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:

Re: Simple GPIO problem



Yes, there is a bug for now in the “Run” feature (by opposition to “Debug”) that prevents it to flash the program; we’re working on this and it will be fixed in a future release.

In the mean-time, if you want to test a program compiled in the Release configuration (to check that optimization does not break anything) you may create a second debug configuration where:

  • In the Main tab
    • Select “Release/program.elf” as program to execute
    • Use the Release configuration
  • In the Startup tab:
    • Uncheck “Load symbols” (there is no symbols in a program compiled in the Release configuration)
    • Uncheck “Set breakpoint at: main” (there is no symbols)

Then you can start your program by debugging using this configuration; it will be flashed and started. However, when your test is finished, you should go to the Debug perspective (top right button) and stop the debugger (hitting the red square button); if you wand your program to run again, just hit the reset button on the board.
