GoFlex Home: booting the original firmware

I have installed the new u-boot using Jeff's install_uboot_mtd0.sh in my Seagate GoFlex Home without any problems. I have also installed Debian following davygravy's instructions in http://forum.doozan.com/read.php?2,7806. However I only have a few moments everyday to work in the unit (while is not serving files to the family) and hence, I need to boot the original firmware until my Debian installation is fully configured and working. According to http://projects.doozan.com/uboot/, it can be done by simply unplugging the USB drive and rebooting. But it doesn't work in my case. I plugged a serial cable to the GFH and here is the output:

I was able to boot the original kernel by running the original uboot environment commands:

GoFlexNet> setenv console2 'console=ttyS0,115200'

but then it hangs. I tried setting all the original environment variables before running those commands without any success.

I can revert to the original uboot but I would like to have a way to boot the original firmware from the updated uboot.

Does you have any idea on what is going wrong?

Thanks and sorry for this long post.

I don't have a detail instruction written up. But the idea is:

- Boot into Debian.

- check the mtd partitions
#fw_printenv mtdparts

- The original uBoot image uboot-original-mtd0.kwb should have been copied to the top directory of rootfs mtd partition (mtd2). So you can mount this while in Debian and make sure the file is there, and not corrupted (looks like this file is there, according to your log, but it's not usable).

- find the original uBoot fle, and copy it to the top directory of this root files system. And then umoun this rootfs.
- shutdown and reboot wihtout the USB stick.

The mount command is something like below. This is only an example, please make sure you find the correct commands before trying.
mount -t jffs2 -o rw /dev/mtdblock2 /mnt

Hi Bodhi, thank you for your answer.

I have tried the solution you proposed but I couldn't mount the nand. The syntax is correct but when I try to mount any of /dev/mtdblock* it results in a long list of errors. For instance:

mount -t jffs2  /dev/mtdblock0 kk

I have tried with all them with the same result. cat /proc/mtd returned:

mtd0: 00100000 00020000 "u-boot"

mtd2: 02000000 00020000 "rootfs"
mtd3: 0db00000 00020000 "data"

I have also tried stupid things as to create a jffs2 filesystem only with the uboot-original-mtd0.kwb file and write it to mtd2 (I made a backup before). When rebooting, I got

...
### JFFS2 loading 'uboot-original-mtd0.kwb' to 0x800000
Scanning JFFS2 FS: . done.
### JFFS2 load complete: 524288 bytes loaded to 0x800000
## Starting application at 0x00800200 ...

and a nice blinking red led.

I rewrote the backup of the nand back to mtd2, wrote the original uboot to mt0 and rebooted.
It resulted in an error while reading the nand and I had to flash the original seagate firmware again.

So, I'm again in the same place. Any other idea?

Thanks

Ok. Instead of trying to make the Pogo OS work, you could use Davy's rootfs to run the GoFlex Home temporarily. I don't remmeber it has samba already installed. If not, it should be simple to install it. This could serve as temporary file server for the family until you get your own Debian rootfs set up.

OK, I will take that approach. However it is a pity not to be able to make uboot to run the original firmware.


Thank you for your help.

I'm actually facing pretty the same issue as teosoft. I have installed Jeff's uBoot on my Goflex Net and booting debian from USB works fine. But I also do want to use the Pogo OS/original firmware as well (without necessarily having to restore the original uBoot on mtd0). As far as I understand this should be possible based on Jeff's description. Thus I consider that I'm facing a bug!?

My uBoot output looks like this:

I have also mounted the JFFS2 mtdblock2 via my debian installation. I have copied away uboot-original-mtd0.kwb file from the root directory and have done a file compare with a version downloaded from the inet, which turned out to be identical. So even though I face "error reading nand", I assume the uBoot should be intact and loaded correctly.
