is there any reason you have to use r32? Can you give the latest r35 a try?

Regarding serial connection, I think you can use the micro USB port.

Hi DaveYYY:
Sorry,I don’t have it on hand.

What do you mean? Are you talking about the L4T version, or the micro USB port?
Also, I don’t think you have to re-compile the kernel if don’t make any changes to it.
Just use the one in our BSP.

Just what i mentioned is the micro USB port.I misunderstand your responce message.Now i learn r35 is the version of L4T.
Do you think R35 is certainly OK? I will try it soon.

Are you using a custom carrier board? Otherwise, you should have a micro USB port available on your AGX Xavier DevKit.

Also, if you are using a custom carrier board, usually you need to turn off reading the EEPROM from it:
