Re: Accessing DiskonChip

[Sanal Kumar <p_sanalk@yahoo.com>]

Hi David ,

Sorry for not explaining the problem in detail.
I have read the howto's on the infradead .
But still I dont understand how to create a partition
on Disk on chip
and have filesystem on it.
I have tried with nftl_* .But I could not do anything.

Could you please explain what I need to do for making
the filesystem on DOC.

Could not find valid boot record
Could not mount NFTL device

and using nftl_format I tried to format the diskon
chip But I get an error like the following

NFTL_open
ENODEV: thisNFTL = 0, minor = 23808, ip = c94ac4c0, fp
= c965caa0
NFTL_open
ENODEV: thisNFTL = 0, minor = 23809, ip = c94ac6e0, fp
= c965ca20 The only thing I could do was

dd if=XXXX of=/dev/mtd0



I am adding part of my .config here.
