My Dockstar has both Rescue System and readonly emdebian on NAND installed. Both systems worked well before. Also I used rescue system to build a couple of USB flash (4GB) Debian Lenny system, because I need large space to run Asterisk. Today, I used Rescue system to build another Debian Lenny on flash drive. After complete installation, I typed “Y” to restart the Docksatr. However, It stuck there and I can not get its IP address through router. If boot it from flash drive or just from Rescue system (without flash drive attached) , the light goes: green flash --> orange solid --> green solid, then keeping solid green light forever. Did anybody encounter this problems? I need your help. Thanks.

Configure netconsole and watch the boot log. It should show you where things are going wrong. If you're still having trouble, post your netconsole log.

Thanks, Jeff.
I don't know if my Dockstar is okay to use IP address.However, the Dockstar's IP is not showed on my routewr and my PC's IP address is displayed on my router. Meanwhile, I can not access the Dockstar with Putty. Can I get the netconsole log in this situation?

Yes, you can still use netconsole. With netconsole, you tell the Dockstar what IP address to use, instead of letting it get one from your router.

Hi, Jeff,
1. How to do "With netconsole, you tell the Dockstar what IP address to use..."? At PC side?
2. where to apply these below commands ( I mean how I can apply these commands to Dockstar because SSH doesn't work)

fw_setenv serverip 192.168.1.2
fw_setenv ipaddr 192.168.1.100
fw_setenv if_netconsole 'ping $serverip' 
......

I'm sorry, I misread your original post.

It sounds like your Dockstar may be getting hung up while attempting to boot from your nand installation. If that's the case, you can force it to boot the rescue system by creating an empty file named 'rescueme' on the root of your ext2 formatted USB drive. Make sure that drive is the only thing connected to the Dockstar and then reboot. With any luck, that will get you into the rescue system and you can use that to configure netconsole.

Hi, Jeff,
You are right! The Dockstar booted successfully from Rescue System with the USB drive attached. Without USB drive attached, Dockstar still doesn't work. The netconsole log is below:

If attach a USB drive that has Debian installed before, the Dockstar still doesn't work. The netconsole log is:

It doesn't look like you have any problems with your uBoot config. It's loading and booting the system on nand just fine. The line

Starting kernel ... 

is where the kernel takes over and stops sending netconsole messages.

Unfortunately, something happens after the kernel takes over. The default kernel doesn't support netconsole, so unless you attach a serial cable it's going to be very difficult to diagnose. The fact that the LED turns green usually means that everything booted properly and the network is up and running. Are you sure the device isn't just getting a different IP address?

The good news is that you can use the rescue system to get to your ubifs partition:

ubiattach /dev/ubi_ctrl -m 3
mkdir /tmp/ubifs
mount -t ubifs ubi0:rootfs /tmp/ubifs

You can try altering config files to see if you can get it to boot, however, without a serial cable that's probably going to be very frustrating work.

The Debian flash drive does not boot because uBoot tries to boot from nand first. If you'd like to just go back to booting from the flash drives, you can disable your nand partition by mounting it as above and then renaming /tmp/ubifs/boot/uImage to something else. This way uBoot will fail when trying to boot from nand and will then try to boot from the USB drive.

Got errors:

rescue:/# ubiattach /dev/ubi_ctrl -m 3
libubi: error!: cannot open "/dev/ubi_ctrl"
        error! 2 (No such file or directory)
ubiattach: error!: cannot attach mtd3
           error 2 (No such file or directory)

Looks like you'll have to manually create the ubi_ctrl device. Try this

mount -o remount,rw /
mknod /dev/ubi_ctrl c 10 62
mount -o remount,ro /

ubiattach /dev/ubi_ctrl -m 3
mkdir /tmp/ubifs
mount -t ubifs ubi1:rootfs /tmp/ubifs

Hi, Jeff,

The Dockstar works now. I appreciate you help.

I'm glad you got it fixed. Out of curiosity, did you figure out what was wrong with your nand partition? Or did you just switch to USB booting?

"...you can disable your nand partition by mounting it as above and then renaming /tmp/ubifs/boot/uImage to something else"...

After disabling the nand partition, both Rescue System and USB booting work correctly. It's enough to satisfy my work. Thank you again, Jeff!

By the way, can we duplicate the bootable USB drive (including ALL application files in it)?

There's a short guide for that on http://www.rudiswiki.de/wiki/DockStarDebian

Cheers,
Wolfgang

I use:

tar \
--exclude=/lost+found \
--exclude=/tmp \
--exclude=/sys \
--exclude=/proc \
-zcf /tmp/backup.tgz

Just remember to re-create the tmp, sys, and proc directories if you ever extract it to an empty drive.

Thank you, Wolfgang and Jeff! You save my time.

I followed the guide on http://www.rudiswiki.de/wiki/DockStarDebian and have duplicated my workable USB drive.

Hi Jeff, I got into similar situation (Dockstar stopped booting with initramfs prompt if an external drive is attached). I found out I need to move the USB external drive (not the bootable one) to the USB socket next to RESET button, then my Dockstar can boot up fine again.
