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 two short videos (registration required) highlighting:

[SOLVED] Arch Linux: CUBE crashes with SIGSEGV

Hi Bernard,

Thanks a million! I can confirm that displaying Settings for C/C++ Build options also caused Eclipse to hang, and now running Eclipse after export SWT_GTK3=0 did the trick. I can see the settings and generate code in Cube.

Maybe you (someone?) could add my case to the FAQ you mentioned - it seems another symptom for the same problem.
