Just to clarify as you are using a devkit
-
If the board is in recovery mode, you won’t see any log from Jetson because it is the nature of Jetson.
-
The micro usb port on the NV devkit is to dump log. It is actually a UART port with adapter so it “looks like” a usb port but it does not have any function like real usb
-
Only the type C port opposite to the power jack side has the ability to flash board. Which means if you connect the wrong port, then no matter how many times you enter recovery mode, you won’t see it in your lsusb on host PC.
