Linux Images (ROCK64)

[gene83]

I need 2 things:
1. a piclone equ for the rock64 running the aufan stretch minimal install? Or do I have to take the micro-sd to another machine to make a backup sd card?

2. Where can I find a tutorial describing how to update the u-boot kernel, or better yet, an installer that will update the actual boot to use a locally built RT kernel?

Thanks all.

Cheers, Gene Heskett
