Thanks, Steve.

When I erased NAND I must have truly clobbered something, because it is 
not booting from an SD card I thought was good.

In a minicom window, this is what I see:

A second SD card has a 512 Mb FAT partition and an empty EXT3 /dev/sdb2 
partition for rootfs. That card was the one I was using to update 
x-load, u-boot and uimage. It had a boot.scr script to do these updates, 
and the board did boot from the fat partition and execute that script. 
That is what clobbered me. Now, when I power on the board, the GPIO21 
LED on the Summit board (which is between the HDMI and USB host 
connectors) turns orange. It might have happened as a result of the 
script I used.

On the good side, I was just able to compile kermit version 9 on my 
Fedora 14 box, so maybe I can succeed with re-flashing the NAND.
