I've got an EAP650 Outdoor, which is showing Version 1.6 on the motherboard. I can verify that it is an IPQ50xx device.
The IPQ50xx support is coming along nicely, and can be found here:
I have the serial boot log for this device available, but it is too large for a post here. I'm sorting through getting a hardware page up on the wiki for this device. I will be working to get it up and running once the ipq50xx work makes it down to main.
