Set the cross compiler: - - # export CROSS_COMPILE=/path/to/toolchain/arm-linux-gnueabi- - (you can use any gcc cross compiler compatible with U-Boot) - -3. Select the output directory (optional) - - # export KBUILD_OUTPUT=/path/to/output - - for example: use one output directory for each configuration - # export KBUILD_OUTPUT=stm32mp15_trusted - # export KBUILD_OUTPUT=stm32mp15_optee - # export KBUILD_OUTPUT=stm32mp15_basic - - you can build outside of code directory: - # export KBUILD_OUTPUT=../build/stm32mp15_trusted - -4. Configure U-Boot: - - # make - - - For trusted boot mode : "stm32mp15_trusted_defconfig" - - For trusted with OP-TEE boot mode : "stm32mp15_optee_defconfig" - - For basic boot mode: "stm32mp15_basic_defconfig" - -5. Configure the device-tree and build the U-Boot image: - - # make DEVICE_TREE= all - - example: - a) trusted boot on ev1 - # export KBUILD_OUTPUT=stm32mp15_trusted - # make stm32mp15_trusted_defconfig - # make DEVICE_TREE=stm32mp157c-ev1 all - - b) trusted with OP-TEE boot on dk2 - # export KBUILD_OUTPUT=stm32mp15_optee - # make stm32mp15_optee_defconfig - # make DEVICE_TREE=stm32mp157c-dk2 all - - c) basic boot on ev1 - # export KBUILD_OUTPUT=stm32mp15_basic - # make stm32mp15_basic_defconfig - # make DEVICE_TREE=stm32mp157c-ev1 all - - d) basic boot on ed1 - # export KBUILD_OUTPUT=stm32mp15_basic - # make stm32mp15_basic_defconfig - # make DEVICE_TREE=stm32mp157c-ed1 all - - e) basic boot on dk1 - # export KBUILD_OUTPUT=stm32mp15_basic - # make stm32mp15_basic_defconfig - # make DEVICE_TREE=stm32mp157a-dk1 all - - f) basic boot on avenger96 - # export KBUILD_OUTPUT=stm32mp15_basic - # make stm32mp15_basic_defconfig - # make DEVICE_TREE=stm32mp157a-avenger96 all - -6. Output files - - BootRom and TF-A expect binaries with STM32 image header - SPL expects file with U-Boot uImage header - - So in the output directory (selected by KBUILD_OUTPUT), - you can found the needed files: - - a) For Trusted boot (with or without OP-TEE) - + FSBL = tf-a.stm32 (provided by TF-A compilation) - + SSBL = u-boot.stm32 - - b) For Basic boot - + FSBL = spl/u-boot-spl.stm32 - + SSBL = u-boot.img - -6.
