For detailed information, please read the file in the delivered U-Boot code = board/st/stm32mp1/README
Also also available in official U-Boot Git: board/st/stm32mp1/README
1.1. STM32MP15 support[edit source]
Code :
- arch/arm/mach-stm32mp : arch specific code for all STM32MP family
- board/st/stm32mp1: generic STMicroelectronics board for STMP32MP1
- drivers/*/*stm32* : drivers
Configuration Files:
- defconfig file
- configs/stm32mp15_basic_defconfig
- configs/stm32mp15_optee_defconfig
- configs/stm32mp15_trusted_defconfig
- config files
- include/configs/stm32mp1.h
- Device tree
- arch/arm/dts/stm32mp157*-<board>.dts : same than kernel
- arch/arm/dts/stm32mp157*-<board>-u-boot.dtsi : addition for u-boot ( <<device tree>>-u-boot.dtsi automatically include in build process)
1.2. Selecting targets : choose defconfig and Device Tree[edit source]
Each boot chain is supported by one U-Boot configuration with defconfig
Boot chain | defconfig | FSBL | SSBL | TEE support |
---|---|---|---|---|
Trusted Boot | stm32mp15_trusted_defconfig | TF-A | U-Boot u-boot.stm32 |
- |
Trusted Boot with OP-TEE | stm32mp15_optee_defconfig | TF-A | U-Boot u-boot.stm32 |
yes |
Basic Boot | stm32mp15_basic_defconfig | SPL u-boot-spl.stm32 |
U-Boot u-boot.img |
- |
Several targets/ boards are supported with the associated device-tree (same name than kernel):
Board part number | Description | Device tree |
---|---|---|
STM32MP157C-EV1 | Evaluation board PMIC = MB1262+MB1263 |
stm32mp157c-ev1 |
STM32MP157C-ED1 | Evaluation daughter board PMIC = MB1263 |
stm32mp157c-ed1 |
STM32MP157A-DK1 | Discovery kit MB1272 |
stm32mp157a-dk1 |
STM32MP157C-DK2 | Discovery kit MB1272 + DSI screen |
stm32mp157c-dk2 |
1.3. Compilation[edit source]
see U-Boot_overview#U-Boot_build
With <mode> = 'basic', 'trusted' or 'optee'
$> make stm32mp15_<mode>_defconfig $> make DEVICE_TREE=<device tree name> all
- DEVICE_TREE: select the used device tree in arch/arm/dts
- KBUILD_OUTPUT: change the destination directory for the build
- EXT_DTB: select external device tree
2. Examples[edit source]
2.1. EV1 trusted boot[edit source]
$> make stm32mp15_trusted_defconfig $> make DEVICE_TREE=stm32mp157c-ev1 all
2.2. DK2 trusted boot[edit source]
Using export to select the device tree
$> export KBUILD_OUTPUT=../build/trusted $> export DEVICE_TREE=stm32mp157c-dk2 $> make stm32mp15_trusted_defconfig $> make all
2.3. ED1 basic boot[edit source]
$> export KBUILD_OUTPUT=../build/basic $> make stm32mp15_basic_defconfig $> make DEVICE_TREE=stm32mp157c-ed1 all
2.4. Trusted boot chain with external device tree[edit source]
$> make stm32mp15_trusted_defconfig
$> make EXT_DTB=boot/stm32mp157c-myboard.dtb all
