can't flash nand

When you attempt to boot from SD, do you have to try twice every time and do
you get "unknown-block (179,2)" on the second try?  Just wondering.
To put your NAND uboot back into a "known" state, just use the latest
version of uboot that comes with Om2008.  Use this wiki page:
to find the instructions - there is a downloads page link off that page and
just use the latest version of uboot.

There's a subtle difference between the way you access the NOR uboot and the
way you access the NAND uboot, that I didn't catch the first time I read the
wiki and maybe you didn't notice either.  NAND uboot doesn't replace NOR
uboot; they both exist at once.  You access NOR uboot by pressing and
holding AUX first, and then power.  NAND uboot you access by pressing and
holding *power* first, and only afterwards (after 1-2 seconds, but before
the screen comes on) press and hold aux.  So, which one you see depends on
the order in which you press the two buttons.  It's possible your NAND uboot
is fine but that you were pressing the buttons in the NOR order.
