Howdy, all.
I’m looking at implementing OpenWrt on my RB1100AHx4 but I don’t see any builds for this architecture from MikroTik.
Is an existing OpenWrt platform compatible with the AL21400? If not, it seems like the v1.2 patch in Building your own OpenWRT image doesn’t mention ARM…
Does anyone have OpenWrt running on their AHx4?
Thanks, Fred
I did a little more digging and found the following info:
I think I’ll just start trying to build and see what happens but, if anyone has any experience with this, any hints, tips, or link to the pre-built .tgz would be appreciated! 
Why would you run OpenWRT on the RB1100? Is is not performing? Is it not conforming your expectations?
I need to connect to a 3rd party over OpenVPN with UDP. Looks like only OpenVPN with TCP is supported and, since there is no plan to support OpenVPN with UDP, using Metarouter was mentioned as an option.
If you get it working, we’d love to know! I’m looking closely at RB1100 devices as my next Mikrotik. Thanks.

Hi Blackdeath,
NR in-a-box for AR71xx should be compatible with Atheros QCA9533-BL3A, based on the openwrt document for TP-Link TL-WR841ND, but we didnt test it.
Thanks,

Hi, KevinZ. Was this reply in the right thread? There’s no Blackdeath in this thread and it looks like Atheros 9533 are in hAP/mAP lites and the PowerBox (but this thread was about ARM). I want to make sure another thread isn’t accidentally ignored.
There is no MetaROUTER for RouterOS ARM platforms. Do you see a “/metarouter” tree on the RouterOS CLI for your AHx4, or a “MetaROUTER” config option within Winbox for this model? Thought not. You might be able to eventually build OpenWRT for the SoC in the 1100AHx4, but it is going to have to run bare-metal on the hardware, not virtualized.
The “v1.2” patch in the Wiki docs is YEARS old, and the “1100” model they reference is the single-core PPC version, not the dual-core PPC and certainly not the quad-core ARM one. None of the code in that patch is going to be of any use to anyone in bringing OpenWRT to this model. And besides, the patches that MT released for the 1100 way back when were only useful insofar as building an OpenWRT image that could boot within RouterOS’ MetaROUTER, not bare-metal.
Without simply waiting for OpenWRT/LEDE developers to officially support this hardware, your best bet is to grab the latest RouterOS GPL kernel patches from MikroTik, and then work to integrate them into OpenWRT yourself. And, again, to be clear, all that this gets you is a build of OpenWRT that you can use on an 1100AHx4 INSTEAD of RouterOS, not in parallel with it.

Hello! I’m having RB4011iGS+RM, it has AL21400 processor too…
Can You point me how to get such patches to take approach to this?
You have to email MIkrotik support and request GPL code/patches. You even had to pay shipping fee because they insisted on sending you a CD/DVD.
That seems to have changed, see: https://forum.mikrotik.com/viewtopic.php?f=2&t=100803
But you have to directly ask support for it, there is no download link anywhere…
Here you are at Mikrotik (RouterBoard + Router OS) forum. Not RouterBoard with 3rd party firmware, this can be your responsibility!
I am also interested.
@Ingdaka bro relax it’s a good thing the OpenWRT comes in handy too often. He is just asking if someone is already knowledgeable about it. He is not asking you to support it in an enterprise or telecom scenario. Don’t attack. Rather be helpful in any way.
The best platform to ask https://t.ly/JMIDS
That’s a different crowd to talk to over there, here as you can see, a more enterprise crowd of different people, who have made the choice, to be more serious, is available.
Do you want to talk to friendly professionals or edgy hackers potentially gangsters?
