SW4STM32 and SW4Linux fully supports the STM32MP1 asymmetric multicore Cortex/A7+M4 MPUs

   With System Workbench for Linux, Embedded Linux on the STM32MP1 family of MPUs from ST was never as simple to build and maintain, even for newcomers in the Linux world. And, if you install System Workbench for Linux in System Workbench for STM32 you can seamlessly develop and debug asymmetric applications running partly on Linux, partly on the Cortex-M4.
You can get more information from the ac6-tools website and download (registration required) various documents highlighting:

System Workbench for STM32


Hi everyone,

I’m testing this IDE and I am not able to select the MCU from the wizard. It only Allows me to select from boards.
How can I selelect a different MCU? There is no option to select by MCU.

I also tried to change from the Bulid Settings’ Target tab. I’m able to select from the combo list but it wont save changes. I click on apply and when I open back window changes are not saved.....

Thanks to all



Hi Alfredo,

Indeed, System Workbench needs you to define the board on which your program will run; after abere MCU chip wink

So you may:

  • either use one of the evaluation boards provided by ST supporting a chip close to the one you will use in your product
  • or define a custom board:
    • click on “create custom board” on the board selection page of the project creation wizard
    • you will have to provide the MCU and the debug interface to use (currently we only support ST-Link out of the box, but other members of th esite succeeded using J-Link from segger).

Hope this helps,


PS: to discover the IDE interface, you may follow the Getting Started with System Workbench for STM32 tutorial and read user documentation in the User Guide

I have a similar problem, when I set a custom or ST board this setting is only memorized ass long as AC6 is running. After shutting down and newly load the project, this setting is away cry
