Creating Jetson Nano SD card image for distribution

Hi,
I tried using Linux for Tegra tools R32.5.1 to create image for SD card. However in terminal, in the tools folder and executing this command line “sudo ./jetson-disk-image-creator.sh -o sd_blob.img -b jetson-nano -r 300”, i get the following output:

May i know if i missed out on any steps?

hello michael.lai,

please refer to the failure as above.
may I know where did you execute this, what’s the environment setups.
thanks

Hi Jerry,

I checked that it was because I did not set Jetson Nano to recovery mode properly. Now I’ve checked lsusb from host terminal and i see the board is listed.

However now i face another issue, the output error is shown below:

sudo ./jetson-disk-image-creator.sh -o sd-blob.img -b jetson-nano -r 300

May I know what I can do to resolve this?

hello michael.lai,

may I know what’s your development environment?
you should execute jetson-disk-image-creator.sh script with the JetPack release image installed.
please refer to NVIDIA SDK Manager | NVIDIA Developer to install JetPack release image,
thanks

Hi

I’m using Ubuntu 18.04 as the host OS or development environment. I have installed the NVIDIA SDK Manager. Which packages for the host and target should I download for Jetpack 4.6?

hello michael.lai,

you should install JetPack release image on your desktop host machine.
the default image path as following,
~/nvidia/nvidia_sdk/JetPack_<version>_Linux_JETSON_<platform>/Linux_for_Tegra/

Hi,

I have downloaded Jetpack in the host machine using the SDK manager, extracted the zip file for Linux_for_Tegra and run the jetson-disk-image-creator script but it still gives the same error. Does this mean that I have to copy the root from SD card of Jetson Nano into the host’s Linux_for_Tegra/rootfs folder? If so then what is the best way to do this copy?

hello michael.lai,

that sounds incorrect, there’ll be script file there once you downloaded Jetpack by SDKmanager.
could you please have double confirmation. thanks
