Flashing the device

Flashing the Board Using OpenOCD

The ST Nucleo-L552ZE-Q board includes an on-board ST-LINK programmer and can be flashed using OpenOCD.

Note

The upstream version of OpenOCD doesn't contain yet support for this board, so the source code version from http://openocd.zylin.com/#/c/5510 must be built to be able to flash this board (adapt the configure command with your preferred installation directory):

$ git clone https://git.code.sf.net/p/openocd/code openocd
$ cd openocd
$ git fetch http://openocd.zylin.com/openocd refs/changes/10/5510/5 && git checkout FETCH_HEAD
$ ./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=nucleo-l552ze-q flash

and debug via GDB by simply typing

make BOARD=nucleo-l552ze-q debug

Flashing the Board Using ST-LINK Removable Media

On-board ST-LINK programmer provides via composite USB device removable media. Copying the HEX file causes reprogramming of the board. This task could be performed manually; however, the cpy2remed (copy to removable media) PROGRAMMER script does this automatically. To program board in this manner, use the command:

make BOARD=nucleo-l552ze-q PROGRAMMER=cpy2remed flash

Note

This PROGRAMMER was tested using ST-LINK firmware 2.37.26. Firmware updates could be found on this STM webpage.

Accessing RIOT shell

Default RIOT shell access utilize VCP (Virtual COM Port) via USB interface, provided by integrated ST-LINK programmer. ST-LINK is connected to the microcontroller LPUART1.

The default baud rate is 115 200.

If a physical connection to LPUART1 is needed, connect UART interface to pins PG7 (LPUART1 TX) and PG8 (LPUART1 RX).

Note

Accordingly to the MCU Datasheet PG7 and PG8 pins are 5V tolerant (see table 21, page 108).

Supported Toolchains

For using the ST Nucleo-L552ZE-Q board we recommend the usage of the GNU Tools for ARM Embedded Processors toolchain.
