happy new year,

i try to update my sheevaplug. i compiled and flashed latest u-boot. it works fine.

But i have not the same luck with latest kernel.

According to this manual "http://shallowsky.com/linux/sheevaplug-kernel.html" i try to update the kernel.

But i get the following error message

what am I doing wrong yet..

every idea appreciated

[Confusticated]

From previous posts on the forum....

Globalscale privately forked both uboot and the kernel for the plug without getting an official machine ident,
they dreamt one up of their own. This means the machid (arcNumber) in Globalscale's uboot and kernel are invalid,
and only work with each other (this is what the plug was shipped with).

getting it wrong will cause the kernel to stop immediately

The mainline uboot command to set the machine id has since changed from 'arcNumber' to 'machid',
With an updated mainline uboot, to use the original Globalscale kernel from NAND you must specify
setenv machid XXXX

From your post....

Marvell>> bdinfo                                                               
arch_number = 0x00000831

U-Boot has been compiled for machine architecture id of 0x0831 by default (labelled as arch_number, a historical mistake).

My relevant u-boot-env:
arcNumber=2097
........
mainlineLinux=yes

These do nothing, as they are for older versions of U-Boot.

Using machid 0x692 from environment

This report from U-Boot shows it is using machine architecture id of 0x0692, as set in the environment variable 'machid', overriding the machine architecture id compiled into U-Boot.

Ensure that the U-Boot environment variable 'machid' matches the machine architecture id of the kernel, as

getting it wrong will cause the kernel to stop immediately

Search this forum for more details, use the guides on this forum.

[elvis61]

You are right. These are irrelevant

Marvell>> setenv mainlineLinux
Marvell>> setenv arcNumber
Marvell>> setenv machid
Marvell>> saveenv

> Ensure that the U-Boot environment variable 'machid' matches the machine architecture id of the kernel, as

i tought i done it with

setenv machid 692

because i got the following message if i don't define this env.variable

Is a 'RD-88F6281' kernel compatible with a SheevaPlug ?

I believe you need to use the last option with this kernel, that is
'Marvell Kirkwood (Flattened Device Tree)' don't forget that at boot time
you will need to pass the FDT complied from a 'dts' file for the SheevaPlug too.

Your version of U-Boot should support it, but you may possibly need to append
the FDT onto the kernel image to create a single boot image file.

I do not have (practical experience of) a SheevaPlug, you will have to RTFM unless someone else can help.

[elvis61]

Thanks for response..

> you will need to pass the FDT complied from a 'dts' file for the SheevaPlug too.

i don't know how doing this

if i set only machid i have the same behavior

i tried it with "Linux version 2.6.39.4" (because of i need no dts-files with this version) and have a stupid phenomenon.

Builroot:
  *** Linaro toolchains available for Cortex-A{5,7,8,9,15} and

     (1) Sourcery CodeBench ARM 2013.05
     (2) Sourcery CodeBench ARM 2012.03            
     (3) Sourcery CodeBench ARM 2011.09

i change between toolchains (1) and (3). If i compile first time with (1) it works. if i compile with (1) for the second time it doesn't work.

i go to toolchain (3) and have the same phenomenon. it is so to be crazy.

the precompiled version "http://www.xilka.com/sheeva/2.6/2.6.39/2.6.39.4/sheeva-2.6.39.4-uImage" works.

Is there a toolchain bug ??
