NuttX CAN drivers on STM32H7x3

Hi Julian, I did the configuarations as you described above, but when I type “cansend can0 1122334455667788” or “candump can0” in the nsh console, nothing happens and i can’t receive or send any can messages through my USB-CAN device.
Are there any mistake in my working procedure? I just don’t know how to make it work…
