so i tried to use an image for plugpbx i found online and from the JTAG issued the following commands to try and boot off an external SD

setenv x_bootargs_root root=/dev/sdb2 rootdelay=15
setenv x_bootcmd_kernel fatload usb 0 0x6400000 uImage
saveenv reset

and now i get

scanning bus for devices... 6 USB Device(s) found
       scanning bus for storage devices... 2 Storage Device(s) found
reading uImage

** Unable to read "uImage" from usb 0:1 **
Wrong Image Format for bootm command
ERROR: can't get kernel image!
Marvell>>


how can i just tell the DP to go back to boot from the internal image that was working?

1. Is the first partition an ext rather than a fat? If so, fatload won't work, you need a newer command.
2. Surely you can just unplug the external SD?
Good luck

setenv x_bootcmd_kernel fatload usb 0 0x6400000 uImage

Try using 'ext2load' instead of 'fatload'. Dreamplugs with the code 0901 onwards have partition1 on the microSD as an ext2 partition.

Factory uboot settings for '0901' onwards Dreamplugs can be found here:
