The RouterStation Pro comes preloaded with a relatively old installation of OpenWRT Kamikaze. Being a sucker for bleeding-edge software, I definitely wanted to check out code from the main Subversion repository to get it up-to-date as far as development goes. Here’s how I did it.
bkero@ponderosa ~ $ svn co svn://svn.openwrt.org/openwrt/branches/backfire bkero@ponderosa ~ $ cd backfire bkero@ponderosa ~/backfire $ make menuconfig
Now you select some options to specify that we are building an OpenWRT image for a RouterStation Pro:
Target System (Ateros AR71xx/AR7240/AR913x) Target Profile (Ubiquiti RouterStation Pro)
Select the Exit option by pressing the right arrow key, then hit Enter. Save the config, then:
bkero@ponderosa ~/backfire $ make -j4
Adjust -j4 for the number of cores in your box(n+1 or n*2) are popular. This is going to take quite a while, so go to lunch or watch some more Star Trek.
If all goes well, you should have several image files ready.
bkero@ponderosa ~/backfire $ ls bin/ar71xx/ md5sums openwrt-ar71xx-rootfs.tar.gz openwrt-ar71xx-root.jffs2-128k openwrt-ar71xx-root.jffs2-64k openwrt-ar71xx-root.squashfs openwrt-ar71xx-root.squashfs-4k openwrt-ar71xx-ubnt-rspro-jffs2-factory.bin openwrt-ar71xx-ubnt-rspro-jffs2-sysupgrade.bin openwrt-ar71xx-ubnt-rspro-squashfs-factory.bin openwrt-ar71xx-ubnt-rspro-squashfs-sysupgrade.bin openwrt-ar71xx-uImage-gzip.bin openwrt-ar71xx-uImage-lzma.bin openwrt-ar71xx-vmlinux.bin openwrt-ar71xx-vmlinux.elf openwrt-ar71xx-vmlinux.gz openwrt-ar71xx-vmlinux.lzma packages
We’re concerned with the file “openwrt-ar71xx-ubnt-rspro-squashfs-factory.bin”. Make sure the box you’re doing this on has the ‘tftp’ package installed. A second ethernet interface would also be helpful.
Unplug your RouterStation Pro. Hold the reset button down and plug the power back in. Hold the reset button down until the RF LED on the front of the board becomes solid. Plug a computer into the WAN port of your RouterStation Pro. For some reason it brings up 192.168.1.20 on the WAN port, and the LAN ports become unused.
bkero@ponderosa ~/openwrt/backfire.rspro/bin/ar71xx $ tftp 192.168.1.20 tftp> binary tftp> put openwrt-ar71xx-ubnt-rspro-squashfs-factory.bin Sent 2949120 bytes OK. tftp> quit
Give your router 10 minutes for the recovery process to run. Plug your computer back into a LAN port and try pinging 192.168.1.20(the default IP). Mine didn’t come back up alright with the default configuration settings, so I had to hold the reset button down for 20 seconds(LEDs on the board will change). Afterwards, the router was up and pingable/telnetable at 192.168.1.20. Telnet in and you’ll be presented with a default installation of OpenWRT.
Right now the system will be probably useless for you. To install a familiar web interface for configuration, simply install luci:
root@rspro:~$ opkg install luci root@rspro:~$ passwd Enter new UNIX password: Retype new UNIX password: passwd: password updated successfully root@rspro:~$ /etc/init.d/uhttpd enable root@rspro:~$ /etc/init.d/uhttpd start Starting uhttpd... OK
Now point your browser at http://192.168.1.20, and login!
