FFS bad content in subdirectory

sandrobastos — Tue, 25 Mar 2014 12:47:38 GMT

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?
