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...
