Populate the target and boot the image

1. Open a terminal

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

2. Check the host computer Internet access

• 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."

3. Install the tools

3.1. STM32CubeProgrammer

• 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

• Download STM32CubeProgrammer in the following directory : $HOME/STM32MPU_workspace/tmp
  STM32CubeProgrammer v2.12.0 is recommended for ecosystem release unknown revision 4.1.0 .

• Uncompress the archive file to get the STM32CubeProgrammer installers:

 cd $HOME/STM32MPU_workspace/tmp
 unzip SetupSTM32CubeProgrammer.zip

• Execute the Linux^® installer, which guides you through the installation process. Select "$HOME/STM32MPU-Tools/STM32CubeProgrammer-x.y.z" as installation directory when it is requested by the installer.

 ./SetupSTM32CubeProgrammer-x.y.z.linux

The screenshots below have been obtained with old STM32CubeProgrammer V2.7.0. They are provided as examples and are still valid for higher versions :

Welcome page

Installation path

• Add the STM32CubeProgrammer binary path to your PATH environment variable:

export PATH=$HOME/STM32MPU_workspace/STM32MPU-Tools/STM32CubeProgrammer-x.y.z/bin:$PATH

• Check that the STM32CubeProgrammer tool is properly installed and accessible:

 STM32_Programmer_CLI --h
     -------------------------------------------------------------------
                       STM32CubeProgrammer vx.y.z                  
     -------------------------------------------------------------------

3.2. USB serial link

• Install the libusb on your host computer:

 sudo apt-get install libusb-1.0-0

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

 cd $HOME/STM32MPU_workspace/STM32MPU-Tools/STM32CubeProgrammer-x.y.z/Drivers/rules
 sudo cp *.* /etc/udev/rules.d/

4. Download the image

• Create your STM32MP1 Starter Package directory on the host computer:

 mkdir $HOME/STM32MPU_workspace/STM32MP1-Ecosystem-v4.1.0
 mkdir $HOME/STM32MPU_workspace/STM32MP1-Ecosystem-v4.1.0/Starter-Package
 cd $HOME/STM32MPU_workspace/STM32MP1-Ecosystem-v4.1.0/Starter-Package

• Download the STM32MP1-Ecosystem-v4.1.0 Starter Package into the following directory:
  $HOME/STM32MPU_workspace/STM32MP1-Ecosystem-v4.1.0/Starter-Package
• Uncompress the tarball file to get the binaries for the different partitions of the image, and the Flash layout files

 tar xvf FLASH-stm32mp1-openstlinux-5.15-yocto-kirkstone-mp1-v22.06.15.tar.xz
