[Gta04-owner] u-boot problems

Hello all,

I stopped goofing around with gyros and tried to install the latest 
kernel.  In order to take
advantage of devicetree, I needed to upgrade u-boot. so I got u-boot.bin 

and tried to flash it with

flash_eraseall /dev/mtd1;
nandwrite -p u-boot.bin /dev/mtd1

This booted to a white screen, so I made an sd card of the hw-validation 
image and booted from that, got a red screen and u-boot was restored.

This time I got u-boot.flash from the same site and tried to flash 
that.  My gta04 is now just showing a black screen.  I do see 'Das 
U-Boot' if I boot while connected to USB, so I dont think I broke any 

Am I correct that I need to load u-boot over serial now?  I don't have a 
serial cable and shipping would be prohibitively expensive to order one 
from GDC.  Is it correct that I need these: 
and this: 
(along with some more wire and a db9 connector) to make one?
