eMMC size differ makes backup and restore fail

[yi-chia.lan]

Hi Nvidia,

On AGX orin , we can backup image and restore to the same module or to the module with same part-number.
But it will fail when restored module size larger then source module.

that measn:
if source module eMMC is smaller then restore module >> nvidia backup and restore works.
if source module eMMC size is larger then restore module >> restore will fail.

we are facing this problem due to Nvidia PCN
Is there any way to resolve this problem???

Hi,

Please try other clone methods below:

1. Enter this command on the device
   $ sudo sed -i "/\/boot\/efi/d" /etc/fstab

2. Follow “Cloning rootfs with initrd” in developer guide until "6. Copy the system.img.raw file from the USB drive the to host machine. " This will copy out the raw system.img.

3. Mount and replace this system.img.raw to another BSP rootfs. (For example. /mnt/rootfs)

sudo mount -o loop system.img.raw /mnt/rootfs 
cd ${path_to}/Linux_for_Tegra/rootfs/ 
sudo rm ./* -rf
sudo cp -p /mnt/rootfs/* ./ -rf

The method is to replace basic rootfs with your clone rootfs.

Thanks
