Hi all,
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

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

Any other things I missed here?
Many thanks,
