You can open the dreamplug (loss of warrenty!), remove the micro sd card and put it into a card reader in your pc. Then edit the fstab file back to its original state.

Thank you for this posting. It works here on the Dreamplug as well with Kernel 2.6.38.8. 2.6.39.2 doesn't have a proper vserver patch yet.

vserver-stat works with this Kernel version as well. I'm using util-vserver-0.30.216-pre2981.

Btw: My USB went dead after trying the .33.8 kernel. Is something seriously broken in the new kernels or is it just a coincidence?

If you find out anything, please report. I'm having the same problem here with my guruplug server plus. Sad

Try a "usb start" in uboot. If only one USB device is reported, you've got a broken plug (like mine). Sad

@popon: Well, what you are doing is booting the rootfs from the microsd card. How this can be achieved is explained very early in this thread. The problem is getting the kernel from inside uboot out of the microsd filesystem (and accessing the microsd card from uboot at all).

root=/dev/mmcblk0p
This one is wrong. You need to change it to root=/dev/sdb1 (1 if your rootfs is on the first partition, 2 if on the second and so on) and it should boot. If it doesn't, you need to add rootdelay=10 to give the usb time to spin up.

Anyone knows the best way to contact globalscale? Since this is a major issue on the plugs, they should give a statement on that, shouldn't they?

Hmm.. I only tried ext2 partitions of different size on different storage devices (built-in sdcard, external usb hdd, external memory sticks) but u.boot would only find the internal sdcard reader (i think) but is unable to load it:

I also tried to add the "UBI" stuff, which I think should be able to access the SD card (not sure, though). But that wouldn't link (missing reference to rb_first and other symbols, apparently stuff in include/linux/rbtree.h, no idea what that is).
The UBI stuff is only usable on mtd devices, which the microsd card isn't. So you only need the UBI stuff for the internal flash of the guruplug.

I've only managed to boot a kernel from an usb stick plugged into the guruplug and formatted with the fat filesystem (fat because the vanilla u-boot from plugcomputer.org doesn't contain ext2 support):

Code:
usb start
set bootargs 'console=ttyS0,115200 ro root=/dev/sdb1 rootdelay=10'
fatload usb 1:1 0x06400000 uimage-guruplug
bootm 0x06400000

Trying to create a fat partition on the microsd card, it isn't recognized by the u-boot plug. Then it actually should read
Code:
...
root=/dev/sdb2
...
fatload usb 0:1 0x06400000 uimage-guruplug
...
For that test I partitioned the first partition of the microsd card to be an 100MB fat partition and the second partition to be the ext3 holding the rootfs. Unfortunately the u-boot cannot read the fat on partition 1:
Code:
Marvell>> fatls usb 0:1
Device NOT ready
   Request Sense returned 02 3A 00
** Can't read from device 0 **

** Unable to use usb 0:1 for fatls **
whereas the fatls on the external usb stick succeeds:
Code:
Marvell>> fatls usb 1:1
  2688588   uimage-guruplug
  7173509   uimage-guruplug.vmlinux

2 file(s), 0 dir(s)

Yes, I think having the Kernel on the microSD card would be the optimum that I'm working towards as well. Hoperfully the globalscale guys update the wiki with a tutorial how to boot the kernel from the microSD card. Smiley
14  General Category / General Discussion / Re: GuruPlug Server Plus Boot from microSD on: May 14, 2010, 05:50:29 AM
I didn't try booting a kernel from the microSD card yet. What I did do here is to have the kernel in flash and make the kernel boot the rootfs from the microSD card by setting the environment in u-boot to:
Code:
x_bootargs_root=root=/dev/sdb1 rootdelay=10
15  General Category / General Discussion / Re: GuruPlug Server Plus REBOOT!!! on: May 14, 2010, 05:48:20 AM
I've got the same issue. If I plug in the LAN cable to the second port before booting the plug, it stops booting or reboots after the Bluetooth: vendor=... message.

I'm using the latest u-boot, kernel and rootfs from http://plugcomputer.org/index.php/us/resources/downloads?func=select&id=14

If i plug in the cable after the guruplug is up and running, everything works fine (at least for the minutes, that I've testet it, after reading this topic).
