ST7MDTU5-EMU2B User Manual 1 - Introduction
1 INTRODUCTION
Note:
Thanks for choosing ST7! This manual will help you get started with the
ST7MDTU5-EMU2B emulator kit.
The ST7MDTU5-EMU2B emulator allows you to control the execution of programs that you have written for the ST7265x family of MCUs (see list below) and assists you in debugging your application hardware as well as your software. The
ST7MDTU5-EMU2B kit comes with the debugger software package—ST7 Visual
Debug—which contains all of the necessary resources to help you design, develop and debug ST7 application software running in a real environment.
If you come across any terms or abbreviations you do not understand, you can check their meaning in the Glossary on page 63.
First off, check that the ST7 MCU that you have picked for your application is in the list of devices supported by this version of the ST7MDTU5-EMU2B emulator:
Note:
Supported Devices
ST72651
ST72F651
ST72652
ST72F652
The Emulator Package is made up of two main parts:
• The Hardware Development System (ST7 HDS2), which is the common mainframe to all ST7 emulators.
• The ST7MDTU5-Active Probe, dedicated to the family, which constitutes the physical link between the emulator and your application.
When receiving the ST7MDTU5-EMU2B development tool, please refer to the Delivery checklist on page 11 to confirm that all of the contents of the package are present.
The emulator performs two main functions:
• It replaces the microcontroller in the application, by means of an emulation probe that is plugged into the application in place of the emulated MCU.
• It controls the internal data bus of the emulated microcontroller, providing arbitration and tracing capabilities on all accesses to any of the following resources:
5/71
1
1 - Introduction ST7MDTU5-EMU2B User Manual
ST7 HDS2 resources,
ST7MDTU5-Active Probe resources,
Application resources.
Therefore, you can have the emulator running your software in the application just as the emulated MCU would do, and have extensive tracing and control capabilities (i.e. keeping track of what the MCU does, and making it react in a specific way upon defined conditions).
In this way, it is possible to fully emulate microcontroller resources.
Please refer to Section 4.8: Emulation functional limitations and discrepancies
on page 55
for a description of the limitations on the current release of this emulator kit.

ST7MDTU5-EMU2B User Manual 1 - Introduction
Probe is connected to the ST7MDTU5-TEB, to which a device adapter can be fixed so that you can connect the emulator to your application board.
The emulator is operated from your host PC using STVD7, a state-of-the-art,
integrated development environment, from which you can configure and control the emulator, debug, edit and rebuild your application program.
The emulator is controlled using STVD7, (also referred to as ST7 Visual Debug).
STVD7 integrates all phases of an application development in a single, powerful and easy to use environment.
The graphical interface is composed of one main window which consists of an integrated set of windows, menus, toolbars and other elements that allow the user to create, build, debug and refine an application using a single tool. The visual environment can be personalized; the user can change the position of all windows, open or close individual elements, alter which windows are visible at startup, and save the configuration. User-defined toolbars may be created, and command icons added or removed from toolbars. The integrated syntax-color highlighting editor allows several source files to be edited in a single place.
Thanks to the powerful features of the debugger, the debugging and tuning of an application is made easier and quicker. Debugging with STVD7 (with an
ST7 HDS2 emulator) involves the following functional aspects:
• Loading the application.
• Defining the memory map and option configuration of the target MCU.
• Running the application.
• Viewing source and disassembled code.
• Setting instruction breakpoints.
• Setting data breakpoints.
• Using the Logical Analyser to impose counters and conditions on breakpoints and trace recording.
• Viewing variables, memory and registers.
• Viewing history of execution: trace (up to 1024 records) and call stack features.
Chapter 3: STVD7
on page 21, explains how to install ST7 Visual Debug on your
PC, and set up the emulator configuration so that you can begin your debugging session.
When your application is fully debugged, the ST7 EPROM programming board

About STVD7 debugging features
A number of advanced features are included in the STVD7 software:
• Data Breakpoints on the occurrence of a memory access via a read operation or a write operation, or both.
• Instruction Breakpoints on the occurrence of an opcode fetch.
• A Logical Analyser that allows you to control either the recording of the trace buffer, or a break in the execution of the application using a series of specific conditions (events).
• A Trace window to view the contents of the trace buffer, which permanently records in real time on 32-bits:
Address and data bus information.
Flag status and 4 external signal values.
You can record up to 1024 executed cycles. Using trace filtering, you can filter out only those cycles you wish to record in the trace buffer. You can equally control which of the recorded cycles are displayed in the Trace window using line filtering. Addresses, data, control/status bits and 4 user signals are displayed using mnemonic and user symbols.
• Internal synchronization signals can be output to either of two Trigger Outlets on the front panel of the emulator (OUT1 or OUT2). This feature enables you to count events using an external equipment, when optimizing software for example, or to synchronize an oscilloscope when debugging hardware.
• Hardware Events can be used to control the sending of signals to the trigger outputs.
• You can choose the output that you wish the signal to be sent to (i.e. either
OUT1 or OUT2).
• A Hardware Test function that allows you to perform a number of hardware tests on the Development Board, at your choosing. Refer to Running the

• A powerful online help facility can be invoked at any time to give additional information about the commands, the processor or the emulator kit.
3.4 Workspaces
STVD7 organizes project development and debugging into workspaces.
Workspaces allow you to store application and project settings and save them, so that each time you wish to work on the project, you will find all of the settings exactly as you left them.
Creating a workspace is the first thing that you need to do when using STVD7 for the first time or when starting any new project. You must have an open workspace to work with STVD7. How to create a new workspace is described in detail in
Section 3.6
. Sample workspaces for each supported toolchain are provided so that you can familiarize yourself with STVD7 (for a listing of sample workspaces, see
Table 1
).
Each workspace is comprised of three information sets: the project settings, the visual environment and debugging information.
• The project settings consists of the information necessary for a successful build of an application (commands to run, makefile file etc....). Your workspace’s project settings include the definition of your application toolchain
(see
Section 3.5
).
• The debugging information includes information on breakpoints, memory mapping, advanced breakpoints programs, trace etc..
• The visual environment consists of the open windows elements, along with their current layout, customized toolbars and menus. The visual environment is composed of two environments, one in the Build context and one in the
Debug context (see
Section 3.12
).
The above workspace information is stored in three types of files: a workspace file
(*.wsp) and two auxiliary files (*.wed and *.wdb).
Both project settings and debugging information is stored in the same workspace file (*.wsp). In addition, to allow you to use the same workspace file for any STVD7 version (such as the STVD7 Simulator version, STVD7 for HDS2 Emulator, STVD7 for DVP, and/or STVD7 for EMU3 Emulator), the project settings and debug information (such as the toolchain used, MCU emulated, memory mapping, etc.) are kept separately in the same
*.wsp
file for each STVD7 version.This allows you to use the same workspace file to debug the same application for two different
MCUs or MCU configurations on different STVD7 versions.
24/71
ST7MDTU5-EMU2B User Manual
3.5
3 - STVD7
Visual environment information (such as the location of debug windows, the appearance of toolbars, and other aspects of STVD7’s graphical interface) is saved in separate files for each of the two contexts of STVD7. Graphical interface preferences while in Build context are saved in a
*.wed file, and graphical interface preferences while in Debug context are saved in a
*.wdb
file. Each of these files is attached to a given workspace.
Note that if you move a workspace file (for example, mywork.wsp
) to a new folder, take care to move the associated
*.wed
and
*.wdb
files ( mywork.wed
and mywork.wdb
) with the workspace file in order to preserve the latest visual environment of your STVD7 session.
Toolchains and application files
A quick summary of development toolchains and application file types supported by STVD7 will help you in setting up your workspace.
Three different development toolchains are currently supported by the STVD7.
Each type of toolchain has its own application and executable file types, project environment and building tools (i.e. linkers and convertors):
• The ST7 macroassembler toolchain from STMicroelectronics, which generates either
.s19
or
.hex
executable files with various intermediate files, such as
.map
or
.lst
files.
• The Hiware C or Assembler toolchain, which generates
.abs
executable files with various intermediate files, such as
.o
or
.dbg
files.
• The Cosmic C or Assembler toolchain which generates
.elf
executable files with various intermediate files, such as
.o
or
.st7
files.
When you set up a workspace, you will need to define the following project settings:
• The toolchain to be used—Hiware, Cosmic or ST7 macroassembler.
• The executable file (
*.abs
,
*.elf
,
*.s19
or
*.hex
depending on toolchain—refer to
Table 2
).
• The maker program for the toolchain. The maker program can be a part of the toolchain software (such as Hiware’s maker.exe
) or you can choose to use a generic maker such as
Nmake.exe
or
Gmake.exe
(which is provided with the
STVD7).
• The maker batch file (
*.mak
or
*.bat
). This is a file which you create for each application which spawns the compilation and/or link step each time you wish to build or rebuild. In it, you define the conditions for recompiling, re-
25/71
3 - STVD7 ST7MDTU5-EMU2B User Manual
linking or both.
Default
*.mak
or
*.bat
files are often included with the toolchains—for example, maker.mak
is included with the Hiware toolchain and simply recompiles your application if it detects that the file has been saved since the start of your debugging session. The STVD7 software includes sample
*.mak
and/or
*.bat
files for each toolchain—these are listed in
Table 1
.

The user should verify that the options to include debug information were active during creation of the project files.
Table 2
summarizes the way each toolchain functions and lists the different file types (source files, intermediate files and executable files) used and produced by the toolchain. The executable file types

Note:
The executable file(s), source files and any necessary intermediate files (these are listed above and contain debug information necessary to the STVD) should be located in the same project directory. You do this when you define your workspace.
It is always preferable to have access to all of the files generated by the development toolchain. However, you can load
*.s19
or
*.hex
binary files directly and have limited debugging capabilities (refer to Section 3.8
).

Note:
Using the Configuration Setup dialog box (available from the MCU Configuration dialog box), you can also control what type of MCU configuration information is restored from a workspace file (*.wsp).
3.12 Debug context and Build context
There are two STVD7 contexts, the build context and the debug context. Until now, in creating a workspace, and defining your project settings, you have been in the build context. To proceed step—configuring your MCU—you need to change to the debug context.
Briefly, the two contexts are different in that:
• In the build context, you can open and close workspaces and build or re-build the application executable file.
• In the debug context you set the emulated MCU configuration (this step is described in
Section 3.13
) and debug the executable file created while in the build context.
The build context is the context set when starting STVD7. In this context, it is not necessary to be connected to an emulator and the debug commands are not available. You can also edit the source files of an application and perform the use the Build command to perform compile and link actions in an interactive and iterative way to re-build the application executable file.
In this context, the following debug actions can be carried out:
• Loading, running and stopping the application.
• Defining the MCU configuration (MCU options and memory mapping).
• Viewing source and disassembled code.
• Setting instruction breakpoints with a counter and/or condition.
• Setting data breakpoints.
• Viewing local variables, memory and ST7 registers.
• Viewing history of execution from the trace buffer or with the Call Stack feature analyzing the performance of a piece of code.

3 - STVD7 ST7MDTU5-EMU2B User Manual
3.12.3 Switching between contexts
The switch between contexts usually occurs when the Start Debugging and Stop
Debugging commands are used.
From the main menu, choose Debug>Start Debugging or Stop Debugging or click on the Start Debugging or Stop Debugging icons shown in
Chapter 3
.

Note:
Figure 22: Start Debugging and Stop Debugging icons
While debugging, the editor allows source files to be modified. To switch to the
Build context perform either a Build or Rebuild action or use the Stop Debugging
Configuring the MCU
After you create or open a workspace, the next step you must perform before starting your STVD7 debugging session is to define and configure the target device
(MCU) that you wish to emulate.
The target device is defined and configured from the MCU Configuration window.
1
First, ensure that you are in Debug context by clicking on . (STVD7 has two contexts: Debug context and Build context—these are described in
Section 3.12
.)
The first time you enter into the Debug context after having created a new workspace, the
MCU Configuration window will be opened automatically.
2
Select Tools>MCU Configuration from the main menu. The MCU
Configuration window will open.

Set the Target MCU. In the MCU name field, select the target device for which the application is intended from the dropdown box. Once a target MCU has been chosen, the Option configuration and the Memory configuration fields will show the default values for this device.
4
Configure the MCU Options and On-Chip Peripherals. All of the configurable options on your target hardware device are listed in the Option
configuration fields. Beside each option, a default value is given. You may change this value by clicking on it and choosing a new value from the drop down list. This allows you to configure your target device’s options and on-chip peripherals. Depending on the MCU selected, the default settings in the Option
configuration fields will change. It is up to you to configure those options that will impact your application so that the emulator accurately emulates your target device.
For more information about the configurable options available on your target hardware device, please consult your target MCU’s datasheet.

Configuring the MCU Memory. The default memory settings depend on the
MCU selected. However, you can configure the memory settings as you wish if your application requires non-default settings. This feature would enable you, for instance, to temporarily increase the ROM size during the development phase of your application.
42/71
Memory configuration fields
Graphic memory configuration viewer
Figure 24: Memory mapping
There are two methods for configuring the memory settings on the MCU: by typing in the start and stop addresses of each memory zone into the memory
configuration window, and by graphically moving the memory zone boundaries in the graphic memory configuration viewer (see
page 43
for more instruction).
Memory zone types
The left column of the memory configuration window indicates the address range of each memory zone. The right column indicates the memory type of each zone. Depending on your target MCU, the available memory types may be:
Peripherals, RAM, ROM, Stack, System, EEPROM, Reserved, Vectors,
ST7MDTU5-EMU2B User Manual 3 - STVD7
Application. Some of these zones can have their type and size modified, others cannot be modified. Their definitions and properties are explained as follows:
• Peripherals: Microcontroller internal or rebuilt peripherals registers. Their properties are defined as in the microcontroller datasheet. This memory cannot be modified.
• RAM: Random-Access-Memory of the microcontroller. This memory type can be modified.
• ROM: Read-Only Memory of the microcontroller. Write protected. This memory type can be modified.
• Stack: Stack of the microcontroller. This memory type cannot be modified.
• System: The emulator uses this space for emulation management. This memory type cannot be modified.
• EEPROM: This memory is internal to the microcontroller and is located inside the emulation device. The programming of this zone is done according to an automaton found in the datasheet. This memory type cannot be modified.
• Reserved: This memory zone is reserved as on the microcontroller. It is not allocated to any use and is write protected. This memory type cannot be modified.
• Vectors: This memory zone contains the user interrupt vectors zone. It is write protected. This memory type can be modified.
• Application: This memory type is microcontroller-specific. The user can add memory or peripheral resources on its hardware. It is not available on every emulator. Properties are linked to the user hardware. This memory type can be modified.
For most target MCUs, you may modify the following types of memory zone: RAM,
ROM, Reserved and Application. This feature would enable you, for instance, to temporarily decrease the RAM zone, increase the size of the ROM (to exceed what is available on the real microcontroller) during the first stages of development.
Once your program is functional, you can start to optimize its size by reducing your code and returning these zones to their original size. There are two different actions you may perform on the memory configuration:
• change the type of an entire existing zone.
• define a new zone of any type wherever possible.
To change an existing memory zone:
1
Select the memory zone to be modified.
43/71
3 - STVD7 ST7MDTU5-EMU2B User Manual
2
Click on the Modify button at the bottom of the window. A New MCU Memory
Range dialog box will open, allowing you to change either the address range and/or the memory type of the memory zone.

To create a new zone of any type:
1
Click on the Insert button. The New MCU Memory Range dialog box will appear.
2
Enter the address range of the new memory zone in the From and To fields.
3
Select the type of the new memory zone in the Type field.
4
Click OK to validate your choice.
The new memory zone will then appear in the MCU Configuration window unless you tried to create a new zone in a non-modifiable memory space (such as Stack or EEPROM).
To use the Graphic Memory Configuration viewer:
1
In the memory configuration window, click on the zone whose boundaries you wish to move.
2
Check the Selection auto zoom box in the upper right-hand corner. The graphical view of the memory configuration will be scaled so that the zone you have selected is easily visible.
3
At the upper and lower boundary of the zone, at the left-hand side of the graphical viewer, you will see a small triangle and rectangular box giving the boundary addresses of the memory zone. You can change a boundary address by dragging and dropping the triangle with the mouse to its new location. The triangle can be moved either up or down, left or right in the graphical viewer.
ST7MDTU5-EMU2B User Manual 3 - STVD7
The MCU configuration that you specify will, by default, be saved in a workspace file (
*.wsp
) for the project. The next time the application is opened, the STVD will automatically set the MCU configuration (as well as the layout of opened windows and other debug information) to the same conditions you had when you left the last debugging session.
If you do not wish your MCU configuration information to be saved in the workspace file, you must alter the default Configuration Setup options by clicking on the Conf... button.
Once in debug context, you are now ready to start debugging your application using the emulator.Full documentation on how to:
• control your STVD7 work environment
• use its integrated editor
