When using this board with RIOT, set the BOARD variable to b-u585i-iot02a in your Makefile. If you follow the standard RIOT project structure, your Makefile should look like this:

# name of your application
APPLICATION = hello-world

# Change this to your board if you want to build for a different board
BOARD ?= b-u585i-iot02a

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

include $(RIOTBASE)/Makefile.include

Support for the STM32 B-U585I-IOT02A

Flashing the device

The ST B-U585I-IOT02A board includes an on-board ST-LINK programmer and can be flashed using OpenOCD. Note: The latest release (v0.11) of OpenOCD doesn’t contain yet support for this board, so the source code version from upstream master must be cloned and built:

$ git clone https://git.code.sf.net/p/openocd/code openocd
$ cd openocd
$ ./bootstrap
$ ./configure --prefix=<installation directory>
$ make -j
$ sudo make install

Once the patched OpenOCD is built and installed, you can flash the board simply by typing

make BOARD=b-u585i-iot02a flash

and debug via GDB by simply typing

make BOARD=b-u585i-iot02a debug

Supported Toolchains

For using the ST B-U585I-IOT02A board we recommend the usage of the GNU Tools for ARM Embedded Processors toolchain.

Important notice: With GCC 10, the tests/sys/malloc application doesn’t work. To use malloc, prefer GCC 9 which seems to work better.
