We have jetson nano booting from a memory card (128GB) and installed different software (like zed python and others). We brought more Jetson nano and instead of installing all the applications is it possible to clone this memory into another 128 gb memory and use it on the new system
Not cleanly, no. A bunch of things need to be reset from host name to ssh keys. You would have conflicts on your network and security issues. It’s easier to use Nvidia’s tools to generate a custom image that includes their first boot scripts. Read the L4T reference guide for how.
Edit: there is also a script in L4T home you can run to generate a nano image rather than fuss around manually with flash.sh
