Nano Image backup issue

Hi we use Nano eMMC version, found use the command ;
sudo ./ -r -k APP -G system.img jetson-nano-emmc mmcblk0p1
its didn’t work,please help.thanks

This would produce a sparse image, system.img, and a raw image, system.img.raw. The raw image is the one you can manipulate, but the smaller one can be used for flash. However, this is only the rootfs partition, it isn’t everything you need since there are other partitions used during boot.

Typically you would flash a new unit with the “-r” option to prevent overwriting the rootfs. Prior to this you would place either the system.img of backup, or the system.img.raw, with filename “system.img”, in the “Linux_for_Tegra/bootloader/” location, and then:

sudo ./ -r jetson-nano-emmc mmcblk0p1

This would result in all partitions being flashed, but the rootfs would be from your clone. The version of JetPack/SDK Manager used for this would have to match that from which the rootfs came from.

got it
