canT use jffs2 with nand

canT use jffs2 with nand

[Stephan Linke]

Hi,

I'm trying to use some nand chips on my board. Some selfmade tests in the bootloader show that they are already working fin in the
system.
But I have trouble using them in linux.
When trying to use touch to create an empty file on a JFFS2 mounted on the nand I get the following result: "nand_write_ecc: Attempt
to write not page aligned data" which is actualy true since the FS is trying to write only 12 bytes...
I tried to use YAFFS first but the result was more difficult to "translate".
Writing an mounting a cramfs image worked fine.

Any help is appreciated.
  Thanks, Stephan

P.S.: I have pretty new MTD and YAFFS sources and a 2.4.18 kernel.

Seem's, that CONFIG_JFFS2_NAND is missing.
Have you used patchin.sh ?
Have you read http://linux-mtx.infradead.org/tech/nand.html ?

Hi Thomas,

actualy I did not use the patch script. But on the other hand I don't like the way it modifies my kernel. Since CVS can't deal with
links...
Is it possible to add an option that uses copies instead of links?
That would be fine.

Now I will test it with the automaticaly patched kernel. Thanks.

CVS up. 
./patchin.sh -c ....
will copy the files into the kerneltree instead of linking them.

Hi,

Still the same result. JFFS2 uses wrong size when accessing NAND flash:
...
Write clean marker to block at 0x00018000 failed: -22
nand_write_ecc: Attempt to write not page aligned data
Write clean marker to block at 0x00014000 failed: -22
nand_write_ecc: Attempt to write not page aligned data
Write clean marker to block at 0x00010000 failed: -22
nand_write_ecc: Attempt to write not page aligned data
...

And I could not find any CONFIG_JFFS2_NAND mentioned in my sources. Maybe some misspelling?


Thanks, Stephan

P.S: Once again I had to patch nand.h after using the patchin.sh script since nand_ids.c doesn't include mtd.h before includeing
nand.h...
