSP Gang Programmer to measure the
programming speed. Each table shows the result of the benchmark when programming with the JTAG and
SBW interfaces. Identical programming speed is seen whether programming one device or eight devices
simultaneously, because programming each MCU is done in parallel.

Firmware Interface Protocol
www.ti.com
3.2
Firmware Interface Protocol
The MSP Gang Programmer supports a UART communication protocol at baud rates from 9.6 to 115.2
kbaud in half duplex mode. The default baud rate at startup is 9.6 kbaud. This allows for communication
between the MSP Gang Programmer and devices that have a lower communication speed than the
maximum 115.2 kbaud. It is recommended that after startup the communication speed be increased to the
common maximum for both devices to enable faster communication. If the control device has a USB
interface with a virtual COM port, then it is recommended to use USB for communication between the
control device and the MSP Gang Programmer, because it is several times faster than via RS-232.
Communication requires one start bit, eight data bits, even parity bit, and one stop bit. A software
handshake is performed by a (not) acknowledge character.
3.3
Synchronization Sequence
To synchronize with the MSP-GANG Programmer the host serial handler transmits a SYNC (CR)
character (0x0D) to the MSP-GANG Programmer. The MSP-GANG Programmer acknowledges successful
reception of the SYNC character by responding with a DATA ACK character (0x90). If the SYNC is not
received correctly, no data is sent back. This sequence is required to establish the communication
channel and to react immediately to line faults. The synchronization character is not part of the data frame
described in Section 3.4.1. When communication is established, the synchronization character is not
required any more, but it can be send at any time for checking the "alive" status if required.
The synchronization character is not part of the data frame described in Section 3.4.1.
3.4
Command Messages
The MSP-GANG has a few type of messages with mandatory responses for each received command.
• Short TX messages with one byte only
"Hello"
Tx ->
Rx ->
0x0d (CR)
0x90 (ACK)
Get Progress Status
Tx ->
Rx ->

0xA5
0x80 0x00 <...data...> (without Check Sum)
Standard TX messages with data frame
Tx ->

or
or
or
0x3E, CMD, <...data...>, < Check sum >
0x90 (ACK)
0xA0 (NACK)
0xB0 (In Progress) (use Get Progress Status for monitoring)
0x80, 0x00, <...data....>, < Check sum >
3.4.1 Frame Structure
The data frame format follows the TI MSP430 serial standard protocol (SSP) rules, extended with a
preceding synchronization sequence (SS), as described in Section 3.3. The MSP Gang Programmer is
considered the receiver in Table 3-1, which details the data frame for firmware commands. The
redundancy of some parameters results from the adaptation of the SSP or to save boot ROM space.
The data frame format of the firmware commands is shown in Table 3-1.
• The first eight bytes (HDR through LH) are mandatory (– represents dummy data).
• Data bytes D1 to Dn are optional.
• Two bytes (CKL and CKH) for checksum are mandatory
• Acknowledge done by the MSP Gang Programmer is mandatory.

3.4.2 Checksum
The 16-bit (2-byte) checksum is calculated over all received/transmitted bytes, B1 to Bn, in the data frame
except the checksum bytes themselves. The checksum is calculated by XORing words (two consecutive
bytes) and bit-wise inverting (∼) the result, as shown in the following formulas.
CHECKSUM = INV [ (B1 + 256 × B2) XOR (B3 + 256 × B4) XOR...XOR ((Bn – 1) + 256 × Bn) ]
or
CKL = INV [ B1 XOR B3 XOR...XOR Bn–1 ]
CKH = INV [ B2 XOR B4 XOR...XOR Bn ]
An example of a frame for the Execute Self Test command with checksum would appear as:
0x3E 0x35 0x06 0x06 0x00 0x00 0x00 0x00 0x00 0x00 0xC7 0xCC
3.5
Detailed Description of Commands
3.5.1 General
After the prompt byte (0x3E) and the command identification byte CMD, the frame length bytes L1 and L2
(which must be equal) hold the number of bytes following L2, excluding the checksum bytes CKL and
CKH. Bytes A1, A2, A3, A4, LL, LH, and D1 to Dn are command specific. However, the checksum bytes
CKL (low byte) and CKH (high byte) are mandatory. If the data frame is received correctly and the
command execution is successful, the acknowledge byte ACK (0x90), in progress byte (0xB0) or received
message with header byte (0x80) as the first one. Incorrectly received data frames, unsuccessful
operations, and commands that are not defined are confirmed with a DATA_NACK = 0xA0.
3.5.2 Commands Supported by the BOOT Loader
3.5.2.1
"Hello" Command
Short TX messages with one byte only
Tx ->
Rx ->
0x0d (CR)
0x90 (ACK)
A response is sent only when the <CR> (0x0D byte) has been detected and when it is not the byte used
as the part of the data frame. This command can be useful for checking communication with the MSPGANG. When there is no response, then the baud rate should be changed. After power-up, the USB
interface is used for communication with the MSP GANG; however, the RS-232 receiver is also active. To
reestablish communication between USB and RS232, the "Hello" command must be sent a minimum of
three times via RS232. After this, an ACK (0x90) is transmitted via RS232. This sequence also works in
reverse, to reestablish communication between RS232 and USB.

3.5.2.10 Get Progress Status
The Get Progress Status command is a low-level command and can be used at any time, even if the
MSP-GANG is busy with other tasks. It replies to the command without interrupting the currently serviced
process. Some commands that have the long execution time requires use the Get Progress Status
command for monitoring the current state. For example, the Main Process command that can be executed
a few seconds or more, responding with character "In Progress 0xB0" as fast as the command has been
received and accepted. The communication link has been released and ready to use the Get Progress
Status command. Now the current status and progress data can be monitored by polling the Get Progress
Status command. Contents of the progress status contains current task number, chunk number, and
information about what tasks have been already finished (erase, blank check, program, verify and more).
Additionally, the comment displayed on the LCD display is also available in the progress status message.
This makes it possible to mirror the progress status on a PC screen and for the status on the PC screen to
appear the same as it is in the MSP-GANG LCD display. The internal firmware the progress status buffer
is always updated when the new task or new chunk is executed. In cases where the LCD is updated
frequently, it might not be possible for the PC screen to exactly mirror it. If polling is done more frequently,
then all messages on the PC can be updated almost in real time. Polling can be fast, but it is not
recommended to send the Get Progress Status command within the 20-ms interval. The MSP-GANG has
internal 8 level FIFO buffer for progress status (8 internal buffers - 50 bytes each). This allows messages
to be retrieved even if status has been changed a few times in interval 20 ms, as long as the next task is
bigger and the status is not updated within the next 100 ms.

Detailed Description of Commands
www.ti.com
One of the bytes (byte 6) in the progress status contains information as to whether the process is still in
progress or if it is finished. If the process is finished, then the programmer is ready to get the next
command. If the process is in progress, then only the Get Progress Status command can be used. Do not
send any other commands. The next command can also be accepted, but the new command bytes would
be collected in the RX buffer until the MSP-GANG is ready to service it. When the first valid byte of the
new command has been received (byte prompt '>' 0x3E ), then the receiver cannot get the Get Progress
Status command, because the 0xA5 byte, instead of the Get Progress Status command, is treated as a
data byte in the data frame.
When the Get Progress Status command is detected (single 0xA5 byte if it is not the frame data contents)
then the current status (50 bytes) is transmitted from the MSP-GANG with following data:

target.
3.5.3 Commands Supported by Application Firmware
Commands supported by the application firmware give access to target device. All features provided by
the MSP-GANG programmer and available in the MSP-GANG GUI and MSP-GANG DLL are accessible
by these functions. Some of the commands that allows control of the MSP-GANG programmer are
described in the following sections; however, commands that provide data transfer and script information
between MSP-GANG and MSP-GANG DLL are not described here. Users should use the GUI software
package (MSP-GANG executable and MSP-GANG DLL) for preparing data for programming, save it in the
internal memory or SD card, verify if that works, and then use the commands described in the following
sections to control the programming process via RS-232 or USB interface. If it is possible, then its is
recommended to use the MSP-GANG DLL and control the MSP-GANG programmer via the DLL rather
than directly via RS-232 or USB interface using the low-level communication protocol. The MSP-GANG
DLL allows full control of the MSP-GANG programmer.

Detailed Description of Commands
www.ti.com
The Select Image command sets a number for the current image. After this command, all operations that
the MSP-GANG performs use this image. The GANG430 supports 16 images, 0 through 15. The default
image after power on is 0.
A1: holds a number of the image to set (0x00 to 0x0F).
NOTE: When the SD card is inserted to SD slot, then the SD card is selected as the default image
and the Select Image command has no effect.
3.5.3.2
Main Process Command
Tx ->
Rx ->
3E 31 4 4 0 0 0 0 CKL CKH
B0 (In Progress)
The Main Process command begins the gang programming cycle, using the operations defined in the SD
or internal image memory. The result of the command execution can be determined using the Get
Progress Status command described in Section 3.5.2. It should be noted that the Main Progress
commands responds as soon as the command is accepted with byte In Progress (0xB0). When the byte In
Progress is received, then the Get Progress Status command should be via a polling technique for
monitoring the progress status. As long as the main process is not finished, byte 6 gives a response of InProgress data (0xB0). When the process is finished, byte 6 changes to ACK (0x90) or NACK (0xA0).
When ACK is received, then whole process is finished, and all results are available on bytes 8 to 32. See
the Get Progress Status command description for details. During the polling process, it is possible to
examine all bytes of the progress status and check the current state; for example, what targets are
connected or erased. In the comment bytes (34-50) is the current process, and the same message as is
displayed on the LCD display.
3.5.3.3
Set Temporary Configuration in MSP-GANG Command
Tx ->
Rx ->
3E 56 6 6 A1 0 2 0 DL DH CKL CKH
90 (ACK)
By default the Main Process command takes all configuration and setup from the image memory. It is
possible to overwrite some of the configuration parameters and execute the Main Process commands with
a modified configuration. The following parameters can be modified: Targets VCC, high or low current,
external VCC enable or disable, VCC settle time, communication interface (JTAG or SBW), enabled target
devices and enable process mask (for example, erase or program verify). The Set Temporary
Configuration in MSP-GANG command allows modification of these parameters.
When the Main Process command is finished, then the temporary setups are erased and the configuration
from the image memory is restored. When the modified configuration should be used in the next run, then
the temporary configuration should be transferred to MSP-GANG again before starting the Main Process
command.
The Set Temporary Configuration in MSP-GANG command transfers two data: address index (A1) and
one 16-bit data [DL (LSB byte) and DH (MSB byte)].
The following address indexes are defined:
CFG_TMP_CLEAR (2)
Data (DH, DH) is irrelevant.
Remove temporary configuration and take it from the image memory.
CFG_TMP_TASK_MASK (4)
Set the execution mask.
By default execution mask is 0xFFFF (execute all procedures).
Data (DH, DL) can be from 0x0000 up to 0xFFFF.
Currently supported bits in the execution mask:

Dynamic Link Library for MSP-GANG Programmer
4.1
Gang430.dll Wrapper Description
The Gang430.dll wrapper allows application software prepared for the old MSP430 Gang programmer to
control the new MSP-GANG programmer via the MSP-GANG.dll. Because the MSP- GANG programmer
has different functionality and features than the old MSP430 Gang Programmer, not all features provided
in the old programmer are supported in the same way by the MSP-GANG programmer. The Gang430.dll
wrapper allows an easy transition to the new programmer when using an old application, but it is
recommended to use MSP-GANG.dll for remote control of the MSP-GANG programmer to have access to
all features provided by the programmer.
When Gang430.dll is used, the following files must be located in the same directory where the application
software is located:
• Gang430.dll - DLL wrapper with the same name as the previous Gang430.dll
• Gang430.ini - Initialization file for compatibility with the old structure
• MSP-GANG.dll - New DLL that has access to MSP-GANG Programmer
Examples of using the GANG430.dll as a wrapper around the new MSP-Gang.dll are provided and can be
found in these locations (if the default installation directory was used):
C:\Program Files\Texas Instruments\MSP-GANG\Examples\C_Applications_Wrapper
and
C:\Program Files\Texas Instruments\MSP-GANG\Examples\Cpp_Applications_Wrapper
To use these examples, also copy the MSG-Gang.dll into the working directory.
Limitation
The MSP-GANG works in interactive mode. The image is not saved in the memory; however, the save
image option must be used as it is in the old Gang430.dll. An image is saved inside the DLL only (very
fast) and used when the Start command is executed. If USB communication is used, then programming is
fast. RS-232 communication is, of course, slower than USB, but it is still faster than the previous MSP430
Gang Programmer.
See the MSP430 Gang Programmer (MSP-GANG430) User's Guide (SLAU101) for list of commands used
in Gang430.dll.
4.2
MSP-GANG.dll Description
The MSP-GANG.dll is a Dynamic Link Library (DLL) that provides functions for controlling the MSP-GANG
Programmer. The MSP-GANG.dll controls the Gang Programmer via RS 232 or USB (VCP) interface. The
MSP-GANG.dll greatly simplifies the control of the MSP-GANG Programmer, because the user is isolated
from the complexities of the communication via USB or RS232 interface protocol. Together with the MSPGANG.dll are provided two more files that should be used during the compilation process.
• MSP-GANG.h: This file is the header file for the MSP-GANG.dll, and provides the function prototypes,
typedefs, #defines, and data structures for the functions of the MSP-GANG.dll. This file is normally
located in the same directory as the application source file and should be included by the application
source files. This file is used during compile time.
• MSP-GANG.lib: This file is the library file for the MSP-GANG.dll and is required to access the DLL
functions. This file is normally located in the same directory as the application source file and should
be added to the Linker Object / Library Modules list of the application. This file is used during link time.

MSPGANG_GetProgressStatus gets progress status from MSP-GANG. The data received contains a
Gang Mask of all processes done in the previous function. Each bit in the Gang mask represents one
targeted device:
bit 0 → Target 1, ....... bit 7 → Target 8
For example, when the connected_gang_mask == 0x7A, then targets 2, 4, 5, 6, and 7 are detected, and
communication with these targets is established. The cumulative mask contains the final result for all
targets.

4.2.44 MSPGANG_Set_IO_State
The MSPGANG_Set_IO_State modifies the static levels on the I/O pins (JTAG lines). The JTAG lines can
be set to the desired level (low or high) or they can be high impedance. The state and the level can be the
same on all outputs. The level on one selected line (RST, TDI, TDOI, TMS or BSL-RX) can be different for
each target.
