you should try reading the entire fs out of the spi flash and comparing it to the original in memory to make sure they match. or doing a crc on it.
if you start at the *first* error instead of the last (which is almost always the important one), it indicates there is an issue:
jffs2_scan_eraseblock(): Node at 0x0000000c {0x1985, 0xe000, 0x00000000) has invalid CRC 0x04000284 (calculated 0xc149957c)
you're also using 2009R1.1 ... you should upgrade your stamp board (u-boot and kernel) to 2010R1

the partition info you've shown between these two boots are not the same. verify the partition map displayed while booting matches what you're actually using in u-boot.

In the stamp.c , I have configured the partition as below
#if defined(CONFIG_MTD_M25P80) \
|| defined(CONFIG_MTD_M25P80_MODULE)
static struct mtd_partition bfin_spi_flash_partitions[] = {
{
.name = "bootloader(spi)",
.size = 0x00040000,
.offset = 0,
.mask_flags = MTD_CAP_ROM
}, {
.name = "linux kernel(spi)",
.size = 0x180000,
.offset = MTDPART_OFS_APPEND,
}, {
.name = "file system(spi)",
.size = MTDPART_SIZ_FULL,
.offset = MTDPART_OFS_APPEND,
}
};
In the earlier post I had configured the kernel size area for 1.1875MB
Later as seen from the above config, I reserved 1.5MB for the kernel
With this config, accessing the flash area for storage with booting being done using uImage works fine.
The size of vmImage comes around 900kB
@Robert: I have already gone through that line

Could you follow Mike's advice, first flash your jffs2 image into SPI flash according to our wiki page: docs.blackfin.uclinux.org/doku.php?id=linux-kernel:jffs&s[]=jffs2. Then boot your board from RAM, by tftp load the uImage instead of from your SPI Flash, then use dd or cat to raw read your SPI flash jffs2 partition into ram, and compare it with the jffs2 image you flashed into the Flash?

you clearly are still not using the right command. if you did, there would be no garbage output like you keep showing.
if you cant figure out `dd`, then use `cat` and redirect it into a file which you can then offload and compare elsewhere.

have you addressed the actual error it is showing you ?
"Perhaps the file system was created with the wrong erase size?"
if your erase block size is 4KiB, why are you creating an image with an erase block size of 64KiB ?

Hi Krish,
I am trying to duplicate your problem on my board. I have an ADI BF518 ezboard on hand and the SPI Nor flash on it is of 2MB, so it's not able to hold the default uboot and jffs2 file system together on it however I managed to flash a random jffs2 filesystem on it and do the mount, read, write for test, it turn out to be fine. Following is what I did and this should also make sense for you. You may take it as reference and have a try on your board to see if it works and give us the feedback before finding the solution for your problem:
1) Trim the romfs under the Linux-dist, remove some thing so it's thinner enough to be hold on my 2MB flash
2) Then using the default way our distribution use to make the jff2 image: 2010R1/user/mtd-utils/mkfs.jffs2 -l -p -2010R1/romfs -D device_table-min.txt -o 2010R1/images/rootfs.jffs2
3)use the u-boot, tftpboot and sf utils to flash the rootfs.jffs2 to the SPI Flash
a)tftpboot 0x1000000 rootfs.jffs2
b)sf probe X
c)sf erase 0x40000 0x1c0000 (note that in the bf518 ezbrd.c by default there is only two MTD partition on SPI flash, I am using the second one starting for physical addr 0x40000 for this test)
d)sf write 0x1000000 0x40000 0x20000 (0x20000 is the rootfs.jffs2 image size after trimming down)
e)read the spi out and confirmed that the 0x19 0x85 is there at the head as expected
4)reboot to Linux, mount -t jffs2 /dev/mtdblock1 /mnt
5)next read/write test works fine.
Maybe you can try this on your board first.

By step two I was showing an example of how we did in the distribution to build jffs2 image, it's simply a command like "2010R1/user/mtd-utils/mkfs.jffs2 -l -p -2010R1/romfs -D device_table-min.txt -o 2010R1/images/rootfs.jffs2", using the mkfs.jffs2 with proper options. Actually if you check the output log for the distribution make you will see it.

No idea for your case since everything works fine on my side, just some general advice for your reference. Does the MTD partition offset match 0x340000 in your code? Does the SPI Nor flash pass the read/write test in all it's address space in uboot? Is the jffs2 image read out from SPI Nor matches the one write to it well? have you dig more following the error reported by jffs2 in the log? If none of these work it's time for you to debug. www.linux-mtd.infradead.org/faq/jffs2.html may help.
