hi
I'am having trouble eraseing the doc2000.
I use doc2000(NAND device: Manufacturer ID: 0x98, Chip ID: 0x75 (Toshiba
NAND 32MiB 3,3V 8-bit)).This is a linux with kernel 2.4.27 and the
mtdsnapshot 20041128.
The dmesg show:
Dec 16 08:46:16 localhost kernel: mtd: Giving out device 0 to DiskOnChip
2000 (NFTL Model)
Dec 16 08:46:16 localhost kernel: Creating 1 MTD partitions on
"DiskOnChip 2000(NFTL Model)":
Dec 16 08:46:16 localhost kernel: 0x00014000-0x02000000 : " DiskOnChip
BDTL partition"
and the /proc/mtd show:
[root at localhost util]# cat /proc/mtd
dev: size erasesize name
mtd0: 02000000 00004000 "DiskOnChip 2000 (NFTL Model)"
mtd1: 01fec000 00004000 " DiskOnChip BDTL partition"
It seems to be ok.
Then I use utils/erase
[root at localhost util]# ./flash_eraseall -j /dev/mtd1
./flash_eraseall: /dev/mtd1: No such device
but I am sure the mtd* device exist.
I have use MAKEDEV.
[root at localhost util]# ls -l /dev/mtd*
