Result of debugging:

 

The version of the JFFS2 file system in uClinux does not support flash sector sizes that are not 2^n (it is 1056 for the dataflash device I using).

Does anyone know if it supports NAND devices in this version ? Newest version does, but upgrading the MTD/JFFS2 dirs in the kernel tree is not trivial, with respect to getting things to compile.

Hi All,

 

Has anyone been sucessfull in getting the jffs2 file system to run on a MTD block device ?

 

I can erase a MTD block and then mount on it with JFFS2. JFFS2 then checks if the flash is erased all ok and formats the flash.

Then I copy some files to the flash and compares the files. It seems data gets written to the flash.

Then I unmount the flash drive and try to re-mount it again.

It starts the process, bug then hangs indefinitly - looks like a linked list that loops back or something.

It's really horrid to debug this.

 

Any experience ?
