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 (registration required) various documents highlighting:

USB and L4 discovery board

Thanks for the feedback ‘Diabolo38’. I followed your advice and build a CDC usb project using STMCube.
Was actually straight forward, less complicated than I thought. Some minor Macro error in the stmCube build code but easy to solve and everything builds. Thats the good part.

Runtime is actually still no success. I do not get any USB interrupts when plugging it into a host.
One thing I noticed os that the USB led in active without having it hooked up to the host.

I have the feeling it might be something hardware related. Anybody ever done sucessfully USB on a L469 discovery board?

Unfortunately the pins for USB are not available on the outside connector. Maybe a trace could shed some more light on the issue.
