5. Installing the tools[edit source]

5.1. Installing the STM32CubeProgrammer tool[edit source]

STM32CubeProgrammer for Linux® host PC STM32CubeProgrammer for Windows® host PC
Download
  • Go on st.com to download the STM32CubeProgrammer software

Version v2.17.0

  • 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-2.17.0.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
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 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.

6.2. Image flashing[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 to the off position (boot from UART/USB)
Boot from UART/USB
  • Connect the USB type-C (OTG) port (4) to the host PC that contains the downloaded image
  • Insert the delivered microSD card into the dedicated slot (5)
  • Connect the USB type-C (power supply) port (1) to the power connector or a host PC (and check the power jumper position)
  • Press the reset button (7) 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-mpu-v24.06.26/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-mpu-v24.06.26/images/stm32mp2
Info white.png 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

Go see the STM32CubeProgrammer article:

  • to use another Flash device than the microSD card one
  • to know more about the flashing operation

6.3. Image flashing via raw image[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
 ./scripts/create_sdcard_from_flashlayout.sh flashlayout_st-image-weston/optee/FlashLayout_sdcard_stm32mp257f-ev1-optee.tsv
  • Flash the microSD from the Linux PC via dd command (follow the instruction available at the end of execution of create_sdcard_from_flashlayout.sh script).
 dd if=FlashLayout_sdcard_stm32mp257f-ev1-optee.raw of=<microSD destination> bs=8M conv=fdatasync status=progress 

For more information, see How to populate the SD card with dd command.

7. Booting the board[edit source]

Now that the image is flashed on the STM32MP257x-EV1 Evaluation board, let's finalize the system configuration:

  • Step 0: check that the LVDS display board is well connected.
  • Step 1: check the configuration of the switches and jumpers:
    • The boot related switches must be configured so that the device (e.g. microSD card ) on which the image has been flashed is selected as boot source.
The figure below shows the boot switches for the recommended boot from microSD card.
Boot from microSD card
  • Step 2: (optionally) connect a USB keyboard and/or a USB mouse (not provided) using the USB type-A ports (3 in the picture below).
  • Step 3: (optionally) connect an Ethernet cable (not provided) to the dedicated connector (2).

  • Step 4: if the Flash device is a microSD card, check that it is inserted into the dedicated slot (5).
  • Step 5: connect (check also the power jumper position)
    • either the USB Power – TypeC cable to the connector (1).
    • or power supply (5V, 3A) to the power connector (6) of the MB1936
  • Step 6: (optionally) install and configure a remote Terminal program (e.g. Minicom on Ubuntu Linux PC or Tera Term on Windows PC) onto your host PC, and connect the ST-LINK/V3 USB type-C port (1) to a host PC that runs a Terminal program with ST-LINK/V3 virtual port.
  • Step 7: press the reset button (7) to reset the board

The board boots and the system will be available after few seconds.



8. Checking the boot sequence[edit source]

Assuming you have performed the optional step 6 above, the information (coming successively from the TF-A, OP-TEE OS, U-Boot and the Linux operating system that is booting on the board), should be displayed on the host PC Terminal.

Info white.png Information
The information displayed below might differ from that on your own application, and should just be considered as an example.
First information scrolled on the remote Terminal during boot
Last information scrolled on the remote Terminal during boot

In parallel, a U-Boot splash screen picture is displayed on the board display (if one is connected to the board).DSI U-Boot splash screen.png

A user space graphical boot splash screen (PSplash) picture is then briefly displayed on the board display (if one is connected to the board).DSI user splash screen.png

When the boot process is complete, the launcher application is shown on the board display (if one is connected to the board).

More detail about this launcher application in GTK demo launcher page.

9. Mouse, keyboard and Ethernet hot-plugs[edit source]

Let's assume that the optional step 2 and step 3 were not achieved when setting up the system above.

When connecting a USB mouse, the following information is displayed by the Terminal program:

[  926.786326] usb 2-1.1: new low-speed USB device number 3 using ehci-platform

[ 1215.363377] IPv6: ADDRCONF(NETDEV_CHANGE): end0: link becomes ready
[ 1215.391068] Link is Up - 1000/Half

10. Remote and local Terminal programs[edit source]

As already explained in the step 6 above, a remote Terminal program can be installed and configured on your host PC in order to communicate with the board through a serial link or an Ethernet link: see How to get Terminal.

The remote Terminal on your host PC can be used to enter command lines, as shown below with the ip command to query the network interface parameters:

Example of command (ip) executed on the remote Terminal program


A local Terminal program can be launched directly on the board. Click on the small icon at the top left corner of the display (see the red arrow on the figure below):

Icon to launch a local Terminal program
Wayland Terminal program


Then the on-board Wayland Terminal can be used to directly enter command lines as shown below, still with the ip addr command to query the network interface parameters:

Example of command (ip addr) executed on the Wayland Terminal program


Consequently, unless an explicit restriction is mentioned, command lines can be run from both Terminals.

Note: in this article, any command executed on the board (through the remote Terminal or the Wayland Terminal) starts with , while any command executed on the host PC starts with .

11. Executing basic commands[edit source]

Info white.png Information
The outputs of the commands executed below are examples; the outputs obtained might differ.

11.1. Having a look at the OpenSTLinux directory structure[edit source]
