hello

we used MPU drivers for MCF5485 processor are configuration LTIB-2008 tool in feedora 12, after power on during rootjffs2 image file copied from flash to ddram at the error cooured error message as shown below following lines

Google "inflate returned -3" gives "About 1,090 results (0.24 seconds)"

Looks like your root filesystem image is corrupt or isn't in the expected format.

Before the error you listed you also got:

Why hide that plain text in a WORD document. That only makes it harder than necessary.

> it shows error inflate returned -3

So what does that mean?

Did google help you find out the cause? Did you look?

Otherwise, you should have the Kernel Source code there. Find the code that calls "inflate" and the "inflate" sources and find what "-3" means to it.

Hint: start in the kernel source tree in "fs/jffs2" and search for "returned". Then you'll find it is including "zlib.h", so ask any friendly Linux system "man zlib". That tells you where it is documented and what "-3" means.

Tracking it down to that level will STILL mean "Looks like your root filesystem image is corrupt or isn't in the expected format."

You may have to rebuild the system from scratch.

Tom

hi Tom

yes i looked, in the kernel source code mentioned in the zlib.h inflate returned -3 means Z_DATA_ERROR, i was rebuild system from scratch in two times but is shows same error (inflate returned -3)

i think during root file system copied image from flash to ddram at the compressing time it caused error, flash and sdram is not syncing, similarly filesystem mount with NFS is worked fine and also got shell prompt in kernel console output.

in NFS i gave link in /tftpboot, No problem only without NFS is not booted, may be i can change filesystem.

Do you only have the one board (that might have a hardware fault) or is this happening on multiple units?

What changed since it last worked?

You can boot over NFS. Once booted, you should try to mount the JFFS2 partition from Linux. You may get "better" error messages from there. At the very least you should try to copy /dev/ntdblock1 back over the network to the machine that you got the rootfs image from, and then compare the original with the one you got back from the device.

Once booted you can copy the rootfs image over the network and use "nandwrite" to write it to the Flash. That may work better.

You may have bad blocks on the Flash and may not be handling them properly. If you use the wrong commands to copy filesystems onto Flash, it can work OK when there are no bad blocks, but fail when there are.

See if you can run "nandtest" on the target to see if there are any problems. If you don't have "nandtest" loaded then you can ask "nanddump" to do much the same thing:

root@triton1:/# nanddump /dev/mtd7 > /dev/null

ECC failed: 0

ECC corrected: 0

Number of bad blocks: 1

Number of bbt blocks: 0

Block size 131072, page size 2048, OOB size 64

Dumping data starting at 0x00000000 and ending at 0x01200000...

"mtd7" has a bad block which is being properly handled.

Does your Flash have any bad blocks in that partition? Maybe you used the wrong command in U-Boot to copy to it. Do you have any other units that don't have bad blocks?

Does your Flash have any spare partitions that you could try copying rootfs to (and then loading that one in the command line) instead?
