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:

System Workbench for STM32

Is there any working cfg for stm32L0 ???

I installed the linux and win based version from the webpage (1.3). I used this successfully for my first builds.
Later I updated (you’ll get a popup notice) and everything is working fine with
my L152 and L4 discovery board

Again for you nucleo I suggest download the STM32CubeL0.zip file from STM. Lots of exampel and great way to start.
