4. Assembling the board[edit | edit source]

STM32MP257x-EV1 - board assembly

5. Installing the tools[edit | edit source]

5.1. Installing the STM32CubeProgrammer tool[edit | edit source]

	STM32CubeProgrammer for Linux^® host PC	STM32CubeProgrammer for Windows^® host PC
Download	Version v2.15.0 Go on st.com to download the STM32CubeProgrammer software Download the archive file on your host PC in a temporary directory Uncompress the archive file to get the STM32CubeProgrammer installers: unzip en.stm32cubeprog.zip
Installation	Execute the Linux installer, which guides you through the installation process. $> ./SetupSTM32CubeProgrammer-2.15.0.linux The path to the STM32CubeProgrammer binary must be added to the PATH environment variable either in each Terminal program in which the STM32CubeProgrammer binary needs to be used, using the following command: $> export PATH=<my STM32CubeProgrammer install directory>/bin:$PATH or once for all by creating a link to the STM32CubeProgrammer binary in a directory already present in PATH. For example, if "/home/bin" is in the PATH environment variable, run the following command: $> ln -s <my STM32CubeProgrammer install directory>/bin/STM32_Programmer_CLI /home/bin/STM32_Programmer_CLI	Execute the Windows installer, which guides you through the installation process.
User manual	Instructions to follow for using the STM32CubeProgrammer can be found in user manual, UM2237 available from ST web site, or in STM32CubeProgrammer#How to flash with STM32CubeProgrammer article.
Detailed release note	Details about the content of this tool version are available from ST web site at Release Note .

5.2. Preparing the USB serial link for flashing[edit | edit source]

It is recommended to use the USB (in DFU mode) for flashing rather than the UART, which is too slow.

Below indications on how to install the USB in DFU mode under Linux and Windows OS, respectively.

For Linux host PC or Windows host PC with VMWare:

The libusb1.0 package (including USB DFU mode) must be installed to be able to connect to the board via the USB port. This is achieved by typing the following command from the host PC terminal:

 sudo apt-get install libusb-1.0-0

To allow STM32CubeProgrammer to access the USB port through low-level commands, proceed as follows:

 cd <your STM32CubeProgrammer install directory>/Drivers/rules 

 sudo cp *.* /etc/udev/rules.d/

For Windows host PC:

Run the “STM32 Bootloader.bat” file to install the STM32CubeProgrammer DFU driver and activate the STM32 microprocessor device in USB DFU mode. This driver (installed by STM32 Bootloader.bat) is provided within the STM32CubeProgrammer release package. It is located in the DFU driver folder, \Drivers\DFU_Driver.

In case of issue, refer to How to proceed when the DFU driver installation fails on Windows host PC.

To validate the installation, the DFU driver functionality can be verified by following the FAQ instructions provided in how to check if the DFU driver is functional.

6. Downloading the image and flashing it on the board[edit | edit source]

6.2. Image flashing[edit | edit source]

The STM32CubeProgrammer tool is used to flash the STM32MP25 Evaluation board with the downloaded image.

Several Flash devices (microSD, eMMC...) are available on this board: see the STM32 MPU Flash mapping article if you want to know more about the supported Flash memory technologies, and the Flash partitions. The steps below consider the microSD card as the Flash device.

As explained in the boot chain overview, the trusted boot chain is the default solution delivered by STMicroelectronics. Thus, the steps below use the image for the optee boot chain.

Let's flash the downloaded image on the microSD card:

Set the boot switches (1) to the off position
Connect the USB type-C (OTG) port (2) to the host PC that contains the downloaded image
Insert the delivered microSD card into the dedicated slot (3)
Connect the USB type-C (power supply) port (4) to the power connector or a host PC
Press the reset button (5) to reset the board

Evaluation board connections for flashing

Go to the Starter Package directory that contains the binaries and the Flash layout files

 cd <Starter Package installation directory>/stm32mp2-openstlinux-6.1-yocto-mickledore-mp1-v23.06.21/images/stm32mp2

If you have followed the the proposition to organize the working directory, the command is
 cd Starter-Package/stm32mp2-openstlinux-6.1-yocto-mickledore-mp1-v23.06.21/images/stm32mp2

Information

The commands below are for a Linux host PC; however, they are similar for a Windows host PC except that STM32_Programmer_CLI is replaced by STM32_Programmer_CLI.exe.

Check that the STM32CubeProgrammer tool is installed and accessible; if not, go to the installation procedure (installing the tools)

 STM32_Programmer_CLI --h
      -------------------------------------------------------------------
                        STM32CubeProgrammer <tool version>                  
      -------------------------------------------------------------------

Get the device port location for the USB link

 STM32_Programmer_CLI -l usb

       -------------------------------------------------------------------
                         STM32CubeProgrammer <tool version>

6.3. Image flashing via raw image[edit | edit source]

The script create_sdcard_from_flashlayout.sh present with the downloaded image permit to generate a raw image ready to flash microSD on STM32MP25 Evaluation board.

Let's generate raw image and flash it on the microSD card:

Get the downloaded image
call the script create_sdcard_from_flashlayout.sh with the flashlayout of STM32MP25 Evaluation board as parameter
