Support for the STM32 Nucleo-L552ZE-Q.
The Nucleo-L552ZE-Q is a board from ST's Nucleo family supporting ARM Cortex-M33 STM32L552ZE ultra-low-pawer microcontroller with TrustZone, 256KiB or RAM and 512KiB of Flash.

The ST Nucleo-L552ZE-Q board includes an on-board ST-LINK programmer and can be flashed using OpenOCD.
Once the patched OpenOCD is built and installed, you can flash the board simply by typing
and debug via GDB by simply typing
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:
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).
For using the ST Nucleo-L552ZE-Q board we recommend the usage of the GNU Tools for ARM Embedded Processors toolchain.
