I took backup of AXG using below command
sudo echo "u" | sudo dd of=/proc/sysrq-trigger sudo dd if=/dev/mmcblk0p1 | ssh email@example.com dd of=/home/user/xavier-image.raw
For restoring I needed flash.sh, since my host machine was fresh ubuntu 18, I didn’t had any previous files which were used to flash AGX. So I had to install SDK manager on host machine. I was still missing flash.sh, so I had to flash AGX with JETPACK 4.5.1 from SDK manager. After installing JETPACK on AGX, I had all the files which I need to restore my backup image file.
I used below command to restore my backup image. I don’t know exactly which OS my backup image is, but surely it can’t be JETPACK 4.5.1. I had my old AGX flashed more than 1 year ago.
cd /home/nvidia/Downloads/Xavier/Linux_for_Tegra ln -s /home/user/xavier-image.raw bootloader/system.img #( I also tried below command to convert raw to img) # sudo bootloader/mksparse -v --fillpattern=0 /home/user/image.raw /bootloader/system.img cd /home/nvidia/Downloads/Xavier/Linux_for_Tegra/ sudo ./flash.sh -r jetson-xavier mmcblk0p1
Flashing was successful, but I don’t see any screen. I have tried different ways disconnecting hdmi before the boot, but still I don’t see my system starting up. I have attached log of flash and boot.
Please help me to restore.
