Dear Tord,

I never used dBUG - does it expect a special image format? Maybe you have to specify "binary" images or so?
"dl" command which only supports S-records. I made an image for loading at 0x20000 by the following command:
ppc_82xx-objcopy --gapfill=0xff --change-adresses=-0xFEFE0000 -O srec u-boot_20000.srec
Umm...
I loaded this with the dl command at 0x20000 and then it was programmed into flash by:
fp FF000000 FF035250 20000
I moved the boot jumper to the Low position and u-boot got up! Unfortunately, as soon as I tried to save environment variables (IP nad MAC-adresses) and rebooted, the system crashed. I fear that my objcopy tweaking might have been a little bit too hasty... : )
Probably. Try out what happens when you (re-) convert the _binary_ image into S-Records, something ike this:
ppc_82xx-objcopy --change-adresses=-0xFEFE0000 -I binary -O srec \ u-boot.bin your_image.srec
Best regards,
