I've successfully written a new NAND image to my 7260 using
serialblaster.
I'm having trouble writing the bootloader and redboot however. Here's
what I'm doing ...
The first step is to send ts7260-nand2k-default via xmodem. This works
fine and I write it to eeprom.
The second step I send tsbootrom-7260.bin via xmodem. This also works
fine and then fis write it.
I then remove the jumper from jp1 and boot normally. This message
repeats itself over and over ... the tsbootloader never loads:
