STM32MP1

The instructions here will tell how to run OP-TEE on one of the supported STM32MP1 boards.

Supported boards

Board Name	Manufacturer	Boot media	Hardware Description
STM32MP135F-DK	STMicroelectronics	SDcard	Wiki STM32MP135x-DK
STM32MP157A-DK1	STMicroelectronics	SDcard	Wiki STM32MP157x-DKx
STM32MP157D-DK1
STM32MP157C-DK2	STMicroelectronics	SDcard	Wiki STM32MP157x-DKx
STM32MP157F-DK2
STM32MP157C-EV1	STMicroelectronics	SDCard (1)	Wiki STM32MP157x-EV1
STM32MP157F-EV1

(1): STM32MP157x-EV1 boards also integrate an eMMC device, a NOR flash and a Nand flash the system can boot on. OP-TEE distribution however only supports booting from the SDcard slot.

Build instructions

Follow the instructions at “get_and_build_the_solution”.

Configuration switch PLATFORM can be used to specify the target device as listed in table below:

Board Name	Build configuration directive
STM32MP135F-DK	PLATFORM=stm32mp1-135F_DK
STM32MP157A-DK1 STM32MP157D-DK1	PLATFORM=stm32mp1-157A_DK1
STM32MP157C-DK2 STM32MP157F-DK2	PLATFORM=stm32mp1-157C_DK2
STM32MP157C-EV1 STM32MP157F-EV1	PLATFORM=stm32mp1-157C_EV1

When the build completes, generated image file sdcard.img can be found in the generated binary images directory ../out/bin/ from build root path. The images is a GPT multipartition image you can raw copy to the target SDcard using a tool like dd.

A usual short fecth/build/load shell sequence is like the one below:

$ repo init -u https://github.com/OP-TEE/manifest.git -m stm32mp1.xml
$ repo sync
$ cd build
$ make toolchains
$ make PLATFORM=stm32mp1-157C_DK2 all
$ dd if=../out/bin/sdcard.img of=/dev/sdX conv=fdatasync status=progress
$ sgdisk -e /dev/sdX

Command sgdisk -e fixes the GPT backup data which location depends on storage device effective size.
