DiskOnChip - mount partition

DiskOnChip - mount partition

[Ruediger Haertel]

Hello

I have a DoC Mil+ 16MB. I am using 2.4.27-uc1 with this MTD 
configuration:

CONFIG_MTD
CONFIG_MTD_PARTITIONS
CONFIG_MTD_CHAR
CONFIG_INFTL

CONFIG_MTD_DOC2001PLUS

The chip is correctly detected, after I removed the "2 way 
interleave" in doc2001plus.c.
Then I did a 
   nftl_format -b -i /dev/mtd5 98304
and
   docfdisk /dev/mtd5 50 0
which should give me /dev/mtd6 and /dev/mtd7 as far as I know.
However accessing /dev/mtd6 with
   eraseall /dev/mtd6
says: eraseall: /dev/mtd6: No such device

Device /dev/mtd6 has the following device files:
crw-------    1 0        0         90,  12 /dev/mtd6
brw-------    1 0        0         31,   6 /dev/mtdblock6
crw-------    1 0        0         90,  13 /dev/mtdr6

 inftla: unknown partition table

## snap

Do you have any hint what is going wrong or any pointer where I 
should look.

Hello,

First of all I would suggest to use newer diskonchip driver under the 
nand sub-menu (CONFIG_MTD_NAND_DISKONCHIP) and a recent kernel (2.6.13 
for example).
Also take a look at 
http://www.linux-mtd.infradead.org/source.html#kernelversions .
