HowTo: Recovery Mode for NVIDIA Jetson NANO Developer Kit

Its easy, but hard to find online, hence here for myself:

1. Connect Pins: GND <-> FC REC
2. Power On

Observe how your host can see the device connected via its USB gadget as below in dmesg:

[85283.237504] usb 1-6.2: new high-speed USB device number 84 using xhci_hcd
[85283.366258] usb 1-6.2: New USB device found, idVendor=0955, idProduct=7f21, bcdDevice= 1.02
[85283.366279] usb 1-6.2: New USB device strings: Mfr=1, Product=2, SerialNumber=0
[85283.366288] usb 1-6.2: Product: APX
[85283.366294] usb 1-6.2: Manufacturer: NVIDIA Corp.

Here the jumper cable and how I connected it for Recovery Mode (check the blue one):

Best wishes!
