Subject: [DOC2000] invalid size detected
Date: Tue, 10 Dec 2002 15:33:48 +0100 [thread overview]
Message-ID: <001201c2a059$27471aa0$0111010a@nexgenprivate> (raw)
Hi all,
I am trying to access a 8MB DOC2000 using kernel 2.4.20 and MTD lasted CVS
version (using patchin.sh).
The current CVS version detect a bad size for my DOC device when I load
modules using :
/sbin/modprobe -a doc2000 nftl mtdchar
/sbin/modprobe -a docprobe
The previous version I build (2.4.18) detect the correct size but lack for
UnitSizeFactor!=1 support.
I think the problem is in the NAND_IDS.C chip identification but I am not
sure.
As I can see, there is a name conflict beetween nand_ids.h and nand_ids.c.
What de you think of this problems/bug?
Thank.
David.
