Unable to mount with jffs2

[Samir]

Hello

I am using the same AT91rm9200,SST39vf3201 with 2.4.27-vrs1 Kernel.

I am able to mount the jffs2 on mtdblock0.
I am not using the jffs2 image.
I am getting message like below.
But able to mount flash with same error

# cat /proc/mtd
dev:    size   erasesize  name
mtd0: 00400000 00001000 "Physically mapped flash"
# mount -t jffs2 /dev/mtdblock0 /mnt

ok

Subject: Unable to mount with jffs2

Hi community,

I am using a 2.6.17 kernel with patches from 
http://maxim.org.za/at91_26.html on a AT91RM9200 board. I am facing problems

with mounting jffs2 on my flash. The reported errors are related to the 
magic number 0x1985. I understand that the archive and linux-mtd FAQ has 
similar problems with this magic number thing, but I'm afraid I'm still not 
moving forward after a few days (I will try to search again though). Thus, 
appreciate your kind patience.

My MTD profile with the "cat /proc/mtd" command is:

    dev:    size   erasesize  name
    mtd0: 00400000 00010000 "flash1"
    mtd1: 00080000 00010000 "Bootloader"
    mtd2: 00080000 00010000 "zImage"
    mtd3: 00080000 00010000 "Ramdisk.gz"
    mtd4: 00280000 00010000 "User FS1"
    mtd5: 00400000 00010000 "flash2"
    mtd6: 00400000 00010000 "User FS2"

I was not able to mount mtdblock6, which is the 2nd piece of flash. Both 
flash parts are SST39VF3201. The following is what have I done.

1. At my host system, I created a JFFS2 image with the mkfs.jffs2 tool (ver 
1.50). The command I use is:

    mkfs.jffs2 -d jffs2 -e 0x10000 -o jffs2_64K_block.img

2. At my target, with U-boot, I erase the 2nd piece of flash entirely.

3. When my board boots up, I copied the JFFS2 image to mtdblock6. The 
command I use is:

    cp jffs2_64K_block.img /dev/mtdblock6.

The copying works fine.

4. Next, I try to mount with:

    mount -t jffs2 -o noatime /dev/mtdblock6 /mnt

What follows is a long list of error messages as follows:

5. After the last line, the system just stays there without returning to the

prompt until I intentionally hit the return key.

6. Some other background info: I created the flash part entry in 
jedec_probe.c with the erase region of:

    ERASEINFO(0x10000, 64),

This is also the reason why I think the JFFS2 image (created with the 
mkfs.jffs2 tool) should be specfiied with the "-e 0x10000" erase block size.

7. At the same time, I have modified the do_erase_oneblock( ...) function in

cfi_cmdset_0002.c by changing:

   map_write(map, CMD(0x30), adr);

to
   map_write(map, CMD(0x50), adr);

I thought that this should be appropriate since 0x50 is used for block erase

size of 64K, while 0x30 is used to indicate sector erase size of 4K. (Am I 
doing the correct steps?)

8. Part of the boot log is as shown:

Found: SST 39VF3201

cfi_cmdset_0002: Disabling erase-suspend-program due to code brokenness.

Are there any steps I have missed out? Thanks in advance.

Tze Wan
