This allows to concatenate spl and u-boot binaries together. Previously, both binaries has to be flashed separately at the correct offset (spl at offset 0 and u-boot at offset 0x8000). With this patch, only one binary is generated (u-boot-with-spl.bin) and has to be copied in flash at offset 0 using openocd for example or simply copied in exported mass storage.

As stm32f46-disco, stm32f769-disco and stm32746g-eval are very similar except their respective device tree file. These 3 boards uses the same TARGET_STM32F746_DISCO flag (so same include/configs/stm32f746-disco.h and same board file board/st/stm32f746-disco/stm32f746-disco.c)

To be able to compile these 3 boards, replace the hard-coded device-tree name in include/configs/stm32f746-disco.h by CONFIG_DEFAULT_DEVICE_TREE which is set in each board defconfig file with the correct value.

Install the required tools for U-Boot + + * install package needed in U-Boot makefile + (libssl-dev, swig, libpython-dev...) + + * install ARMv7 toolchain for 32bit Cortex-A (from Linaro, + from SDK for STM32MP15x, or any crosstoolchains from your distribution) + (you can use any gcc cross compiler compatible with U-Boot) + +2. Set the cross compiler:: + + # export CROSS_COMPILE=/path/to/toolchain/arm-linux-gnueabi- + +3. Select the output directory (optional):: + + # export KBUILD_OUTPUT=/path/to/output + + for example: use one output directory for each configuration:: + + # export KBUILD_OUTPUT=stm32f4 + # export KBUILD_OUTPUT=stm32f7 + # export KBUILD_OUTPUT=stm32h7 + + you can build outside of code directory:: + + # export KBUILD_OUTPUT=../build/stm32f4 + +4. Configure U-Boot:: + + # make <defconfig_file> + + For example with <defconfig_file>: + + - For **stm32f429 discovery** board : **stm32f429-discovery_defconfig** + - For **stm32f769 discovery** board with SPL: **stm32f769-disco_spl_defconfig** + - For **stm32f769 discovery** board without SPL: **stm32f769-disco_defconfig** + +5. Configure the device-tree and build the U-Boot image:: + + # make DEVICE_TREE=<name> all + + Examples: + + a) boot with SPL on stm32f746 discovery board:: + + # export KBUILD_OUTPUT=stm32f746-disco + # make stm32f746-disco_spl_defconfig + # make DEVICE_TREE=stm32f746-disco all + + b) boot without SPL on stm32f746 discovery board:: + + # export KBUILD_OUTPUT=stm32f746-disco + # make stm32f746-disco_defconfig + # make DEVICE_TREE=stm32f746-disco all + + c) boot on stm32h743 discovery board:: + + # export KBUILD_OUTPUT=stm32h743-disco + # make stm32h743-disco_defconfig + # make DEVICE_TREE=stm32h743i-disco all + + d) boot on stm32h743 evaluation board:: + + # export KBUILD_OUTPUT=stm32h743-disco + # make stm32h743-eval_defconfig + # make DEVICE_TREE=stm32h743i-eval all + +6. U-Boot Output files + + So in the output directory (selected by KBUILD_OUTPUT), + you can found the needed U-Boot files, for example:: + + - stm32f746-disco_defconfig = **u-boot-dtb.bin** and **u-boot.dtb** + + - FSBL = u-boot-dtb.bin + + - stm32f746-disco_spl_defconfig = **u-boot-dtb.bin**, **u-boot.dtb** and **u-boot-with-spl.bin** + + - FSBL + SSBL = u-boot-with-spl.bin + - SSBL = u-boot-dtb.bin + +7. Flash U-Boot files + +Plug STM32 MCUs board using the USB ST-Link connector, hence it will expose +the flash area as a mass-storage. In this mass-storage you will find the +following files: + +- DETAILS.TXT: give the bootrom version and build +- MBED.HTM: shortcul to the hardware board description web page from st.com. + +Copy/paste the u-boot.bin to this mass-storage. The "COM" LED will +blink alternatively red and green during the flash process. +When done the board will reboot automatically. + +In case of boot with SPL, by default SPL will try to load either a Linux +kernel (falcon mode) or, if the key "c" is maintained pressed, the main U-Boot.
