uncorrectable error

Hi

I've tried to make my first steps on Mini2440 by using this tutorial
(http://narnia.cs.ttu.edu/drupal/node/131). Everything seemed to work fine
but when I've made a reset after the last command the kernel seems to be
loaded and I just get reams of entries like this:

Kernel panic - not syncing: Attempted to kill init!

Does anybody have an idea what might be happened wrong?

I have run thru his procedure, probably 100 times and haven't seen that
one.

You are using the u-boot, kernel and JFFS2 image that he refers to?

<mtd->read> might suggest that something has gone wrong in setting up the
partitions.

It is a 64M dev board you are using?

A test that you can run after loading the kernel.

  nand read 0x31000000 kernel 0x500000
  bootm 0x31000000

You should observe that the kernel gets further through the boot process,
possibly to the place where the file system would try to mount.

Then carry on with loading in the JFFS2 image.

Thanks for your reply. These output where printed after loading the kernel.
There where also some other output that I'll post next time I start up the
board.

PS: I use the Mini2440 128MB version with the u-boot-128MB image from this
page.

Mini2440 128MB version of the kernel?

The only process I could say works with that tutorial . . . is only using
the images he references on a 64M dev board.

I would verify that the u-boot-128MB image has sorted out the u-boot issue
that buserror refers to on his site.

If you using the 2.6.32.2 version of the kernel then there could be issues
trying to run the GPE JFFS2 rootfs image from that package.  As far as I
understand kernel modules have to be installed using the same version as
the kernel, if you expect everything to work properly.  He uses 2.6.29.4

Someone needs to rewrite that tutorial for 128M machines.
 
Good luck!

I am getting the same error, using the same process with a 128MB board, any
thoughts?

just to add, this is the kernel image:

u-boot prints:

@Vinicius Kamakura: links doesn't work. Could you provide correct links or
am I miss something? Did you make nand scrub and bbt ?
