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:

STM32f070F6P6 USB VCP not working

Hi

I’m having troubles getting the VCP function on a stm32f070f6p6 project to work. I have two different boards with the IC, they seem to work just fine because I can upload und test GPIBs, the SPI interface and the UART ports without problems. Also the board connect to the Dfuse program and I can upload the dfu programs generated from the project hex files.

One board uses a 8MHz crystal. The other uses a 8MHz 3.3V CMOS Oscillator. Both seem to work just fine.

I also increased the stack size to 0x800 and the heap size to 0x400 as recommended and installed the latest drivers. I have some other STM32f070cbt6 boards on which VCP seems to work just fine. They should be the same apart from the package/pin difference and the program memory size shouldnt they?

I forget:

System: Win7
Version: Mars.2 Release (4.5.2)

Project file is attached.


Thank you so much in advance and regards
Andreas
