USB 2.0 port2 is no working on custom carrier board ,Could you please tell me how to fix the problem?
With almost 0 information here, I can only tell you to refer to the TX2 adaptation guide.
What module is that? TX2? TX2i? TX2-4GB? TX2-NX?
What software release do you want to use?
At least tell such information when you file topic.
TX2
