OpenWRT on the Ubiquiti RouterStation Pro

By Seb on Friday, January 15 2010, 23:23

I recently replaced my old WRT54GS router with a RouterStation Pro.

Although it already comes with OpenWRT on the board, it is a pretty outdated trunk version.

The documentation for this device is not easy to find and is motly scattered on different wikis and forums. Here is a quick guide on how to flash the latest OpenWRT on this device using tftp.

  • Download the latest snapshot if you don't want to build it yourself: http://downloads.openwrt.org/snapsh... (I use the squashfs version because it is easier to upgrade)
  • Connect your computer to the WAN port
  • Configure your network like this: 192.168.1.1/255.255.255.0 (anything but 192.168.1.20)
  • Plug in your RouterStation Pro
  • Press the reset button and hold it for about 10 seconds (you should see the third led flash a bit and the second on come up)
  • You should be able to ping 192.168.1.20 now
  • Send the firmware image with tftp in binary mode:

Linux:

   $ tftp -m binary 192.168.1.20 -c put openwrt-...-factory.bin

Mac OS X:

   $ tftp 192.168.1.20
   tftp> binary
   tftp> put openwrt-...-factory.bin

The router will reboot and provide dhcp on the switch. You can now telnet to 192.168.1.1 as usual.

Python on OpenWrt Kamikaze 7.09

By Seb on Monday, July 14 2008, 18:32

It is not possible to install python on OpenWrt Kamikaze 7.09 because it depends on libreadline which is not available in the repositories for now.
There is a simple workaround:

  • Install the libreadline from 7.06 (brcm47xx-2.6 for mipsel and atheros-2.6 for mips)
   # ipkg install http://downloads.openwrt.org/kamikaze/7.06/brcm47xx-2.6/packages/libreadline_5.1-1_mipsel.ipk
  • Install python
   # ipkg install python

I tested this on the au1000 7.09 build. It should work on other mipsel and mips builds and on 7.07.

OpenWrt on the MeshCube

By Seb on Sunday, July 13 2008, 19:12

Where I work we use a lot of MeshCubes to create an OLSR powered network.
It is a tiny wireless router with two minipci slots and one Ethernet slot.
It has a 400 MHz MIPS based processor, 64 MB of RAM and 32 MB of Flash.

It is sad that it was discontinued and that the main site (meshcube.org) is down.
There is a mirror here.

The other problem is that the Linux distribution that runs it (nylon) is unmaintained. The good news is that OpenWrt works on the au1500 processor.
The installation without a serial cable is very simple:

  • Download the OpenWrt au1000 images:
   # wget http://downloads.openwrt.org/kamikaze/7.09/au1000-2.6/openwrt-au1000-2.6-vmlinux.bin
   # wget http://downloads.openwrt.org/kamikaze/7.09/au1000-2.6/openwrt-au1000-2.6-jffs2-128k.fs
  • Copy them to the cube:
   # scp openwrt-au1000-2.6-vmlinux.bin root@192.168.0.250:/tmp
   # scp openwrt-au1000-2.6-jffs2-128k.fs root@192.168.0.250:/tmp
  • Make sure nothing writes to the flash (kill most processes but not ssh!)
  • Copy to flash
   # flashcp -v openwrt-au1000-2.6-vmlinux.bin /dev/mtd/2
   # flashcp -v openwrt-au1000-2.6-jffs2-128k.fs /dev/mtd/0

Thats it!
