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:

Hack to remedy crashing issue on Mac

I also experience these random crash on compiling and some texte selection/deletion on MAC.
I have two computer running mac, one is crashing every two/three build, the other is stable ...

Problem is unclear but the embedded JRE is old and could be upgraded, my two cents...
Waiting for an update on this direction since April. Is that planed ?

To answer last question: Windows is stable as much as I know.
