I have a Jetson AGX Orin, initially with Jetpack 5.0.1 DP. After running apt dist-update and rebooting the board, I can’t access it through ssh anymore when using an ethernet cable. It also doesn’t display video when connected to a monitor.
I can access the terminal through the micro USB port and the OS seems to be working. I can’t ssh into the board using the usb C port as well.
The board has a nvme ssd attached, so I was able to recover all my files. Now I’m trying to re-flash the board with Jetpack 5.1.1, but without success.
Only when in recovery mode, I can see the usb port with the command lsusb:
Bus 003 Device 008: ID 0955:7023 NVIDIA Corp. APX
Nothing shows up on the uart port when I try to flash the board.
I’m sending the SDK logs and the outputs on the uart when I reboot the board.
A lot of users have encountered this USB timeout issue when flashing their AGX Orin, but the root cause varies case by case, and there’s no single universal solution to this issue. Can you try different USB cables, USB ports, or in case you have another Ubuntu PC? Also, Ubuntu 18.04 seems to be more stable than Ubuntu 20.04 empirically.
If all of the above methods do no work, give these posts a try:
I’ve tried many usb cables and also tried to flash using another laptop with ubuntu 18.04, but the results are all the same.
Something interesting is that none of the jetson’s usb ports seem to work. While connected through the micro usb (using minicom), I tried to attach usb devices, such as a mouse, but they didn’t show up on the jetson’s lsusb. I was able to connect using the jetson’s wifi though.
And that’s correct, there was no log showing up in UART when I tried to flash the Jetson device.
Regarding the usb devices I mentioned, I believe I didn’t explain it well. I connected my host computer to the Jetson through the UART using minicom. That allowed me to connect to my user and access the terminal in the Jetson AGX Orin. I connected a mouse to the Jetson USB A port, and ran lsusb in the Jetson’s terminal (through minicom). The usb device (mouse) didn’t show up in the Jetson’t terminal (using lsusb), that I was accessing through minicom. Actually, lsusb was empty.
