messed up uboot var prevent booting on sheevaplug (bad magic number)

Hi,

i received my sheeva plug lst week, and while i was looking into the boot change boot device, and long story short, all my ubbot var were changed to this :

Nice find !

But i still got the same error.

Gonna try to reinstall debian as soon as possible, but my internet is broken at the moment.

Thanks anyway

From the PLUGWIKI:
     Addresses (0x0) - PlugWiki  <--- Click here

RAM Memory use
0x800000 (8 MB)

This is the default RAM address into which the kernel image is loaded (on the SheevaPlug) for execution.

Why this number? Because 0x0 - 0x800000 are reserved for U-Boot. (Really, look at the messages U-Boot prints when starting, before the kernel is copied.)

I've tested loading the kernel into other RAM addresses, and there does not seem to be a problem. But, if the memory manager is trying to handle two block (one above and one below the kernel), there might be a minor amount of extra work required. Generally, I'd suggest loading the kernel at the low end (0x800000) and allowing all the remaining memory to be managed as a single block.

With that in mind, it is very common to also see this address used in the commands fatload, ext2load, or tftpboot as a safe place to load an image into RAM temporarily before writing it to Flash.

Maybe your uImage in 0x800000 is hosed, you can rewrite a clean one with these instructions:

Good Luck,

I've tried the first step (without writing the uimage to the nand, just reading it) with the uimage from here :
http://www.cyrius.com/debian/kirkwood/sheevaplug/install.html

But it's stuck after

Code:

Did you upgrade the Uboot?

http://www.plugcomputer.org/plugforum/index.php?topic=6057.0

Unfortunately, anyone else that takes the link from the Debian Linux page will also see the recommendation to upgrade u-boot.

http://www.cyrius.com/debian/kirkwood/sheevaplug/install.html

"You have to upgrade the u-boot boot loader before you can install Debian. "

[Mwoua]

Same after upgrading.

Maybe my whole Debian install is fucked up and i need to reinstall everything (i've just used the uimage from my link with the method you gave me)

Maybe i should try to use the uInitrd aswell (but my internet is still broken and i guess it needs it), i dunno what the uinitrd is, im kinda new to linux

[Mwoua]

Hi again.

I've finally gotten my internet back, so i tried to fix my sheevaplug

I've installed a clean Debian install on SD card following this :
 http://www.plugcomputer.org/plugwiki/index.php/Installing_Debian_To_Flash

Tried putting in on the nand, and boot on it, but it doesnt work
i think that my var are not good

Here is what i getd
