I have build my own compilation and try to use maximum space available. It works fine with old versions. Image size is
-rw-r--r-- 1 apache apache 3932160 окт 31 2012 openwrt-ar71xx-generic-tl-wr740n-v4-squashfs-factory.bin
-rw-r--r-- 1 apache apache 3670020 окт 31 2012 openwrt-ar71xx-generic-tl-wr740n-v4-squashfs-sysupgrade.bin
this leaves around 100k free space. Here is mount points on old working build:
root@OpenWrt:~# df -h
Filesystem Size Used Available Use% Mounted on
rootfs 320.0K 240.0K 80.0K 75% /
/dev/root 2.8M 2.8M 0 100% /rom
tmpfs 14.4M 88.0K 14.3M 1% /tmp
tmpfs 512.0K 0 512.0K 0% /dev
/dev/mtdblock3 320.0K 240.0K 80.0K 75% /overlay
overlayfs:/overlay 320.0K 240.0K 80.0K 75% /
Everythink is normal and works without problem. Here is the new build (today downloading of sources AA build 40498)
root@OpenWrt:~# df -h
Filesystem Size Used Available Use% Mounted on
rootfs 320.0K 224.0K 96.0K 70% /
/dev/root 2.8M 2.8M 0 100% /rom
tmpfs 14.3M 340.0K 14.0M 2% /tmp
tmpfs 512.0K 0 512.0K 0% /dev
/dev/mtdblock3 320.0K 224.0K 96.0K 70% /tmp/overlay
root 14.3M 36.0K 14.3M 0% /tmp/root
overlayfs:/tmp/root 14.3M 36.0K 14.3M 0% /tmp/root
/dev/mtdblock3 320.0K 224.0K 96.0K 70% /overlay
overlayfs:/overlay 320.0K 224.0K 96.0K 70% /
I can create/save files in / folder, change password (must not happend). but wireless configuration is lost after reboot. I guess it is writen in /tmp/root folder.
Any advice how to fix that? Except rebuild and make more free space.
