Introduction
The BlueBoard LPC1768-H is header board with LPC1768 from NXP. The LPC1768 is an
ARM Cortex-M3 based microcontroller for embedded applications.
Note: Please note that the BlueBoard-LPC1768-H has undergone a minor hardware change. The
new version is called Blueboard-LPC1768-H V2. V2 version has the been designed keeping in mind
the USB bootloader functionality. User can now use the SW2 for USB bootloading. Whereas in the
earlier version the user had to manually connect a wire on P2.12 to GND while powering ON or
resetting the board, to enter into the USB bootloader mode.
How do I identify the version of my board?
The Blueboard-LPC1768-H V2 boards have been labelled as <Product Number V2>. Check
the product numbering label at the backside of the board, as shown in the image below. If the board
has no V2 in the label then it is the earlier version of the board (and therefore you cannot USB
bootload using the SW2 button). In following figure the circle indicates the Blueboard-LPC1768-H
V2 board.

Getting Started
Before starting you would need the following.
Requirement
The requirement is put in two sections.
Hardware
• USB cable with type B connector
• 7.5V/1A DC power supply
• USB or Parallel JTAG
Software
•
•
•
H-JTAG Software
C Cross compiler(gcc / Keil / Rowley Crossworks for ARM)
PC / Laptop with Linux / Windows
Validating the BlueBoard LPC1768-H
Once you have all the accessories connect the USB cable and power jack. Switch on the
board.
The power LED D5 should glow. The Reset LED D4 should switch OFF when the RESET
button is pressed. The test LED D8 should blink 4 times after power up or RESET. If it remains ON
after blinking it confirms that EEPROM test was successful. To validate the USB interface get the
board into USB bootloader mode. The details of which are mentioned below.
How To Enter USB Boot Loader Mode?
Entering into USB bootloader mode is similar to ISP. If during reset or power up the ISP pin
is LOW the controller enters the ISP mode. Similarly to enter USB bootloader mode one needs to
hold some pin (as implemented in the USB bootloader program) LOW during reset or power up.
Note: You should have connected the USB cable to the PC.

For Blueboard-LPC1768-H
The USB bootloader program for this version looks for pin P2.12 to be held LOW during
reset or power up. To enter the USB bootloader mode connect the P2.12 pin (On connector J14) to
GND and press the SW1 (RESET) switch or power up. You should now see the board as a mass
storage device. You can now drag and drop your binaries onto this drive, remove the P2.12
connection to GND and then RESET using SW1 to execute the binary.
For Blueboard-LPC1768-H V2
Hold down SW2 (ISP) and SW1 (RESET), then release SW1 first and finally SW2. Now the
pre-loaded USB boot-loader allows you to enumerate the board as a Mass Storage Device. Drag the
compiled binary file and drop onto the device and reset the board using SW1 and the firmware
executes.
Using JTAG with BlueBoard
The BlueBoard LPC 1768-H v2.0 has a 20 pin male box connector. Using the NGX ARM
USB JTAG connect with the ribbon cable. Connect to the PC with USB cable.
