STM32MP15 EV1 Evaluation Board

This page covers flashing an STM32MP15 EV1 board with LmP artifacts.

Getting the Required Software

STM32CubeProgrammer is used to flash the STM32MP15 EV1 board. This section shows how to download and set it up. Skip to the next section if you already have STM32CubeProgrammer installed.

  1. Download the STM32CubeProgrammer software for Linux®.

  2. Unzip it to a known location:

    mkdir <STM32CubeProgrammer_path>
    unzip en.stm32cubeprg-lin_v*.zip -d <STM32CubeProgrammer_path>
    
  3. Run the installer and follow the instructions on screen:

    ./SetupSTM32CubeProgrammer*.linux
    
  4. Export the STM32CubeProgrammer_path to the system path:

    export PATH=<STM32CubeProgrammer_path>/bin:$PATH
    
  5. To allow STM32CubeProgrammer to access the USB port through low-level commands, proceed as follows:

    cd <STM32CubeProgrammer_path>/Drivers/rules
    sudo cp *.* /etc/udev/rules.d/
    

For more information, check the STM32CubeProgrammer Installation page.

Preparation

  1. In your Factory, click on the latest platform build.

  2. Expand the run for stm32mp15-eval, and under the other folder, find and download flashlayouts-stm32mp15-eval.tar.gz.

  3. Unzip the file:

    tar -xvf flashlayouts-stm32mp15-eval.tar.gz
    

The file used for flashing is FlashLayout_stm32mp1-optee.tsv

Hardware Preparation

  1. Connect the USB OTG cable in the base board to the host machine.

  2. Set the boot switches in the CPU board to Serial Download Mode, 0000:

  3. OPTIONAL: For UART output in the USB connector on the CPU board, remove JP1 jumper and move JP4 and JP5 to the 2–3 position:

Flashing

  1. Turn on the board and verify that it is set for serial download mode:
STM32_Programmer_CLI -l usb
     -------------------------------------------------------------------
                       STM32CubeProgrammer v2.11.0
     -------------------------------------------------------------------

=====  DFU Interface   =====

Total number of available STM32 device in DFU mode: 1

 Device Index           : USB1
 USB Bus Number         : 001
 USB Address Number     : 001
 Product ID             : DFU in HS Mode @Device ID /0x500, @Revision ID /0x0000
 Serial number          : 002B00323438511836383238
 Firmware version       : 0x0110

2. Flash the board. Make sure to replace the command below with the USB Device Index from the previous step if needed:

STM32_Programmer_CLI -c port=usb1 -w FlashLayout_stm32mp1-optee.tsv

This can take a few minutes to complete. The process can be watched from the host console, UART output, or board display.

  1. Once the flashing procedure finishes, change the boot switches to eMMC boot, 0100:

  2. Reset the board to boot the installed LmP image.
