Installed ros and everything on NVidia board. Dd on to SD card and I have a bootable device.

Fiddle with boot config - fuck yeah.

I then just flash the new board.

Everything crashes FUCK. off and on again... Come on! phew

Ahhh but the flash should work, hmm choose another partition.

Everything is done YES I AM A HACKER. Unplug sd card, off and on again.

No response killed the bootloader, fuck me...
