That's what I did. Longer term I'd like to figure out why it doesn't
With regards to using LDR and putting u-boot in a LINUX block I confess
I didn't think of that originally, but I'd rather be running code that
we understand rather than having to spend more time reverse engineering
the Amstrad block format and where things need to go in the NAND to make
I have a solution that seems to work (except for u-boot being quite slow
to read from NAND; need to sort the ready bit support out) and as soon
as I get over the cold I've been dying of all weekend I'll sort out a
release for people.
