MTD in a 44B0X borad

[Wilson]

Hi all,
Please give me a hand.. I need to get it done ASAP... Thanks.

I would like to enable MTD in S3C44B0X with NOR flash SST 39VF160.

When I erase mtd1, I got the following error messages:
/> eraseall /dev/mtd1
MTD_open
MTD_ioctl
Erasing 4 KibyteMTD_ioctl

1) Do I need to modify the lock address 5555/2AAA in jedec_probe.c?
2) Do I need to modify the interrupt table(seems like an interrupt error)?

P.S The boot up message of uClinux: (It looks good to me)
s3c4510b flash device: 200000 at 1000000

Any other things I missed here?

Many Thanks,
