Jetson TX2 Cloning

Hello;

How can I get a clone of tx2 and used it to flash?

Can you direct me to somewhere, I am unable to find something much.

There may be differences depending on release, but start here:

When you go to restore you’ll want to restore to the same release version the clone is from.
