Backup Your File System Image
As an edge AI platform, if you have made yourself a stable NRU development
environment. We would recommend you to make your own
File System Image
as your backup.
By following steps, you can create your own System Image on your Host
machine.
1. On target machine, clone RAW image from target to host machine via
Ethernet
# Example Code
# Please Update Variables based on Your Settings
sudo su
export HOST_IP=192.168.1.144 # Kaichu's Host Machine
export SYS_IMG_RAW=NRU-100_0930
# Stop File System
echo u > /proc/sysrq-trigger
# Low Level Backup of Target Raw (Raw Image will be stored under ~/
Folder of Host Machine)
dd if=/dev/mmcblk0p1 | ssh nvidia@$HOST_IP dd
of=$SYS_IMG_RAW.raw status=progress
2. On the host machine, convert RAW image to sparse system image
# Example Code
# Please Update Variables based on Your Settings
sudo -s
export HOST_IP=192.168.1.144
export
L4T_ROOT_J4_4=/home/nvidia/nvidia/nvidia_sdk/JetPack_4.4_Linux_
JETSON_AGX_XAVIER/Linux_for_Tegra
export SYS_IMG_RAW=NRU-100_0930
