Cloning Jetson Nano emmc

Autonomous Machines Jetson & Embedded Systems Jetson Nano
1

Hi,

I want to clone my Jetson Nano production module. I followed the steps from Jetson/Clone - eLinux.org.

Command use to create the image:
sudo ./flash.sh -r -k APP -G backup.img jetson-nano-emmc mmcblk0p1

The error I get is the follow:
[ 1.7615 ] 00000004: Failed to get an accessor of secondary boot device

Is it possible to mount the Jetson as storage on the host pc and make then an image?

Thanks
Dieter

hello dieter.vanolmen,

it’s known issue of r32.3.1; please refer to post #21 from Topic 82908, and update nvtboot binary for verification,
thanks

Thank you! Just want to mention that linked solution worked for me too.

Question: once we backup nano production emmc, how can we restore in nano development SD card? I tried it and it gets stuck during boot.

hello razvan.grigore,

please note that, while you using below commands to backup an image,
$ sudo ./flash.sh -r -k APP -G backup.img jetson-nano-emmc mmcblk0p1

this only clone APP partition into backup.img, there’re still other necessary partitions you’ll need to boot-up Nano platform.
you may also refer to Nano’s quick start instruction page, please check Write Image to the microSD Card session.
for example, please check the SD-card image from download center, which differ from the cloned image.
thanks
