Then they should hire me :-)
The trick is very simple: with JTAG, write a program to RAM and run it.
That program connects somehow to a port (serial, USB or a custom
protocol over JTAG!) and reflashes the NAND.
Is that possible? Yes it is, because how would the upgrade application
upgrade your NAND flash with another version of PPC? So the CPU can
reflash
So, I'm not worried at all to kill the flash contents of my spare board.
That's where it is for and I'm really convinced that I can rewrite it.
The only point is that I don't have a proper JTAG device. So I'm toying
around with a Wiggler device :-(
Hopefully, I get that to work soon.
Bas.
