Introduction

journaled flash file system (jffs) is used to store user programs and data into otherwise inacessible flash memory. Inspite of general purpose read/write one must take care not to store frequently changed files on it as this can cause flash wear out. Journal file is used to minimize frequent overwrites.

Instructions

To enable jffs (please read note about "flash wear out" above!) enter the following commands (when you're connected via ssh or telnet on a shell):

nvram set sys_enable_jffs2=1
nvram commit
reboot

Maybe the options in the webinterface below work for you (they didn't for me):

Administration:
JFFS2 enabled: X Enable Disable
Clean JFFS2: X Enable Disable


Testing

Log in and run:
ipkg update
ipkg list
