This is spookey, I just got the exact same problem at the same time(!)
I'm trying to write data to my Dataflash device, but I get a "permission
denied" error whenever I try to fopen the file "/dev/mtd/2" to write the data
into it. I can read data from it with no problems.
I have tried "mtd_debug write" and "flashcp" and they return permission denied
as well. Am I missing something?
I am using 2.4.27-vrs1 with cvs mtd patched.
/root # mtd_debug info /dev/mtd/2
mtd.type = MTD_NORFLASH
mtd.flags = MTD_ERASEABLE
mtd.size = 786432 (768K)
mtd.erasesize = 1056 (1K)
mtd.oobblock = 0
mtd.oobsize = 0
mtd.ecctype = MTD_ECC_NONE
regions = 0
