FFS bad content in subdirectory

Hi all,

 

I'm using TWR-VF65GS10 with MQX and added FFS subsystem in order to work with a 'hard disk' on my NAND flash.

Everything seems to work fine but some times when I check a subdirectory content, it appear a lot of trash, like this:

 

shell>

shell> cd c:\

shell> dir

COCO.TXT           41 01-01-1980 00:00:00      A COCO.TXT

DIR1                0 01-01-1980 00:00:54     D  DIR1

FOO.BAR          1000 01-01-1980 00:01:24      A FOO.BAR

shell> cd dir1

shell>

shell> pwd

c:\dir1

shell>

shell> dir

pqrstuvw.xyz      1145258561      01-29-2011 07:33:54     DA pqrstuvw.xyz

EFGHIJKL.MNO 1684234849      02-29-2027 11:34:54     D  EFGHIJKL.MNO

efghijkl.mno        959985462      09-18-2005 06:09:32     DA efghijkl.mno

yz012345.678     1296845642      10-06-2015 08:42:08 R  VDA yz012345.678

NOPQRSTU.VWX      1835821930 11-06-2031 12:43:08 R  VD  NOPQRSTU.VWX

 

 

Note that the trash has some meaning, I mean, when we use the command 'Write' to fullfill a file, it wirtes sequential ASCII into the file, like this:

 

shell>

shell> read foo.bar

Reading from foo.bar:

0123456789:;<=>?@ABCDEFGHIJKLM

Done.

shell>

 

It seems to me the FFS is scrambling its FAT or something like this, it's messing up the file content with the dir content.

 

Please, any help?
