Davinci NAND driver and JFFS2

Nick Gold
Prodigy 40 points

I have a DM355 LeopardBoard and I am trying to set it up to utilize a JFFS2 root filesystem. I am currently using an Arago based kernel 2.6.37. During my kernel boot I see the following messages that pertain to the NAND driver and JFFS2:

JFFS2 version 2.2. (NAND) 2001-2006 Red Hat, Inc.

davinci_nand: probe of davinci_nand.0 failed with error -22

 

Looking at a successful boot from the internet it appears that I should see messages like the following:

JFFS2 version 2.2. (NAND) (SUMMARY)  �© 2001-2006 Red Hat, Inc.
NAND device: Manufacturer ID: 0x2c, Chip ID: 0xda (Micron NAND 256MiB 3,3V 8-bit) <--- The output line that I don't have

4 cmdlinepart partitions found on MTD device davinci_nand.0
Creating 4 MTD partitions on "davinci_nand.0":
0x000000000000-0x0000000a0000 : "UBOOT"
0x0000000a0000-0x0000000c0000 : "UBOOT_ENV"
0x0000000c0000-0x000000480000 : "KERNEL"
0x000000480000-0x0000019e0000 : "FS"
davinci_nand davinci_nand.0: controller rev. 2.3

Once the NAND device is recognized, then the davanci_nand driver seems to understand how to partition the NAND chip.

My question is what device driver to I need to load to have the NAND device recognized?

    Please be sure that JFF2 support is enabled in you linux config file.

    I have the following set:

    CONFIG_MISC_FILESYSTEMS=y
    CONFIG_JFFS2_FS=y
    CONFIG_JFFS2_FS_DEBUG=0
    CONFIG_JFFS2_FS_WRITEBUFFER=y
    # CONFIG_JFFS2_FS_WBUF_VERIFY is not set
    CONFIG_JFFS2_SUMMARY=y
    # CONFIG_JFFS2_FS_XATTR is not set
    # CONFIG_JFFS2_COMPRESSION_OPTIONS is not set
    CONFIG_JFFS2_ZLIB=y
    # CONFIG_JFFS2_LZO is not set
    CONFIG_JFFS2_RTIME=y

    Again, the kernel messages show that the JFFS2 driver seems to load. What I do not see is where the NAND device is recognized. I am unsure what to enable for this to happen.

    Can you explain the steps of how you flashed the JFFS2 filesystem into NAND?

    Try command

    nand erase fs 0xd20000

    before executing

    nand write.jffs2 82000000 fs d20000

    I did the nand erase, and the outcome was the same...still not finding the filesystem.

    1:try nand scrub entirely erase the flash, and after erasing  do nand createbbt which creates bad block table.
    2: then do mtdparts .
    3:Now set a NAND flash offset since later you won't want to write stuffs on the area that contains u-boot  for ex: " dynenv set 40000".
    4: Then you can write the jffs2 in your flash and try booting.
