1. Overview[edit | edit source]

This step explains how to get the Starter Package, then install and boot the STM32MP25 Discovery kit boards with the Starter Package.


2. Open a terminal[edit | edit source]

Open a terminal on the host computer.

Ubuntu terminal

All the commands preceded by have to be executed from the host computer terminal.

  • Create your STM32MPU workspace directory on the host computer:
mkdir $HOME/STM32MPU_workspace
cd $HOME/STM32MPU_workspace

3. Check the host computer Internet access[edit | edit source]

  • An Internet access through http and https protocols must be provided.

The command below enables checking for Internet access through http/https protocols:

wget -q www.google.com && echo "Internet access over HTTP/HTTPS is OK !" || echo "No internet access over HTTP/HTTPS ! You may need to set up a proxy."

If an 'OK' message is returned, the network is correctly configured.
In this case, skip the rest of this section.

Otherwise, a proxy for http/https protocols is required.
The best solution is to set this proxy through the shell variables http_proxy and https_proxy:

export http_proxy=http://<MyProxyLogin>:<MyProxyPassword>@<MyProxyServerUrl>:<MyProxyPort>
export https_proxy=http://<MyProxyLogin>:<MyProxyPassword>@<MyProxyServerUrl>:<MyProxyPort>

Check again the Internet access using the command:

wget -q www.google.com && echo "Internet access over HTTP/HTTPS is OK !" || echo "No internet access over HTTP/HTTPS ! You may need to set up a proxy."

4. Install the tools[edit | edit source]

4.1. STM32CubeProgrammer[edit | edit source]

  • Create your "STM32MPU tools" directory on the host computer:
mkdir $HOME/STM32MPU_workspace/STM32MPU-Tools
mkdir $HOME/STM32MPU_workspace/STM32MPU-Tools/STM32CubeProgrammer-x.y.z
  • Create a temporary directory in your STM32MPU workspace:
mkdir $HOME/STM32MPU_workspace/tmp
cd $HOME/STM32MPU_workspace/tmp


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

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

Version v2.18.0

  • 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-2.18.0.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 .


4.3. 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.


5. Test[edit | edit source]

  • Check that the STM32CubeProgrammer tool is properly installed and accessible:
STM32_Programmer_CLI --h
     -------------------------------------------------------------------
                       STM32CubeProgrammer vx.y.z                  
     -------------------------------------------------------------------

6. Download the image[edit | edit source]
