Kernel panic - not syncing: No init found.

[sshcherbakov]

Hi all,

I have tried to reflash my SheevaPlug today. This is a simplest (factory?) SheevaPlug version.
I have followed thoroughly the manual for reflashing using NFS found on a SheevaPlug CD.

I have also set up exact environment as described here:
http://www.newit.co.uk/forum/index.php/topic,134.0.html

I cannot boot afterwards though.
I'd appreciate any idea regarding what could be a reason.
Here is a log a an error message at the end:

I have tried to reflash my SheevaPlug today. This is a simplest (factory?) SheevaPlug version.
I have followed thoroughly the manual for reflashing using NFS found on a SheevaPlug CD.

I have not been able to succeed with the instructions on the CD for NFS recovery.

The best way is to use the installer:

http://www.plugcomputer.org/index.php/us/resources/downloads?func=select&id=5

By the way, I sent a reply to the e-mail that you sent; my replies (I tried twice) bounced with "550 No such user - psmtp".

Thank you, Marcus, I received your e-mail.
The CD manual worked for me very well. I started from chapter 3 of the "Writing Jaunty Filesystem", since we have already NFS/TFTP/DHCP infrastructure.
After I boot from NFS the output of the cat /proc/mtd is different from the parameters described in step 4.e though.
Here is what manual says:

Code:

set console 'console=ttyS0,115200 mtdparts=:0x100000@0x000000(uboot),0x300000@0x100000(uImage),0x1fc00000@0x400000(rootfs)rw'

and here is cat /proc/mtd output after booting:

Code:

mtd0: 00100000 00020000 "u-boot"
mtd1: 00200000 00020000 "uImage"
mtd2: 1fd00000 00020000 "root"

As you can see the sizes and offsets are different. So it looks like the those parameters doen't have influence during NFS boot?

Further in the manual stands how to switch environment back to enable booting from /dev/mtdblock2:

Code:

setenv bootargs 'console=ttyS0,115200 mtdparts=nand_mtd:0x100000@0x00000(uboot),0x300000@0x100000(uImage)ro,0x1fC00000@0x400000(rootfs)rw root=/dev/mtdblock2'
setenv bootcmd 'nand read.e 0x800000 0x100000 0x300000; bootm 0x800000'

This is wrong in regards to what the /proc/mtd has showed me.
So, after I fixed sizes and offsets like this:

Code:

setenv bootargs 'console=ttyS0,115200 mtdparts=nand_mtd:0x100000@0x00000(uboot),0x200000@0x100000(uImage)ro,0x1fd00000@0x300000(rootfs)rw root=/dev/mtdblock2'
setenv bootcmd 'nand read.e 0x800000 0x100000 0x300000; bootm 0x800000'

I could boot properly!
Phew..

Now we are fighting with reflashing a UBIFS configured unit, so further questions coming soon

Btw, does the jffs2 file system image supplied on CD can be used with UBIFS configuration?
We are seeing some strange problem booting UBIFS unit after we flashed jffs2 partition. It looks like the system  doesn't recognize the jffs2 fs format and expects something else?

Anyway, thanks for support!

I got as far as the final step, but couldn't get a combination of settings that worked.

Now we are fighting with reflashing a UBIFS configured unit, so further questions coming soon

Btw, does the jffs2 file system image supplied on CD can be used with UBIFS configuration?
We are seeing some strange problem booting UBIFS unit after we flashed jffs2 partition. It looks like the system  doesn't recognize the jffs2 fs format and expects something else?

Anyway, thanks for support!

Use the installer. That's the way to configure a plug for UBIFS. If you want to use a different rootfs, you could extract the jffs2 contents, recompress as rootfs.tar.gz, and use in place of the rootfs used by the installer. (You can also use this technique to install Debian or Fedora).

Don't make it more complicated than you need to; use the installer.
