PogoPlug E02 install to NAND (no replies)

Sorry to bring an old thread back but its a Xmas holiday project :)

I've got my Pogoplug E02 up and running from the USB stick, but I can't for the life of me get it to flash to the NAND on the Pogoplug.

I'm not a Linux Noob but I would not call myself advanced, so at least I dont fear the CLI..

I've been following the thread - Linux Kernel 5.9.12 Kirkwood package and Debian rootfs (Thank you Bodhi for this!)

My attempts so far have resulted in a Pogoplug that rapidly flashes the LED Green then the LED rapidly flashes RED on boot without the Debian USB stick in place so I 'm sure its the process to flah the NAND that 'm getting wrong. Its not getting as far as being up and running.
Can anyone point me to a suitable thread with simple instructions so I cn atry and check what fiels should be in the flash memory or not??

Is it even possibel to do it on the memory the E02 has?

I'm also not sure what the U-Boot is on it, how can I tell what son the box itself? I flashed oit years ago and it has Arch on it., but I never used Arch and I'm slightly more conforable in Debian, and as I said its an Xmas project, so I wanted to update it and get it back to some form of usefullness...

Thanks in advance..
