How to clone the EMMC content from unit A to unit B?

#1

for unit A, Can I use the maskrom tool to load extracted rz-udisk-loader.bin ,
(computer should detect a new storage device after the file is loaded）
then (in Linux)
sudo dd if=/dev/rdisk2 of=~/RadxaZero.img bs=4m

can I get the full cloned image of the EMMC?

then if I want to replicate the content on Unit B, I can flash the image using balenaEtcher, or simply
sudo dd of=/dev/rdisk2 if=~/RadxaZero.img bs=4m

Is it feasible? Can you confirm that?

#2

This should be fine if you are using our official images or Armbian, since we include bootloader in our installation image. Your commands only copy eMMC’s User Data Area, so if your distro doesn’t come with a bootloader (ex. Manjaro) you may need to back up boot partitions as well. Please refer to our boot troubleshooting guide.
