It sounds like maybe you don't have the MBR boot code on the card.
I've created some files on our ftp site to assist you in reflashing your
board:
ftp://ftp.embeddedARM.com/ts7800/reflash/
The flash7800 script is a modified version of the script we use to flash
boards at the factory. You may want to look over and edit the script
before running it in case some of the steps are/aren't needed. For
instance, you may need to uncomment and tweak the first line if the nand
flash drivers aren't loaded yet on your board. If you suspect you still
have a working root filesystem you may also want to comment out the parts
dealing with untarring the root filesystem so as to save a lot of time.
