No space left on device

["Sebastian" <sebastian.vaitus@masstechgroup.com>]

Hi,

I'm trying to use JFFS2 on a 512K AMD (AM29F040B) flash chip (8 erase
blocks) installed on the IBM Walnut board. I was able to create a JFFS2
image with mkfs.jffs2, erase the flash, and then copy the image to the flash
( about 200 bytes). I can mount the mtdblock and browse the files on the
JFFS2 file system, but I cannot make any changes to the existing files or
add new ones. Everytime I try to modify it I get the 'No space left on
device' error. I had a quick look through the JFFS2 code and I see that
there has to be at least 5 free erase blocks (+ data) for the FS to function
properly ... but I have 8! I tried changing JFFS2_RESERVED_BLOCKS_BASE from
3 to 1 (which gives a total of 3 blocks for minimum requirement) and it
still didn't work. Am I missing something here? Do I have to pad my image
with 0xFF and make it 512K before I copy it? Is there another way to make
the image and copy it to the flash ... etc?
