MTD CVS: missing JFFS2?

MTD CVS: missing JFFS2?

[Jeffrey Lim]

Hi guys, i follow the instructions found at
sources.redhat.com/jffs2 and download the latest MTD source from CVS.

under the patches subdir, there is a patchin.sh, which i run.

However, after taking a look at patchin.sh, i realize that the jffs2 code
doesnt seem to get patched at all!, only jffs. Am i therefore to assume
that the MTD CVS does not contain any jffs2 code at all, and that i
should just use the jffs2 code from the stock kernel?

Any help/explanation would be appreciated. Thanks.

(according to sources.redhat.com/jffs2 -
"JFFS2 has been included in the official Linux kernel since the 2.4.10
release. The latest code is available from the Memory Technology Device
(MTD) CVS tree at cvs.infradead.org. To obtain an up to date copy, use
the following commands:...")

NAND flash of EDB7312

[Taeil Um]

i recently tried to use NAND flash of EDB7312 while using kernel 2.4.18
But, i didn't succeed.
My EDB7312 board just can read DEVICE ID of NAND flash like below,

----Manufacture ID: 0x98, Chip ID: 0xe6 (Toshiba TC58V64AFT/DC)

But, i can't access /dev/mtd?, even though i configured MTD stuff.
i think some timing factor would be problems.


So,  Did anybody succeed to use NAND flash on EDB7312 board ?
if somebody succeed, Could you inform me the value of MEMCFG1? 

Any Other comment will be welcome.

Bye!

It worked ok for me using ARMboot (armboot.sf.net) and Elinos, which
uses the driver checked in on Infradead. As for MEMCFG1, see
armboot/board/ep7312/memsetup.S:

...
memcfg1_val:    .long   0x1f101710
...

CVS definitely contains jffs2 code, but I never used patchin.sh. By
hand, you would switch fs/jffs2 and include/linux/jffs2*.

Hope that helps.

I see - thanks a lot!

I suppose patchin.sh might still be useful? Even if it doesnt patch in
the latest jffs2 code, it certainly does the cvs mtd code..

Actually, if it doesn't patch jffs2 as well, that should be fixed. But
I might not be the best person for this, as I have never used it so
far.

I assume David Woodhouse is the person to whom i should submit the patch
to patchin.sh to? (oh boy).

I'll have a patch ready first thing i get to work later.

Correct. It would be nice, if you cc'd the mailinglist as well.
