Rescue System v2

@restamp,

Thanks restamp! forgot about that, fat fingers :) in any case, e2fsck won't check the mounted file system even if we try.

Hi bodhi,
I run the fsck , I used a new device , but never complete boot . I tried to change the env of uboot and now I no longer land in rescue .
Have a suggestion ?
I can repeat the flash from the beginning ?
Thanks

No need to. If you have saved the u-boot envs before changing, you can put them in uEnv.txt and boot. Once you you can boot Arch, then worry about saving them. If you did not save the u-boot envs then post back I will find the file and post the content here.

Your Arch kernel uImage is not good. So you can mount the USB drive on a different Linux box and regenerate it, or use a fresh rootfs on USB (extract the Arch tarball again to it).

I first submitted my request for help under the Macplug string since that is what I have installed. But I was trying to install the Rescue system over it so I am putting it here.
I ran into the following problem trying to update my Dockstar/Macplug to the rescue system. I eventually want to install the wheezy or squeeze but ran into similar problems and thought I would try something else to get out the current distro.

This script will install a rescue system on your NAND.
It will OVERWRITE ALL OF THE POGOPLUG FILES.

This script will replace the kernel on on mtd1 and the rootfs on mtd2.

This installer will only work on a Seagate Dockstar or Pogoplug Pink.
Do not run this installer on any other device.

By typing ok, you agree to assume all liabilities and risks 
associated with running this installer.

If you agree, type 'ok' and press ENTER to continue: ok

@Paul,

Probably your NAND is now hosed. If I interpreted the below correctly, u-boot was flashed, but there was error in writing the rescue image after that.

Writing data to block 0 at offset 0x0
Writing data to block 1 at offset 0x20000
Writing data to block 2 at offset 0x40000
Writing data to block 3 at offset 0x60000

Writing data to block 8 at offset 0x100000
..

./install_rescue.sh: line 270: /usr/sbin/flash_eraseall: not found
...
....

To be sure, don't reboot until you can install a known good u-boot from the command line. Since I believe you are doing this on a Dockstar or Pogo E02? it is always a danger to be locked out whenever you messing with NAND and see any error. Though in this case, if u-boot that was flashed is good, then you can recover with serial console.

Also, there was no indication that the mtd0 (block 0 to 7) was erased successfully before it was written. So I'd doubt that your u-boot can be used now.

Well . . .
I can still boot to the uboot prompt. Can I flash from there?
Yes, this is a dockstar. I had used a jtag on it a few years back but I'm pretty rusty.
I can read from USB and tftp too. So shouldn't I be able to load something?
Thanks.
Paul

@Paul,

If you can still boot to u-boot prompt then there is no need to reflash there. You can boot into Debian with USB roofs and decide what to do. And, you could run this rescue system with the latest u-boot I've released.

The part where it's needed is the rescue images. So the installation script should be modified as mentioned in Jeff's instruction:

Quote

The installer will check to make sure you're running the latest uBoot, so make sure you upgrade that before anything else. If you don't want to upgrade uBoot, you can comment out the check as long as you're not running the stock Pogoplug uBoot.

and in the script:

if [ "$UBOOT_DETAILS" = "" ]; then
  echo "##"
  echo "## uBoot is not up-to-date"
  echo "## Please install the newest uBoot and then re-run this installer."
  echo "##"
  exit 1
fi

bodhi,
Okay!
When I get a chance later I will set up a thumb drive. I had been searching for such instructions on the site but there are so many different things going on I couldn't sort out which I needed.
So, I want to set up a usb drive with the file system. I am guessing your signature has the necessary fs.
Thank you very much.
Paul

Yes. That's the latest rootfs, all NAND tools are already installed in it.

OK bodhi,

I made it back from the edge. Thanks. I setup the usb stick with the latest fs and typed boot at the uboot prompt. It found the fs and booted. I then did the rescue install. Now I am relearning hylafax to preserve my retro fax modem (you can still file medical claims via fax -- something you guys not here don't have to worry about!). Thanks again.

Hi,
Boot from a USB device (or a Debian NAND install) and run the following commands:

How can i boot from USB with my standard Goflex NET ?

i have an USB to Serial interface and i can log in by serial interface
i can start "dropbear start" but if i log in it is different to the serial login
some commands does'nt work...

To install rescue system, best to install Debian on USB first (you also need to adjust u-boot envs to boot USB, since you are booting with stock u-boot): http://forum.doozan.com/read.php?2,12096. And then install rescue system.


1. With that said, usually we just install latest Debian (mentioned above) and new u-boot: http://forum.doozan.com/read.php?3,12381. And boot from USB or SATA.

2. Read about the latest Debian rootfs/kernel and new u-boot here to learn more. You migh not want to run Debian from NAND since it is very limited comparing to USB/SATA.

I tried to update my Pogoplug E02 Pink with the files on here and now all I get is a yellow and green single flash on the network connector, I am assuming that it is bricked, nothing on the screen when I try "screen" or "putty" when using a JTAG connector and I don't seem to be able to talk to the box from Lubuntu in either program, I have been trying to find some definitive instructions on how to rewrite Uboot, I need to be guided from the getgo as I am very inexperienced in these things, anyone got any references or advice on how to (step by step) get this back up and running?
