Re: JFFS



 hi 
i am having problem with jffs file sysytem
what did is i removed write32 in cfi_cmdset_0002.c
and replaced it with write8
and i am checking DQ7 and DQ5 to see  erase or write
is completed ,nd i am reading base of each sector
for
status

and now  my flash driver is working perfectly
i am able to erase
write into it

but
now i am creating jffs image
and putting it in flash  using dd
it is doing it
mounting  flash file system 
it is mounting it 
when i power off and mount mtd1 contents of flash
are
retained 

i dont have any problem in creating 

i am able to cp small files to jffs mount point /mnt
and delete it

but problem i faced is when  delete any  file
i get message as 
free memory size accounting screwed up

iam using mkfs.jffs utility

and if i copy a big file some     times it get
hanged
or some times kernel panics
or some times it says no space left on device

down i have put

this message i get  when i try to delete file

here rm1 is nothing but rm

and after a series of command it panics
verbosity i have given is 0

and if i give verbosity 3

a message continously displays as  wake up thread
time.....
