I need to set the oem-config account and password; I boot the system first time after flush the SD card, follow the steps below;Getting Started With Jetson Nano Developer Kit | NVIDIA Developer
First I use Micro USB cable (only wires, no voltage level exchage) to connect computer (win10), I cannot found the com port, not any response; as shwn below; finally I have try other normal Jetson Nano module, this Micro USB hasn’t response.
Also I connect UART debug poart (with UART to USB transfer card), and the putty can open this com port to get some start up log.
So the question is why the my Micro USB cannot connect to host PC? (J48 is bridged, use the round connector to power the module; I have try two kits, same result) So I cannot get the oem-config interface. So it must use the MicroUSB to set the oem-config at first startup, Not the debug UART port?!
