The stable version of OpenWRT (10.03.1) does not work on the LinkSys WRT54G3GV2-VF. The WiFi doesn't work, there are various bugs on trac that say it's fixed in trunk.
However if you browse the download locations, there are two different files for this router with no explanation as to why:
For the unreleased stable version 12.09:
(http://downloads.openwrt.org/attitude_adjustment/12.09-rc1/brcm47xx/generic/)
openwrt-wrt54g3gv2-vf-squashfs.bin
openwrt-wrt54g3gv2-vf-squashfs.noheader.bin
And in the bleeding edge folder:
(http://downloads.openwrt.org/snapshots/trunk/brcm47xx/)
openwrt-wrt54g3gv2-vf-squashfs.bin
openwrt-wrt54g3gv2-vf-squashfs.noheader.bin
I want to upgrade to the latest version to see if the wifi is indeed fixed but can't risk bricking the device.
I suppose noheader could be the old equivalent to sysupgrade. But there is no documentation!
Does anybody know what there are two files and what they are for?
