1 Overview[edit]

This stage explains how to get, install and boot the STM32MP15 Discovery kit with the Starter Package.

2 Open a terminal[edit]

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]

  • 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]

4.1 STM32CubeProgrammer[edit]

  • 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

STM32CubeProgrammer V2.11 is recommended for ecosystem release v4.0.0 More info.png

  • 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 still valid for higher version :

Splash screen
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
  • Go inside the binary folder:
 cd $HOME/STM32MPU_workspace/STM32MPU-Tools/STM32CubeProgrammer-x.y.z/bin/


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

4.2 USB serial link[edit]

  • 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/

5 Download the image[edit]

  • Create your STM32MP1 Starter Package directory on the host computer:
 mkdir $HOME/STM32MPU_workspace/STM32MP1-Ecosystem-v4.0.0
 mkdir $HOME/STM32MPU_workspace/STM32MP1-Ecosystem-v4.0.0/Starter-Package
 cd $HOME/STM32MPU_workspace/STM32MP1-Ecosystem-v4.0.0/Starter-Package
  • Download the STM32MP1-Ecosystem-v4.0.0 Starter Package to the following directory:
    $HOME/STM32MPU_workspace/STM32MP1-Ecosystem-v4.0.0/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


6 Populate the SDCard[edit]

  • Set the boot switches (located at the back of the board) to the off position
boot switches position to flash the board
  • Connect USB Type A to Type C cable between PC and CN7/USB_OTG port of the STM32MP157C-DK2 board
  • Power up the board
  • Press the reset button to reset the board
  • Launch STM32CubeProgrammer to get the GUI
  • On the right, select USB (not STLINK, set by default) in the connection picklist and click on "Refresh" button. Serial Number is displayed if USB is detected. Click on "Connect"
  • Select "Open File" tab and select $HOME/STM32MPU_workspace/STM32MP15-Ecosystem-v1.x.0/stm32mp1-openstlinux-xx-yy-zz/images/stm32mp1/flashlayout_st-image-weston the FlashLayout_sdcard_stm32mp157c-dk2-trusted.tsv, in the Starter Package installation folder.
  • Fill the "Binaries Path" by browsing up to folder $[Starter_Pack_Path]/images/stm32mp1
  • Click on "Download" to start the flashing process.
  • Progress is displayed with progress bar till completion popup message.

7 Boot the board[edit]

  • Set the boot switches (located at the back of the board) to the ON position
boot switches position to boot the board
  • Power up the board
  • Press the "Reset "button to reset the board
  • After few seconds, the board starts and automatically goes through the following screens
UBoot splash screen
Linux splash screen
Weston desktop
GTK demo launcher
  • If the board power supply doesn't supply enough current (3A), the red LED indicates the issue following the rules below:
blink console message boot process
2 times WARNING 500mA power supply detected

Current too low, use a 3A power supply!

Continue and red LED stays ON
3 times WARNING 1500mA power supply detected

Current too low, use a 3A power supply!

Continue and red LED stays ON
forever ERROR USB TYPE-C connection in unattached mode

Check that USB TYPE-C cable is correctly plugged

stop
forever USB TYPE-C charger not compliant with USB specification stop
