[uClinux-dev] re-mount root filesystem

[Harry Gunnarsson]

Earlier, I ran jffs2 root file system, which was per default mounted rw, and
I wanted it ro and 'noatime' set. SInce I couldn't make uClinux set it per
default, I came up with this; re-mounting '/' in the 'rc' script

mount -t jffs2 -o remount,noatime,ro /dev/rom1 /

So in your case, you could try to do

mount -t ext2 -o remount,noatime,rw /dev/<wherever> /

No guarantees though....
