Jetson Xavier Nx iş not starting on Forced Recovery Mode

[nsdev]

Hi everyone,

I’m pretty new to Jetson boards. I’m trying to reflash my Jetson using the NVIDIA SDK Manager, but I can’t get the board into recovery mode properly.

Here’s what I’ve tried:

• I connected the FC REC pin (located near the camera connector) to GND in order to force recovery mode.
• Then I connected the Jetson to the host PC via USB.
• After powering on the Jetson, I removed the connection between the REC and GND pins (to avoid keeping it grounded).
• However, the SDK Manager still doesn’t detect the device, and the manual setup “Flash” button remains disabled.

If I don’t connect the FC REC pin to GND, the SDK Manager detects the Jetson, but the manual setup “Flash” button is not enabled — probably because it’s not in recovery mode.

I’ve tried many combinations, but nothing worked so far.

Any advice would be appreciated!

(I used on Virtual box Ubuntu 20.04 for installing Jetson to Ubuntu 20.04 sdk 5.1.3)

(I’m using Ubuntu 20.04 in a VirtualBox VM as the host system to flash Jetson using SDK Manager 5.1.3.)

Other than the VM, it sounds like you are doing everything correctly. In recovery mode the Jetson becomes a custom USB device; when fully booted the default software provides a virtual network device and a virtual partition you can mount with a README in it. Both use the same USB ID information, but you are correct that when fully booted you cannot flash.

During a flash USB will disconnect and reconnect, and even if the VM held the USB device at the start, then any misconfiguration would cause the USB to be lost at that moment. Not seeing recovery mode at all tends to mean the VM is failing USB under those circumstances.

I’m grateful — once I switched from VirtualBox to running on the actual system, the Jetson installations were completed successfully.

Thanks a lot
