NVIDIA JetPack Flashing Issues Q&A
Jetson usb-device mode issues
Q1: How to verify if usb-device mode is working?
A: After flashing and Jetson device booting up, usb-device mode is up . The expected results at this stage are:
192.168.55.1 is assigned to Jetson device, and
192.168.55.100 is assigned to host machine.
Q2: usb-device mode is already up and running, however, 192.168.55.100 not assigned on host. Why?
A: One possible reason is that usb-ethernet network interface is disabled on host machine? To enable it,
- Disconnect and Connect the USB cable connecting the jetson and Host-PC, and check the dmesg log. You might see a log similar to this: [107833.388835] cdc_ether 2-2:1.5 usb1: register ‘cdc_ether’ at usb-0000:00:1 4.0-2, CDC Ethernet Device, 72:40:f7:72:c9:fa
- Next go to Settings->Network and check all the wired connections for the same MAC-address.
- In the top right corner there will be an option to enable it.
- Next follow the procedure as provided by the SDK manager to install the SDK components
Q3: I tried thousands of ways, but the SDK Manager still reports “could not detect nvidia jetson device connected to usb”, what can I do?
A: You can also use wired cable to connect your host machine and Jetson board, and then install everything. Just make sure they are assigned to appropriate IP address:
192.168.55.10 (not 1) is assigned to Jetson device, and
192.168.55.100 is assigned to host machine.
