Trouble installing Jetpack 4.4 on nano initial model


I am using the before model.
I am having trouble installing Jetpack 4.4.
I am installing L4T but it does not work.
Please tell me how to solve it.

Thank you.

If you are able to get a serial console log, then this is the best way to see what is going on. Quite often the system boots, but video configuration fails (which is mistaken for a failed boot). Serial console gets around this. See:

Or if the actual flash failed, then this too is useful.

Normally you would also have to complete the first boot setup of an account, but if video is not working, this is a problem.
