Subject: Patching only NAND specific stuff possible?
Date: Wed, 11 May 2005 10:25:58 +0200 [thread overview]
Message-ID: <4281C196.2010806@rac.de> (raw)
So again me with my SAMSUNG NAND.
Is it a possibility to patch only the NAND related stuff
driver/mtd/nand/*
include/linux/mtd/nand*
??*
to support new NAND features...
Considering the four Layers (jffs2,mtd,nand,hardware-drivers) it should
be possible onloy to 'update' the nand and hardware-drivers stuff.
Any objections to this?
A secondary short question, if you don't mind.
Where takes the 'addressing' of the NAND takes place (write Col,Row to ALE)?
On the Samsung K9F2G08... there are 5 Cycles for the address resolution
nescessary. And two for the command. Example Read page..
Command=0x00
Address=Col_addr(BIT 0-7)
Address=Col_addr(BIT 8-11)
Address=Row_addr(BIT 0-7)
Address=Row_addr(BIT 8-15)
Address=Row_addr(BIT 16)
CLE=0x30
Then read Data...
I saw some NAND chips which only have 4 Address Cycles.
Kind Regards Marcus
