USB CDC Issue on STM32H747I-DISCO

StatusQ · ‎2024-12-11

Hello,

After trying almost everything I found online, I’m posting here for help.

I’m working with an STM32H747I-DISCO board, aiming to exchange data via USB CDC with Windows. I’ve configured the .ioc for USB CDC device (FS or HS) on the Cortex M7 core. However, the COM port does not appear on Windows.

Does anyone have a working .ioc configuration for USB CDC or got this running on this board? I’m running out of ideas and can't find a working project for this board as a start. It seems to be plagued by bugs/problems as well.

STM32CubeIDE Version 1.17.0
STM32CubeMX Version 6.13.0-RC5
MCU Firmware: FW_H7 V1.12.0

Thank you :)

Hi @StatusQ & welcome to ST Community :)

Try to port this example STM32CubeH7/Projects/STM32H747I-EVAL/Applications/USB_Device/CDC_Standalone at master · STMicroelectronics/STM32CubeH7

If still having issues, attach your IOC file and your project (preferably direct link via GitHub)?
