Use the procedure documented below to install the U-Boot firmware, Linux kernel and filesystem images to an SD Card the STM32MP1 module will be bootable from. Having completed the installation, the STM32MP1 SOM will boot to Linux from the SD Card on next reset / power on.
Please note that the installation will erase files previously installed on your SD Card. The SD card size should be at least 2GB for the Linux kernel and filesystem images to fit on the card.
- Insert SD card to the board.
- Follow the instructions in the Section 5 of https://wiki.st.com/stm32mpu/wiki/STM32MP15_Discovery_kits_-_Starter_Package#Installing_the_STM32CubeProgrammer_tool to install the STM32CubeProgrammer Tool to your host.
- Add STM32_Programmer_CLI to your PATH:
$ export PATH=$PATH:/bin:
$ STM32_Programmer_CLI
[[email protected] programmer]$ STM32_Programmer_CLI
-------------------------------------------------------------------
STM32CubeProgrammer v2.7.0
-------------------------------------------------------------------
Usage :
STM32_Programmer_CLI.exe [command_1] [Arguments_1][[command_2]
[Arguments_2]...]
...
- Power off the board and select the USB Serial Downloader mode (see in Selecting Boot Device).
- Check that the programming USB port appeared on the host (note the "Device Index" in the output):

- Power off the board.
- Set S4 for booting from SD Card.
- Connect with a wire JP3.1 and JP2 (any pin) on the baseboard. This will provide initial 3.3V power to SD Card.
- Apply the power and check the system boots from SD card:
