connecting IDE directly to MPC8xx

Hello guys,

I am using PPCBoot on my board with MPC823E.
I am lucky and I ported Linux on this board. All
works well but I don't know, how to configure
kernel 2_4_3 form ElinOS v2.0 to work with IDE hard disk connected directly to MPC823 bus (utilizing PCMCIA bus signals
in way PPCBoot does it - in PPCBoot my IDE disk works well).

In kernel 2_4_3 from ElinOS v2.0 I use this options:
CONFIG_BLK_DEV_MPC8xx_IDE=y
CONFIG_IDE=y
CONFIG_BLK_DEV_IDE=y
CONFIG_BLK_DEV_IDEDISK=y
CONFIG_IDEDISK_MULTIMODE=y
CONFIG_PARTITION_ADVANCED=y
CONFIG_MSDOS_PARTITION=y
CONFIG_BLK_DEV_IDE_MODES=y
But It doesn't work at all. It crashes in do_probe() function, when accessing bad memory region. I have mapped all
PCMCIA regions correctly.
Is any straightforward way to configure kernel to work with this IDE connection ?
Thanks in advance, HANYS

Dear Jan,

Congrats!

These options look OK to me; for another example please see
http://www.denx.de/doc/TQM8xxL/advanced-topics.html#FLASH-DISKS

Probably the ElinOS kernel does not support this properly.

Feel free to try the kernel from our CVS server which has been used
with such configurations in several projects. See

Best regards,

Wolfgang Denk
