OE on Kontron eb425

OE on Kontron eb425

[Stefano Cailotto]

Hi all, 
I'm trying to build something usable for a kontron eb425 board, based on an
intel ixp425.
I tried to compile using a generic ixp4xxbe, but when loading, the kernel
stops after uncompressing reporting a CRC error.
It seems that Kontron EmbeddedLinux development kit performs something on
the kernel before making zImage in order to load it in a specifed memory
location.
I'd like to use OE, anyway, so my questions are:
1) has anyone faced my same problem (possibly with positive results)?
2) is there away to "port" kontron configuration inside OE?I'm looking to
understand how...

Thanx, 
Stefano

There are some IXP42x users on OE, mostly for the NSLU device from
Linksys/Cisco, the Intel dev board (IXDP425) and some custom boards,
but I have not see the Kontron board yet.

With the reported problem, it would help if you understand or at least
could tell where to find the details on the boot loader.

Ideally, you would want to boot loader to be buildable from source
instead of relying on some binary on flash.

Regards,

Leon.

A very important detail is which MACH ID the bootloader passes via ATAG.

Hello Leon, 
I've extracted kontron modifications with a diff between their shipped
kernel and a fresh one.
I don't know if it is possible to flash even the bootloader...
Looking a bit into source code, there are several kontron patches both for
drivers and kernel boot.
I'm trying to KOntron kernel into OE using Kontron toolchain, but without
success..
