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:
I have used the STMCube IDE on a previous STM32 project with the ST-LINK interface on the STM32-F3-DISCOVERY eval board, but I’m now trying to build and load a project a vendor has supplied us with ( and they use system workbench ), and the debugger does nothing. System workbench reports some nonsense windows error about joining drives ( obviously someone is following a wrong pointer somewhere to the error string and this seems to be a common error among eclipse based IDEs on Windows whenever gdb “doesn’t work” ), and the RST and SWCLK signals coming out of the debug board don’t move the whole time, so it isn’t even trying to communicate. Any idea where to even start?
