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:

Getting STM32 to work with LLVM


Is there a way in System Workbench to change the GCC toolchain to LLVM when building for cortex-m based devices? Is there any resources that I could look in order to achieve this? Overall are there any disadvantages of choosing LLVM over GCC for baremetal based development Thanks?
