Tip

When using this board with RIOT, set the BOARD variable to seeeduino_arch-pro in your Makefile. If you follow the standard RIOT project structure, your Makefile should look like this:

./Makefile

# name of your application
APPLICATION = hello-world

# Change this to your board if you want to build for a different board
BOARD ?= seeeduino_arch-pro

# This has to be the absolute path to the RIOT base directory:
RIOTBASE ?= $(CURDIR)/RIOT

include $(RIOTBASE)/Makefile.include

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:

make flash

To run the GDB debugger, use the command:

make debug

Or, to connect with your own debugger:

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.
