| U-Boot on STMicroelectronics STM32MP1 |
| ====================================== |
| |
| 1. Summary |
| ========== |
| This is a quick instruction for setup stm32mp1 boards. |
| |
| 2. Supported devices |
| ==================== |
| U-Boot supports one STMP32MP1 SoCs: STM32MP157 |
| |
| The STM32MP157 is a Cortex-A MPU aimed at various applications. |
| It features: |
| - Dual core Cortex-A7 application core |
| - 2D/3D image composition with GPU |
| - Standard memories interface support |
| - Standard connectivity, widely inherited from the STM32 MCU family |
| - Comprehensive security support |
| |
| Everything is supported in Linux but U-Boot is limited to: |
| 1. UART |
| 2. SDCard/MMC controller (SDMMC) |
| 3. NAND controller (FMC) |
| 4. NOR controller (QSPI) |
| 5. USB controller (OTG DWC2) |
| 6. Ethernet controller |
| |
| And the necessary drivers |
| 1. I2C |
| 2. STPMIC1 (PMIC and regulator) |
| 3. Clock, Reset, Sysreset |
| 4. Fuse |
| |
| Currently the following boards are supported: |
| + stm32mp157c-ev1 |
| + stm32mp157c-ed1 |
| + stm32mp157a-dk1 |
| + stm32mp157c-dk2 |
| + stm32mp157a-avenger96 |
| |
| 3. Boot Sequences |
| ================= |
| |
| BootRom => FSBL in SYSRAM => SSBL in DDR => OS (Linux Kernel) |
| |
| with FSBL = First Stage Bootloader |
| SSBL = Second Stage Bootloader |
| |
| 3 boot configurations are supported: |
| |
| 1) The "Trusted" boot chain (defconfig_file : stm32mp15_trusted_defconfig) |
| BootRom => FSBL = Trusted Firmware-A (TF-A) => SSBL = U-Boot |
| TF-A performs a full initialization of Secure peripherals and installs a |
| secure monitor. |
| U-Boot is running in normal world and uses TF-A monitor |
| to access to secure resources. |
| |
| 2) The "Trusted" boot chain with OP-TEE |
| (defconfig_file : stm32mp15_optee_defconfig) |
| BootRom => FSBL = Trusted Firmware-A (TF-A) => SSBL = U-Boot |
| TF-A performs a full initialization of Secure peripherals and installs OP-TEE |
| from specific partitions (teeh, teed, teex). |
| U-Boot is running in normal world and uses OP-TEE monitor to access |
| to secure resources. |
| |
| 3) The "Basic" boot chain (defconfig_file : stm32mp15_basic_defconfig) |
| BootRom => FSBL = U-Boot SPL => SSBL = U-Boot |
| SPL has limited security initialisation |
| U-Boot is running in secure mode and provide a secure monitor to the kernel |
| with only PSCI support (Power State Coordination Interface defined by ARM). |
| |
| All the STM32MP1 boards supported by U-Boot use the same generic board |
| stm32mp1 which support all the bootable devices. |
| |
| Each board is configurated only with the associated device tree. |
| |
| 4. Device Tree Selection |
| ======================== |
| |
| You need to select the appropriate device tree for your board, |
| the supported device trees for stm32mp157 are: |
| |
| + ev1: eval board with pmic stpmic1 (ev1 = mother board + daughter ed1) |
| dts: stm32mp157c-ev1 |
| |
| + ed1: daughter board with pmic stpmic1 |
| dts: stm32mp157c-ed1 |
| |
| + dk1: Discovery board |
| dts: stm32mp157a-dk1 |
| |
| + dk2: Discovery board = dk1 with a BT/WiFI combo and a DSI panel |
| dts: stm32mp157c-dk2 |
| |
| + avenger96: Avenger96 board from Arrow Electronics |
| dts: stm32mp157a-avenger96 |
| |
| 5. Build Procedure |
| ================== |
| |
| 1. Install 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 STM32MP1, or any crosstoolchains from your distribution) |
| |
| 2. 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 <defconfig_file> |
| |
| - 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=<name> 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. Switch Setting for Boot Mode |
| =============================== |
| |
| You can select the boot mode, on the board with one switch : |
| |
| - on the daugther board ed1 with the switch SW1 : BOOT0, BOOT1, BOOT2 |
| |
| ----------------------------------- |
| Boot Mode BOOT2 BOOT1 BOOT0 |
| ----------------------------------- |
| Reserved 0 0 0 |
| NOR 0 0 1 |
| SD-Card 1 0 1 |
| eMMC 0 1 0 |
| NAND 0 1 1 |
| Recovery 1 1 0 |
| Recovery 0 0 0 |
| |
| - on board DK1/DK2 with the switch SW1 : BOOT0, BOOT2 |
| (BOOT1 forced to 0, NOR not supported) |
| |
| -------------------------- |
| Boot Mode BOOT2 BOOT0 |
| -------------------------- |
| Reserved 1 0 |
| SD-Card 1 1 |
| Recovery 0 0 |
| |
| - Boot mode of Avenger96 can be selected using switch S3 |
| |
| ----------------------------------- |
| Boot Mode BOOT2 BOOT1 BOOT0 |
| ----------------------------------- |
| Recovery 0 0 0 |
| NOR 0 0 1 |
| SD-Card 1 0 1 |
| eMMC 0 1 0 |
| NAND 0 1 1 |
| Reserved 1 0 0 |
| Recovery 1 1 0 |
| SD-Card 1 1 1 |
| |
| Recovery is a boot from serial link (UART/USB) and it is used with |
| STM32CubeProgrammer tool to load executable in RAM and to update the flash |
| devices available on the board (NOR/NAND/eMMC/SDCARD). |
| The communication between HOST and board is based on |
| - for UARTs : the uart protocol used with all MCU STM32 |
| - for USB : based on USB DFU 1.1 (without the ST extensions used on MCU STM32) |
| |
| 7. Prepare an SDCard |
| =================== |
| |
| The minimal requirements for STMP32MP1 boot up to U-Boot are: |
| - GPT partitioning (with gdisk or with sgdisk) |
| - 2 fsbl partitions, named fsbl1 and fsbl2, size at least 256KiB |
| - one ssbl partition for U-Boot |
| |
| Then the minimal GPT partition is: |
| ----- ------- --------- -------------- |
| | Num | Name | Size | Content | |
| ----- ------- -------- --------------- |
| | 1 | fsbl1 | 256 KiB | TF-A or SPL | |
| | 2 | fsbl2 | 256 KiB | TF-A or SPL | |
| | 3 | ssbl | enought | U-Boot | |
| | * | - | - | Boot/Rootfs | |
| ----- ------- --------- -------------- |
| |
| (*) add bootable partition for extlinux.conf |
| following Generic Distribution |
| (doc/README.distro for use) |
| |
| according the used card reader select the block device |
| (/dev/sdx or /dev/mmcblk0) |
| in the next example I use /dev/mmcblk0 |
| |
| for example: with gpt table with 128 entries |
| |
| a) remove previous formatting |
| # sgdisk -o /dev/<SDCard dev> |
| |
| b) create minimal image |
| # sgdisk --resize-table=128 -a 1 \ |
| -n 1:34:545 -c 1:fsbl1 \ |
| -n 2:546:1057 -c 2:fsbl2 \ |
| -n 3:1058:5153 -c 3:ssbl \ |
| -p /dev/<SDCard dev> |
| |
| you can add other partitions for kernel |
| one partition rootfs for example: |
| -n 4:5154: -c 4:rootfs \ |
| |
| c) copy the FSBL (2 times) and SSBL file on the correct partition. |
| in this example in partition 1 to 3 |
| |
| for basic boot mode : <SDCard dev> = /dev/mmcblk0 |
| # dd if=u-boot-spl.stm32 of=/dev/mmcblk0p1 |
| # dd if=u-boot-spl.stm32 of=/dev/mmcblk0p2 |
| # dd if=u-boot.img of=/dev/mmcblk0p3 |
| |
| for trusted boot mode : |
| # dd if=tf-a.stm32 of=/dev/mmcblk0p1 |
| # dd if=tf-a.stm32 of=/dev/mmcblk0p2 |
| # dd if=u-boot.stm32 of=/dev/mmcblk0p3 |
| |
| To boot from SDCard, select BootPinMode = 1 0 1 and reset. |
| |
| 8. Prepare eMMC |
| =============== |
| You can use U-Boot to copy binary in eMMC. |
| |
| In the next example, you need to boot from SDCARD and the images (u-boot-spl.stm32, u-boot.img) |
| are presents on SDCARD (mmc 0) in ext4 partition 4 (bootfs). |
| |
| To boot from SDCard, select BootPinMode = 1 0 1 and reset. |
| |
| Then you update the eMMC with the next U-Boot command : |
| |
| a) prepare GPT on eMMC, |
| example with 2 partitions, bootfs and roots: |
| |
| # setenv emmc_part "name=ssbl,size=2MiB;name=bootfs,type=linux,bootable,size=64MiB;name=rootfs,type=linux,size=512" |
| # gpt write mmc 1 ${emmc_part} |
| |
| b) copy SPL on eMMC on firts boot partition |
| (SPL max size is 256kB, with LBA 512, 0x200) |
| |
| # ext4load mmc 0:4 0xC0000000 u-boot-spl.stm32 |
| # mmc dev 1 |
| # mmc partconf 1 1 1 1 |
| # mmc write ${fileaddr} 0 200 |
| # mmc partconf 1 1 1 0 |
| |
| c) copy U-Boot in first GPT partition of eMMC |
| |
| # ext4load mmc 0:4 0xC0000000 u-boot.img |
| # mmc dev 1 |
| # part start mmc 1 1 partstart |
| # part size mmc 1 1 partsize |
| # mmc write ${fileaddr} ${partstart} ${partsize} |
| |
| To boot from eMMC, select BootPinMode = 0 1 0 and reset. |
| |
| 9. MAC Address |
| ============== |
| |
| Please read doc/README.enetaddr for the implementation guidelines for mac id |
| usage. Basically, environment has precedence over board specific storage. |
| |
| Mac id storage and retrieval in stm32mp otp : |
| - OTP_57[31:0] = MAC_ADDR[31:0] |
| - OTP_58[15:0] = MAC_ADDR[47:32] |
| |
| To program a MAC address on virgin OTP words above, you can use the fuse command |
| on bank 0 to access to internal OTP: |
| |
| example to set mac address "12:34:56:78:9a:bc" |
| |
| 1- Write OTP |
| STM32MP> fuse prog -y 0 57 0x78563412 0x0000bc9a |
| |
| 2- Read OTP |
| STM32MP> fuse sense 0 57 2 |
| Sensing bank 0: |
| Word 0x00000039: 78563412 0000bc9a |
| |
| 3- next REBOOT : |
| ### Setting environment from OTP MAC address = "12:34:56:78:9a:bc" |
| |
| 4 check env update |
| STM32MP> print ethaddr |
| ethaddr=12:34:56:78:9a:bc |
| |
| 10. Coprocessor firmware |
| ======================== |
| |
| U-Boot can boot the coprocessor before the kernel (coprocessor early boot). |
| |
| A/ Manuallly by using rproc commands (update the bootcmd) |
| Configurations |
| # env set name_copro "rproc-m4-fw.elf" |
| # env set dev_copro 0 |
| # env set loadaddr_copro 0xC1000000 |
| |
| Load binary from bootfs partition (number 4) on SDCard (mmc 0) |
| # ext4load mmc 0:4 ${loadaddr_copro} ${name_copro} |
| => ${filesize} updated with the size of the loaded file |
| |
| Start M4 firmware with remote proc command |
| # rproc init |
| # rproc load ${dev_copro} ${loadaddr_copro} ${filesize} |
| # rproc start ${dev_copro} |
| |
| B/ Automatically by using FIT feature and generic DISTRO bootcmd |
| |
| see examples in this directory : |
| |
| Generate FIT including kernel + device tree + M4 firmware |
| with cfg with M4 boot |
| $> mkimage -f fit_copro_kernel_dtb.its fit_copro_kernel_dtb.itb |
| |
| Then using DISTRO configuration file: see extlinux.conf to select |
| the correct configuration |
| => stm32mp157c-ev1-m4 |
| => stm32mp157c-dk2-m4 |
| |
| 11. DFU support |
| =============== |
| |
| The DFU is supported on ST board. |
| The env variable dfu_alt_info is automatically build, and all |
| the memory present on the ST boards are exported. |
| |
| The mode is started by |
| |
| STM32MP> dfu 0 |
| |
| On EV1 board: |
| |
| STM32MP> dfu 0 list |
