MTD in a 44B0X borad

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
 @ 0 --  0 % compInternal error: Oops: f9f4e

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

mtd: Giving out device 1 to user partition (256K)
init_mtdchar: allocated major number 90.
init_mtdblock: allocated major number 30.

Any other things I missed here?

Many Thanks,

Which kernel and mtd-utils versions are these?

Hi Josh,

I use kernel 2.4.20 on uClinux 20030522.  And the mtd-utils version is 
default on uClinux 20030522.

Thanks,
Wilson
