[U-Boot] JFFS2 duplicate file entries

[Fei, Yiyang]

Hi,

 

I'm using the 2010.12 u-boot source code.  I use a JFFS2 partition on a
NAND flash to store the kernel image as well as an FGPA images for my
platform.  I also mount this partition inside the kernel because I need
the ability to overwrite the contents during a field-upgrade of the
embedded software.  When I make changes to this partition from the
kernel, everything looks correct.  But when I reboot and break into
u-boot, the contents of the partition is incorrect.  For example, if I
do the following from the kernel...

 

/mnt/bootfs # ll

-rw-r--r--    1 64105    62004      9232568 Feb 10  2011
netviz_core_fpga.bit

-rw-r--r--    1 64105    62004      2138968 Feb 10  2011 uImage

/mnt/bootfs # touch test

/mnt/bootfs # ll

-rw-r--r--    1 64105    62004      9232568 Feb 10  2011
netviz_core_fpga.bit

-rw-r--r--    1 root     root             0 Jan  1 00:27 test

-rw-r--r--    1 64105    62004      2138968 Feb 10  2011 uImage

/mnt/bootfs # rm test

/mnt/bootfs # ll

-rw-r--r--    1 64105    62004      9232568 Feb 10  2011
netviz_core_fpga.bit

-rw-r--r--    1 64105    62004      2138968 Feb 10  2011 uImage

/mnt/bootfs # echo "some text" > test

/mnt/bootfs # ll

-rw-r--r--    1 64105    62004      9232568 Feb 10  2011
netviz_core_fpga.bit

-rw-r--r--    1 root     root            10 Jan  1 00:27 test

-rw-r--r--    1 64105    62004      2138968 Feb 10  2011 uImage

/mnt/bootfs # reboot

 

During the boot, if I break into u-boot, here is what I see...

 

Hit any key to stop autoboot:  0

 -rw-r--r--        0 Thu Jan 01 00:27:14 1970 test

 -rw-r--r--       10 Thu Jan 01 00:27:42 1970 test

Do you have any suggestions on how I should track down the cause for
this problem?
