USBX standalone on STM32H5

[iguffick2]

I'm trying to use STM32CubeMX to generate a USBX Device CDC ACM in standalone mode (without using ThreadX).

I'm using a Nucleo-H563ZI to test with.

 

I can do this with ThreadX and get it working, but when I try the standalone configuration it doesn't work.

Is there any documentation, howto or guide on how to configure and setup USBX standalone on the H5 series?

(standalone, but HID not CDC)

I'd seen and tried to follow this one:

But it's specifically related to the H7. Some of the function calls in the section '3. code editing' don't seem right for the H5. e.g. HAL_PCDEx_SetRxFifo and HAL_PCDEx_SetTxFifo block of calls. Wouldn't this need to be replaced with HAL_PCDEx_PMAConfig(...) calls for the H5?

As far as official docs are concerned, I think that's about it on standalone USBX.

 

It's quite possible you have to adapt the example to other families. It's also true that this "supported" use case involves significantly more manual editing than is the norm with Cube.

Thank you so much for the link.
