JFFS2 directory copy problem
|
From: Cmmn Ml <cm...@ya...> - 2007-04-23 12:01:02

Hi all,
We are working on a SH 7705 processor based board.
The linux kernel we are using is 2.6.16 with SH linux stable patch (sh--stable--2.6.16). At the moment the linux kernel
is running well with basic features. We're getting following problem with flash file system (JFFS2).
We have two flash partitions on our system and can be mounted using JFFS2.
Once partitions are mounted we can do standard file system operations like create/remove directories, files.
But when we try to copy a directory, it copies the files inside the directory and at the end the system crashes
with following errors. Further more copying individual file, one by one doesn't make any problem.

---------------------------------------------------------------------
We're using Solution Engine as the target board and modified the linux-2.6.16.9/drivers/mtd/maps/solutionengine.c file
according to our needs. Flash memory type is Spansion (MirrorBit family) S29GLxxxN.
If any one knows why this happnes and give us some thoughts on this, it will be a great help.
Thank you in advance
