STM32MP2

The STM32MP2 series embed an Arm Cortex-A35 (single or dual) and Cortex-M33 cores.

Depending on which core owns the Trusted Domain of the platform, the Arm Cortex-M33 can be:

Owner of Trusted Domain (TDCID) and launched by ROM code: M33-TD flavor (default)
A simple co-processor launched by the Cortex-A35 (STM32_M33TDCID=OFF): A35-TD flavor (not yet available on TF-M)

Note

Currently, this platform can only be built using GCC (GNU ARM Embedded toolchain).

Profile supported:
- TF-M Profile medium design: -DTFM_PROFILE=profile_medium
- TF-M Profile small design: -DTFM_PROFILE=profile_small
Hardware configuration:

This platform uses the device tree (DT) to describe the hardware available on boards. Based on Zephyr Devicetree concept
The board defines a default device tree (dts), but if needed, an external device tree can be used for your components (BL2 | S | NS):
- -DDTS_EXT_DIR=<external_dt_path>
- -DDTS_BOARD_S=<dts_file_secure>
- -DDTS_BOARD_NS=<dts_file_non_secure>
- -DDTS_BOARD_BL2=<dts_file_bl2>
