unrecognized/unsupported machine ID

Hello,

I compiled linux 2.6.35.7 stable release from kernel.org, loaded it to RedBoot and got this:

EM-7210 (RAM mode) 2005-12-22
== Executing boot script in 5.000 seconds - enter ^C to abort ^C
RedBoot> load -v -r -b 0x01008000 -m tftp zImage-20101005 /
Raw file loaded 0x01008000-0x011e7187, assumed entry at 0x01008000 RedBoot> exec
Using base address 0x01008000 and length 0x001df188 Uncompressing Linux... done, booting the kernel.

Error: unrecognized/unsupported machine ID (r1 = 0x00000147).

Available machine support:

ID (hex) NAME
000004bc Lanner EM7210

Please check your kernel config and/or bootloader.

The machine I'm trying to execute linux on is Intel SS4000E, which should identify as Lanner EM7210.
Linux 2.6.25.20 runs fine.

Hi,

default redboot is using the wrong machine id (iirc iq31244 machine id) so you have to use things like devio to modify r1 register before booting the kernel. I use a script doing roughly that :

(
devio 'wl 0xe3a01c04,4' 'wl 0xe38110bc,4'
cat arch/arm/boot/zImage
) > arch/arm/boot/zImage.ss4000e

And then, use the zImage.ss4000e.
