Jetson System Backup and Flashing

1. Copy system.img from the filesystem partition to be flashed. Run the following command:
$ sudo ./flash.sh -r -k APP -G mmcblk0p1

Confirm the name of the generated image.
Check the target device configuration.

This step creates two copies in the directory: a sparse image (smaller than the original image) and an exact raw image ending with .raw.

Path to the PDK installation package directory, which contains the flash.sh script.

For example, if the image name is original.img, flash.sh will generate a sparse image named original.img and a raw image named original.img.raw.

2. Copy the generated .img file to /bootloader/system.img. Run:
$ sudo cp .img bootloader/system.img

3. Flash the image to the target board.

If the target board has already been flashed, reflash only the APP partition with the cloned image:
$ sudo ./flash.sh -r -k APP mmcblk0p1

If the target board has never been flashed, flash all partitions:
$ sudo ./flash.sh -r mmcblk0p1
