Hello,

 I want to enter the boot console by UART2 on NX when it starts up.

What settings should I need to do? Now UART2 is default used for showing debug message.

You just need to connect debug cable between NVIDIA NX module and your host machine.Than you should start serial communication tool like gtkterm or picocom on your host machine. For gtkterm tool, it would be like

sudo gtkterm -p /dev/ttyUSB0 -s 115200

Or for picocom tool

sudo picocom /dev/ttyUSB0 -b 115200

Hi ozguryildiz

Yes,I konw how to connect debug serial port of NX. On my host, I use minicom to communicate with NX.And I can see the debug message by minicom. The problem is how to get into the bootloader’s console of NX by minicom. I want to boot OS of NX manually.
Thank you very much.

Hi @yalisun

You should connect to debug cable to your host machine and your NX module. You have to press a key when NX module boots and you should be able to get into the bootloaders console.
