OpenWrt Forum Archive

Hi all. The Ubiquiti UniFi Pro (UAP-PRO) just started shipping not too long ago, and I figured I'd take a stab at getting OpenWRT on it.

From what I can tell, it's an AR9344 board, 128mb RAM, 16mb flash. The serial console runs on it for only the boot loader, so I can't get the full output from the kernel loading, but here's what I get from it's dmesg:

Fully expecting it to not work, I tried just building the lastest version and seeing what happens. When I try flashing it, I get this:

Header MAGIC 'OPEN'
Current: BZ.ar934x.v2.3.2.946.120430.1858

New ver: UBNTXM.ar7240.v6.0.0-OpenWrt-r32576
Invalid version 'UBNTXM.ar7240.v6.0.0-OpenWrt-r32576'

The CPU appears to be supported in OpenWRT, since the TP-Link TL-WDR4300 uses the same platform (AR9344). So this may just be as easy as changing the string in the firmware. What I'm not sure of is exactly WHAT to change. fwupdate is clearly checking the string, but I'm not sure what bits it cares about. I'm guessing the cpu type needs to be exactly the same, but can someone verify this before I start monkeying with the "target/linux/ar71xx/image/Makefile" file and kill the device?

Thanks!
