Boot uboot-original-mtd0.kwb from USB into Pogoplug

My boot sequence is USB -> USB (uboot-original-mtd0.kwb on USB for recovery) -> mtd3 (openwrt) -> mtd1 (original Pogoplug)

If openWRT network is not accessible then I plug USB in with uboot-original-mtd0.kwb then it should boot into original Pogoplug.

I know this may be possible but can you help me to setup uboot parameters.

I found the way to boot openWRT on mtd3

setenv bootargs console=$console root=/dev/mtdblock3 rootfstype=jffs2
setenv partition nand0,3
fsload /boot/uImage
bootm 0x800000

And boot uboot-original-mtd0.kwb from USB into Pogoplug on mtd1

usb_init
ext2load usb $usb_device 0x800000 /uboot-original-mtd0.kwb
go 0x800200

Remember copy uboot-original-mtd0.kwb to USB root.

Install openWRT on mtd3

flash_eraseall /dev/mtd3
mkdir /tmp/openwrt
mount -t jffs2 /dev/mtdblock3 /tmp/openwrt
cd /tmp/openwrt
tar -xzvf openwrt-kirkwood-rootfs.tar.gz
mkdir boot
cp openwrt-kirkwood-uImage boot/uImage

Cheers

Cheers for this mate. I've been wanting to format mtd3 to jffs2 for some time but haven't been able to find out how. Turns out flash_eraseall does the jffs2 formatting when it erases it.

Hi,

I didnt understand the idea behind "go 0x800200" in the below command. why is it not "go 0x800000" like in other args?
"pogo_boot=if fsload uboot-original-mtd0.kwb; then go 0x800200; fi"

I couldnt boot to original Pogoplug parition. It always reboots as show below. Any ideas?

$ nc -l -u -p 6666

Notice that we load the image at 0x800000 but start running it from 0x800200. This is because the first 0x200 bytes of are the kirkwood image header, and the real executable starts after the header.

Thanks for the quick response. Can you give some pointers on why my dockstar couldnt boot to original installation? Any ideas to correct the problem?

Thanks
Ranganadh

mtd3 no longer contains pogo partition? did you flash_erase mtd3 in the process of installing ubifs?
