Each DHCOR STM32MP1 module comes with preprogrammed default bootloader.
Features/Supported interfaces
- Bootloader console (UART4)
- PMIC (STPMIC1APQR)
- DDR3 Memory (size is coded by DDR3 coding pins)
- CPU type (STM32MP151, STM32MP153 and STM32MP157)
- On-Board I2C (I2C4)
- microSD (SDMMC1)
- eMMC (SDMMC2)
- SPI boot Flash (QSPI_BK1)
- Gbit Ethernet KSZ9031 (ETH1)
- USB Host and Device
Download/Build U-Boot SPL and U-Boot binaries
There are two ways to get the required U-Boot binaries. These can either be downloaded or built from the sources by yourself. Follow one of the two steps below.
Download prebuilt binaries
Dropbox: u-boot_stm32mp1-testbench_2022.07_g5d247d61.zip (source)
Build binaries from source
Checkout source code
git clone -b v2022.07_testbench https://github.com/dh-electronics/u-boot-stm32mp1.git
cd u-boot-stm32mp1Download and extract toolchain Toolchain from: https://developer.arm.com/downloads/-/gnu-a

Attention: Do not switch off the voltage during the update
- Copy binaries to USB drive.
- Startup U-Boot, connect to console and plugin USB drive with binary files.
- Set update_sf command:
env set update_sf 'usb start && setexpr loadaddr1 ${loadaddr} + 0x1000000 && load usb 0 ${loadaddr1} u-boot-spl_stm32mp1-testbench_2022.07_g5d247d61.stm32 && env set filesize1 ${filesize} && load usb 0 ${loadaddr} u-boot_stm32mp1-testbench_2022.07_g5d247d61.itb && sf probe && sf erase 0 0x200000 && sf update ${loadaddr1} 0 ${filesize1} && sf update ${loadaddr1} 0x40000 ${filesize1} && sf update ${loadaddr} 0x80000 ${filesize} && env set filesize1 && env set loadaddr1'- Start bootloader update
run update_sf
