USB CDC in STM32H563

[VKoen.1]

tried to set up a USB device serial emulation (CDC) for STM32H563. Started a Free RTOS based project project in STM32CubeMX. But there I only can activate USB as "device_only in the "connectivity" segment but do not find any other USB related settings. I did that previously with the stm32F series and there it was in STmCube, no prob.

The generated code also seems not to have the USBD_DESC_Private_Defines or similar things needed. 

Is it somewhere hidden under another name in STM32Cube? Or does STM32Cube does not support it? Or is this  CPU issue? Or do I need to somehow get me drivers from other places and when yes, from where?

You are invited, to use Azure /ThreadX . :)

Well, I for one will politely decline that invitation.

Hi @VKoen.1 

Which USB stack do you want to implement? If you are using ST Library stack, it is not implemented in CubeMX. You can check examples provided here.STMicroelectronics/stm32h5-classic-coremw-apps: Provide a set of applications for STM32H5xx series based on the STM32 Classic Core Middleware libraries.

Just to close this topic:

 

I got it running on a stm32H563 following STM advice

The only weak point was, that I had to switch off the ICACHE, probably because of a weakness in the STM code concerning read out of CPU serial number, but I did not need the speed, and so I was good
