Typically uClinux systems mount the root filesystem as readonly, with 
ROMFS or CRAMFS, and mount a ramdisk on /var.

check to see if you can create files and directores in the /var 
directory on your board.

OFcourse, you lose the contents of any changes when you power off the 
board.  If you need it to be persistent, look into JFFS2 and flash. 
There have been amy messages about this on the list in recent months.
