AW: AW: doc 2000 unknown partition table

[Fend, Matthias]

ok, i did some further test with the doc2000...

raw write/read on /dev/nftla works fine.

nftldump said this

<snip>
...
sh-2.03# ./nftldump /dev/mtd0 
MTD_open
MTD_ioctl
NFTL Media Header found at offset 0x00100000:
NumEraseUnits:    64
FirstPhysicalEUN: 64
Formatted Size:   983040

but if i use nandwrite i get this messages

<snap>

if i re-read the file with nanddump i get the file but at some locations it
seems to be corrupted. for example :

	That's normal after you've just done nftl_format - there will have been
no 
	partition table on there. If you tried to write a partition table with 
	fdisk and it still said that, then there's something wrong. Check that 
	you can read and write the raw /dev/nftla device. 

	Also, try using the nftldump utility (on /dev/mtd0) to check that the
	contents of the flash are sane.
