Content-Type: text/plain; charset=us-ascii; format=flowed Content-Transfer-Encoding: 7bit Does JFFS2 compress data in flash? When I check the available space in Flash df Filesystem 1k-blocks Used Available Use% Mounted on /dev/mtdblock1 32000 5772 26228 18% / But when I erase a file that is 702k big I get: df Filesystem 1k-blocks Used Available Use% Mounted on /dev/mtdblock1 32000 5648 26352 18% / Which means that 124k have been freed. I think there is a compression algorythm involved...? Thanks a lot ]
