[Crane, Matthew]

Hi, 

Is the jffs2 image created with an appropriate page size and erase block
for the flash device?

Subject: [uClinux-dev] Problems with the flash memory

Hello everybody.

    I'm having a sort of a problem. I'm using a uClinux distribution
with
the kernel 2.4.xx for the Netburner Coldfire MOD5272 kit. To adress to
the flash memory (an AMD AM29VL160DB) i'm using the blkmem.c file
(with the proper configuration for memory). As far as i have
underthood, the blkmem is used at the start up of the memory. It
defines the memory blocks that we are going to use in size and length.
So far so good.
    To access the filesystem in the flash (/mnt) i'm using the jffs2 to
built the structure of the filesystem. This binary works with the MTD
(binary that writes and reads from the flash) to read and write files
to the /mnt. It keeps a log of all the changes that we operate at the
flash.
    Now the problem.... When i try to read files from the /mnt theres no
problem. It works perfectly. But when i try to write to the flash i
get a strange behavior. When writing small files it works fine (file
around 1-4kB). But when i try to write (copy in this case) a big file
(around 70kB) i get the following error:

# cp file test
cp: unable to open `test': No space left on device

    The problem is that i have plenty of space left in the flash. I
don't
understand what i'm missing here... Can someone give me a clue?
Someone who had a similar problem perhaps...

Thanks for you patience, Jorge Lopes.
