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

NUCLEO H743ZI Unable to match requested speed 8000 kHz, using 4000 kHz.

No. I couldn’t.
I am coding on F429 instead of H743.
I guess I have to wait for fetch from ST. I had same issue on F429 before. After some fetch on SWorkbench, no problem with F429.
