Generate and load custom image Jetson Nano 16 GB eMMC

[colablabo]

Hello,
I have a Jetson Nano 16 GB eMMC (not micro-SD) with a custom program installed with all the required libraries and files. I have others Jetson prepared, and I want to install the same image in these new modules. So I want to generate an image of the system in a pendrive USB and load that image on the other modules. But I can’t find any program or script to do it properly.

I installed the program in the first Jetson by sdkmanager and used apt and python to install all the other libraries, but I want to do it more simply, just generating the image.

Thanks so much for the help
Greetings

Hi colablabo,

Are you using the devkit or custom board?

So I want to generate an image of the system in a pendrive USB and load that image on the other modules. But I can’t find any program or script to do it properly.

You could refer to the following instruction to flash to a USB drive.

I installed the program in the first Jetson by sdkmanager and used apt and python to install all the other libraries, but I want to do it more simply, just generating the image.

For this use case, you could just clone this all ready(with required packages/libraries installed) module and restore to other modules.

Hi,
I will leave a basic tutorial of what I just do:
Execute everything on an external Linux PC.

1. Enter on this link:
   https://developer.nvidia.com/linux-tegra
   a. Select the Jetson Linux Archive of your board, you can check it by executing this on your Jetson
   device: head -n 1 /etc/nv_tegra_release
   b. Download the Driver Package (BSP)
   c. Download the Sample Root Filesystem

2. Execute this inside the Download folder:

tar xf ${L4T_RELEASE_PACKAGE}
cd Linux_for_Tegra/rootfs/    
sudo tar xpf ../../${SAMPLE_FS_PACKAGE}  
cd ..

3. To copy the image of your Jetson into the PC, connect the microUSB in your Jetson and PC and power the Jetson in
   recovery mode. Execute this:

sudo ./flash.sh -r -k APP -G jetson.img <board> mmcblk0p1
sudo cp jetson.img bootloader/system.img

4. To paste the img generated into a Jetson, connect the microUSB in your Jetson and PC and power the
   Jetson in recovery mode, if the Jetson contains any information (the target board has already been flashed).
   Execute this:

sudo ./flash.sh -r -k APP <board> mmcblk0p1
sudo ./flash.sh -r <board> mmcblk0p1

If not just execute this:

sudo ./flash.sh -r <board> mmcblk0p1

• change ${L4T_RELEASE_PACKAGE} and ${SAMPLE_FS_PACKAGE} for the names of the downloaded archives
• change <board> to your device name following this table: https://docs.nvidia.com/jetson/archives/l4t-archived/l4t-3261/index.html#page/Tegra%20Linux%20Driver%20Package%20Development%20Guide/quick_start.html#wwpID0EAAPNHA

Thanks so much for the answer
