Can't Get Kernel Image

Hey all,

I have a Dockstar that was running armedSlack just fine when I decided to give the Rescue System a try. The install seem to go fine, but on first boot it couldn't fine the kernel image. This is what I'm getting out of the serial port:

Is there anyway to recover this? I'm willing to go back to the factory firmware and start over if it's necessary

Hi all,

I made some progress on this, but still cannot boot a kernel image from the either nand or usb. I tried to reflash the original pogo software following these directions; http://plugapps.com/index.php5?title=Hardware:_Seagate_DockStar_Reflashing, but I get an alignment error. I have been able to install and boot armedslack by doing this:

Now download the Kernel and Slackware ARM installer via TFTP:

     Marvell>>   tftpboot 0x01100000 armedslack-current/uinitrd-kirkwood.img
     Marvell>>   tftpboot 0x00800000 armedslack-current/uImage-kirkwood
     Marvell>>   setenv bootargs console=ttyS0,115200 nodhcp kbd=uk root=/dev/ram rw
     Marvell>>   bootm 0x00800000 0x01100000

Anyway that as far as I get. I think that my problem is that I still have the rescue system environment variables. I have made several attempts to reflash Jeff's latest uboot, but cannot seem to permanently replace these environment variables. How would I go about completely erasing the environment memory and reflashing with the uboot.enviroment file? Can/ how would I do it from the uboot prompt

Thanks

The following variables in your environment are different from a normal environment:

bootargs
bootargs_root
bootcmd
console
usb_scan

(also the variables which are unique for your dockstar, but those are normal: cesvcid, ethaddr, ipaddr, serverip)

The "usb_scan" variable got truncated somehow. The variable should not end on "Found e". The usb_scan variable should list like this:

usb_scan=usb_scan_done=0;for scan in $usb_scan_list; do run usb_scan_$scan; if test $usb_scan_done -eq 0 && ext2load usb $usb 0x800000 /boot/uImage 1; then usb_scan_done=1; echo "Found bootable drive on usb $usb"; setenv usb_device $usb; setenv usb_root /dev/$dev; fi; done

Right now the boot loader doesn't get to that part though, because of the other variables. The way the rest of the scripts are set up, bootargs and bootargs_root are not needed, as they're set depending on the boot medium by the other scripts. These other scripts expect the console variable to be just the parameter value, not name=value as in your environment. That only affects the kernel console output, but you should still correct it. The console variable should be

console=ttyS0,115200

(not console=console=ttyS0,115200)

The real culprit is the bootcmd variable. That's supposed to refer to the other boot scripts, but in your environment it directly loads 3MB from the mtd1 partition and tries to boot that as a kernel image. If the kernel is bigger than 3MB, then that's going to fail. The bootcmd value should be

bootcmd=usb start; run force_rescue_bootcmd; run ubifs_bootcmd; run usb_bootcmd; usb stop; run rescue_bootcmd; run pogo_bootcmd; reset

To correct the environment, execute these commands at the uboot prompt:

setenv bootargs
setenv bootargs_root
setenv console 'ttyS0,115200'
setenv bootcmd 'usb start; run force_rescue_bootcmd; run ubifs_bootcmd; run usb_bootcmd; usb stop; run rescue_bootcmd; run pogo_bootcmd; reset'
setenv usb_scan 'usb_scan_done=0;for scan in $usb_scan_list; do run usb_scan_$scan; if test $usb_scan_done -eq 0 && ext2load usb $usb 0x800000 /boot/uImage 1; then usb_scan_done=1; echo "Found bootable drive on usb $usb"; setenv usb_device $usb; setenv usb_root /dev/$dev; fi; done'
saveenv

The setenv commands modify the environment in RAM, the saveenv writes the modified environment to flash memory. After writing the environment to flash, reset the Dockstar. It should then follow the expected boot sequence.

Johannes, thank's for your help. I made the changes as instructed. If reset the unit without a usb device plugged in I get the following.

However I can now boot from a USB stick. I have a usb stick with PlugBox Linux on it and it now boots up without problems.
So it looks like i can't boot to the pogo image.

Thanks

Yes!! success
After booting into PlugBox Linux, I ran the rescue installer script and now everything is working

Starting sshd: OK
Starting heartbeat LED...
