In my last email :

  but something is strange since df indicates that there is no space
left
  on that fs ; but the file I have written on my 2Meg partition was only
  1.5Meg
  /mnt/jffs2/jffs2_1/usr/arm/arm-linux # df
  Filesystem           1k-blocks      Used Available Use% Mounted on
  /dev/ram0                 3963      2997       966  76% /
  /dev/mtdblock1            2048      2048         0 100%
  /mnt/jffs2/jffs2_1
  /dev/ram1                 2011        13      1998   1%
/mnt/ramdisk/rd1

So if you say that it needs at least 5 free blocks, it means that I need
5 blocks of 128KB, so at least 650KB free!!!
Is it necessary ?

In fact if this is true, a 2MB partition is to short...
