Hi all,
I’m debugging JFFS2 file system on NAND FLASH NAND08GW3B2C (8-bit width) with Freescale QorQ P4080 silicon 2.0.
u-boot is 2010-06. The kernel is 2.6.34.6. Both are using 36-bit addressing. Using "nand erase clean" to format NAND FLASH:
<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<-----------------------------------------
=> nand erase clean
NAND erase: device 0 whole chip
Bad block table found at page 524224, version 0x01
Bad block table found at page 524160, version 0x01
nand_read_bbt: Bad block at 0x000002be0000
Skipping bad block at 0x02be0000
Skipping bad block at 0x3ff80000
Skipping bad block at 0x3ffa0000
Skipping bad block at 0x3ffc0000
Skipping bad block at 0x3ffe0000
OK
----------------------------------------->>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
Then boot the board with NFS boot. Boot log for MTD (the first 0x1000000 bytes are reserved):
<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<-----------------------------------------

The NAND JFFS2 partition can be mounted successfully and I can read/write files on it. Then I re-mount it but error " jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found " happens and then I dumped the page at 0x3ed40000:

Thanks for the answer.
I've already checked this point. The blocksize in the JFFS2 creation
(-e option) is ok.
And in my platform is working properly, even when exercizing the
filesystem with a tool like iozone.
The only case that fails is when powercycling on/off the unit frequently.

Is it possible that your erase_block size is wrong (too small). I
had the opposite experience with SST parts erasing 32k when I
expected 4k.

Hi again,
Do you know another forum where I can post on ?
(linux-mtd on infradead, was the only I found relevant for this kind
of question)
I'm really having hard time with this issue, and some new ideas or
experiences might be really helpfull.
thanks,
Jean-Laurent

Hi,
I'm running linux 2.6.9 on an ARM based platform booting from Uboot.
My root filesystem is a flash partition.
And I'm experiencing flash JFFS2/MTD corruption on some units while
power cycling its on/off after 1 day of usage.
I saw several posting on the subject, but none about a fix or
workaround. Most of its were talking about powering off units while
accessing the FS (write or erase block)
I'm trying to investigate more deaper the problem, by setting up
something like a watchdog and adding FS stress test.
So if you've experienced similar issue and you've finally fixed it or
workarounded it, please let me know.
thanks,
Jean-Laurent
Here are the details of my configuration :
Here is my flash topology :
Probing Flash2 at physical address 0x04000000 (16-bit bankwidth)
Flash2: Found 1 x16 devices at 0x0 in 16-bit bank
Intel/Sharp Extended Query Table at 0x0031
cfi_cmdset_0001: Erase suspend on write enabled
Using buffer write method
RedBoot partition parsing not available
cmdlinepart partition parsing not available
Using static partitions on Flash1
Creating 5 MTD partitions on "Flash1":
0x00000000-0x00020000 : "BootLoader"
0x00020000-0x00040000 : "BIOS Data"
0x00040000-0x001c0000 : "Fixed Kernel"
0x001c0000-0x00340000 : "D/L Kernel"
0x00340000-0x02000000 : "Root File-system"
My flash device is intel stratflash 128J3C type.
Everything works properly on the major part of my units.
About ~ 5% of our devices are experiencing data corruption in Flash
when Power Cycling the unit.
What I mean by data corruption is :
- bad CRC of the kernel image in flash.
- corruption of the JFFS2 filesystem with the following errors .
I have set the JFFS2 debug level to 2 to have more infos :
