u-boot with openwrt-kirkwood-uImage not uImage

I have updated my Seagate DockStar original u-boot code with Jeff's u-boot code from this Update uBoot on your Dockstar, GoFlex, or Pogoplug NAS page, I works just fine to boot OpenWRT firmware stored in an external USB partition. However, since the default kernel file name for an OpenWRT firmware for a Seagate DockStar is openwrt-kirkwood-uImage and not uImage, I have to either rename or create a link from openwrt-kirkwood-uImage to uImage; otherwise, Jeff's u-boot can't find the /boot/uImage kernel file to load. So, every time when I freshly compile an OpenWRT firmware for my Seagate DockStar, I have to rename openwrt-kirkwood-uImage to uImage and this has become a nuisance for me. For this, I would like to know if it is possible to change some u-boot environments so that the new u-boot will look for a /boot/openwrt-kirkwood-uImage instead of a /boot/uImage file.

Thanks.

fw_printenv usb_bootcmd
Look for the fsload command and modify the uImage filename accordingly.

Here is the output from fw_printenv usb_bootcmd and I don't see any fsload command:

Pogoplug:~$ /usr/sbin/fw_printenv usb_bootcmd 
usb_bootcmd=run usb_init; run usb_set_bootargs; run usb_boot
Pogoplug:~$
Pogoplug:~$ /usr/sbin/fw_printenv usb_boot   
usb_boot=mw 0x800000 0 1; ext2load usb  0x800000 /boot/openwrt-kirkwood-uImage; if ext2load usb  0x1100000 /boot/uInitrd; then bootm 0x800000 0x1100000; else bootm 0x800000; fi

Anyways, I took a liberty to dump the environment as shown below and ho knows you will be able to spot something.

It's already loading /boot/openwrt-kirkwood-uImage.

That's what I first thought so, but my Seagate DockStar still boots its original PogoPlug firmware and I have /boot/openwrt-kirkwood-uImage file on an external USB memory stick formatted as ext3. When I first flashed Jeff Doozan's u-boot to my Seagate DockStar, I had to create a link file, i.e. ln -sf openwrt-kirkwood-uImage uImage, so that my Seagate DockStar will boot into the external USB memory stick. Now, even I changed the environment back to uImage (from openwrt-kirkwood-uImage and created the linked uImage file), my Seagate DockStar no longer wants to boot into the external USB memory stick. Perhaps, I should reflash my Seagate DockStar with the same Jeff Doozan's u-boot again.

I have another Seagate DockStar confiugred with a 3-rd party u-boot where its arcNumber has been set to 2998. It perfectly runs with a self-built OpenWRT system on an external 1GB USB memory stick. I took out the USB memory stick and plugged in into the problematic Seagate DockStar flashed with a Doozan's u-boot and set its arcNumber to 2998. Then, I connected the problematic Seagate DockStar to a WindowsXP computer through its serial-console PINs with a serial-console cable and excerpted the boot process as shown below. Doozan's u-boot complained that the /boot/openwrt-kirkwood-uImage has a Wrong Image Format for bootm command. After that, it went to boot with the original (PogoPlug?) firmware.

Try a different usb stick.
For boot partition, try using ext2 instead of ext3.
The u-boot header for openwrt and debian kirkwood kernels may be different.

I did and still have the same problem.

IIRC, doozan's u-boot does have a support for EXT3. I wondered if it has a support for EXT4. If so, I sure don't mind to try.

When I replaced the original u-boot with Doozan's u-boot, set archNumber to 2998, created an EXT3 partition on a USB memory stick to hol dmy OpenWRT system, and created a /boot/uImage link to /boot/openwrt-kirkwood-uImage, my Seagate DockStar had no problem to boot into OpenWRT system on the external EXT3 partition. Since the doozan's u-boot recognizes uImage file and since OpenWRT only produces openwrt-kirkwood-uImage file, I thought to replace all uImage occurrence in the environment so that when I create a new external EXT partition, I can just copy the openwrt-kirkwood-uImage sans renaming it to uImage.

If they are different, then whey the doozan's u-boot was able to boot into my external EXT3 partition that contains OpenWRT system with /boot/uImage file before the modifications I made?

I tried to revert the environment by changing all openwrt-kirkwood-uImage occurrences to uImage and the doozan's u-boot now fails to boot into the external EXT3 partition that contains the OPenWRT system.

It looks like the only way to fix this problem is to restore to original u-boot which I have no idea how to proceed. Then, reflash it with the doozan's u-boot again. However, my preference is to hope someone who is knowledgeable in this matter to help me to fix this problem first.

It looks like I am on a dead end and would certainly like to get some help to restore the original u-boot. I noticed the doozan's u-boot update process created a /uboot-original-mtd0.kwb when my Seagate DockStar boots into its original Pogo firmware. The question is can I use this /uboot-original-mtd0.kwb file along with the instructions on Old: Restore old uBoot on mtd0 (last section) to restore to its original u-boot as shown below without bricking my Seagate DockStar? And, what about how to restore the environments to original settings?

/usr/sbin/flash_erase /dev/mtd0 0 4
/usr/sbin/nandwrite /dev/mtd0 /uboot-original-mtd0.kwb

Once I restore the original u-boot with the /uboot-original-mtd0.kwb file, I sure would like to try again to reflash my Seagate DockStar with doozan's u-boot.

OK. Now, I am back from vacation. I sure will appreciate if anyone out here can help me out to restore the original u-boot. This way, I can start all over again to install Doozan's u-boot.

IMHO it's the usb stick - try another one and not u-boot. Reflashing uboot is seriously overkill for the problem you are trying to solve.

I bricked my dockstar messing with fw_setenv which modifies mtd0's uboot. It took a while before I figured out how to JTAG and acquire the necessary tools to actually do it. Now the dockstar is hard to come by these days - if I can help it and I were in your shoes, I won't reflash uboot.

The external USB stick is no problem. It works with other DockStar unit. That's why I believe it is better to reflash with Doozan's u-boot (if possible) or original u-boot and then Doozan's u-boot.

I already have Debian booting from an USB pendrive formatted ext3 (on the nand I still have the original firmware). I'd like to install OpenWRT on another pendrive but I have no idea how exactly to prepare and copy the files.

Could anybody give me a hand?
Thanks

Do you have serial console access?

From the output of fw_printenv above, it looks like TS uses sda1 as root. Since openwrt doesn't use uInitrd and rootfs is on mtd2 by default, I am wondering if TS uses openwrt's ExtRoot support or simply unpacked rootfs onto sda1 - you could try that as a first option.
