Intel IXP1200 and Linux

[Miao Qingjun]

Hi, everybody,

I have problems to run linux from IXA SDK 2.01 onto
an old IXP1200 evaluation board (not IXM1200 board).
I made some config changes, but it does not boot.
The following is my modifications

.config:
   CONFIG_SPECTACLE_ISLAND --> CONFIG_EVAL_BOARD
arch/arm/boot/compressed/Makefile:
   ZTEXTADDR <- 0xc0808000
arch/arm/boot/compressed/head.S:
0xc4004000->0xc0804000 for page table address

drivers/char/serial_ixp1200.c:
38400->9600 for DEFAULT_BAUD

Can anyone figure out which changes I also need to
make?


Thank you

this is your problem.  SDK 2.01 contains the kernel reworked for the
RadiSys board ("bridalveil/SI").  the original EVB with dual gigF 
and 8x 10/100TX doesn't work with this source.

use the source instead from the netwinder.org site with the original
intel IXP1200 how-to information.  (also, getting support on LKML for
the unofficial patches to make IXP1200 work isn't too likely :) 
you'll note that the kernel is pre-2.4.0.  ancient history. these
patches have not been incorporated in the main kernel...)

the SDK 2.x series is commented for the changes made from the 
original how-to release, and massaging #ifdef's in the code _should_
fix it, but seems not to.  i haven't done an exhaustive diff to see
where else changes have been made.

Please have a look at:
