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:

USB and L4 discovery board

Just did the same exercise with a F072 discovery board. and ‘Voila’ that’s what I was looking for. It enumerates the first time I plug it in.
Not sure how that works with Win7, Does it need a special driver?
No problem though on Linux. I have now a new /dev/TTYACM0 device.

That broings uo the question: what is wrong with the L469 discovery board?
