Board configuration¶
Virtual serial port¶
The first UART device is mapped to stdout.
Note: the board controller always configures the virtual serial port at 115200 baud with 8 bits, no parity and one stop bit. This also means that it expects data from the MCU with the same settings.
Note: to use the virtual serial port, ensure you have the latest board controller firmware installed.

Flashing the device¶
To flash, the OpenOCD Software is required.
Flashing is supported by RIOT-OS by the command below:
1 | make flash
|
To run the GDB debugger, use the command:
1 | make debug
|
Or, to connect with your own debugger:
1 | make debug-server
|
Image checksum¶
LPC ARM Cortext MCUs need a flash image checksum. When running make flash, this checksum is automatically generated and inserted into the firmware image right before flashing.
It depends on the lpc_checksum command-line utility, which can be installed using using pip install lpc_checksum or pip3 install lpc_checksum. After installing this utility, it should be available on your command-line.
Supported toolchains¶
For using the Seeeduino Arch Pro development kit we strongly recommend the usage of the GNU Tools for ARM Embedded Processors toolchain.
