Jetson/AGX Xavier Alternative II For Cloning

First, stop disk at Xavier:

echo u > /proc/sysrq-trigger

Second, take raw image:

dd if=/dev/mmcblk0p1 of=/path/testimage.raw

 Moreover, the image could be taken over the network e.g. using one of two methods below:

dd if=/dev/mmcblk0p1 | ssh user@hostpc dd of=/data/testimage.raw

sender: sudo dd if=/dev/mmcblk0p1 | netcat 

reciever: netcat -l -p > your_image_file

Third, make sparseimage [at Host PC]

./mksparse -v --fillpattern=0 ~/testimage.raw system.img

Fourth, deploy the sparse image to other devices:

sudo ./flash.sh -r jetson-Xavier mmcblk0p1
