Hello,

Hi,


I have a Marvell 88F6281 Reference design board I'm trying to compile a
2.6.28 kernel for. Although, the machine id check is failing. The error is
as follows

Uncompressing
Linux.............................................................................................................................
. done, booting the kernel.

Error: unrecognized/unsupported machine ID (r1 = 0x0000020f).

Available machine support:

ID (hex) NAME
00000690 Marvell DB-88F6281-BP Development Board
00000691 Marvell RD-88F6192-NAS Development Board
00000692 Marvell RD-88F6281 Reference Board

Please check your kernel config and/or bootloader.

This is because the boot loader passes in the wrong machine ID.

If you have the u-boot "arcNumber" parameter, try setting that to
the correct machine ID before booting the kernel. Otherwise, you
can prepend a bit of code to the zImage that sets the machine ID to
the right value, e.g. for the 6281 RD:

(echo -en "\x06\x1c\xa0\xe3\x92\x10\x81\xe3"; cat zImage) > zImage.rd88f6281

and then use mkimage on zImage.rd88f6281 to create a uImage that you
can boot on the board.
