Hi all, I’ve compiled the custom firmware for STM32-H7A3ZI-Q. Ardupilot compiled it successfully but USB is not show in COM Port. My hwdef sets PA11/PA12 for OTG_HS_DM/DP . When I enter DFU mode, the device pops up but not recognized on PC, and I am using STM32-H7A3ZI-Q breakout board.

Summary

Board: STM32-H7A3ZI-Q breakout board

  • Action: Successfully compiled and flashed custom ArduPilot firmware

  • USB Pins: PA11 (OTG_HS_DM) and PA12 (OTG_HS_DP)

  • Issue:

    • USB device appears in DFU mode but is not recognized by the PC
    • USB does not show up as a COM port after firmware upload
