Flash appears to be ROM, readonly.

[Derek Ross]

Hello,
I'm running the mtd_debug.c app, and when I use the
"info" switch, I get the following:

 mtd.type = MTD_ROM
 mtd.flags = MTD_CAP_ROM
 mtd.size = 8388608 (8M)
 mtd.erasesize = 65536 (64K)
 mtd.oobblock = 0
 mtd.oobsize = 0
 mtd.ecctype = MTD_ECC_NONE
 regions = 0

If I try to write or erase a sector, the app immediately
exits as soon as it tries to open the file discriptor 
with O_RDWR flag set.

If I run a "cat /proc/mtd" I get:

 dev:  size     erasesize   name
 mtd0: 00800000 00010000    "flash"
 mtd1: 0000c000 00000010    "SRAM"
 mtd2: 00000080 00010000    "BootROM"


The hardware details are:

CDB89712 (rev B) development board.

Flash TE28F320 B Jedec, not CFI
Will later be using C for final product, which is CFI

Kernel is 2.4.6-rmk1-rayl1, and we also have 2.4.16-rmk2
We can upgrade mtd drivers if necessary.

Thank you,
Derek Ross.
