If FCC is correct then its supportable.
All QCA HW:
IPQ8068, its a IPQ8064 v2.0 based SoC
QCA9889
QCA9992
Some Spansion NAND etc

Hey,
Could you take a picture with the serial pins you used to get the bootlog?
Thanks

Sure, a coworker has the physical setup so sorry for the delay. The connector in question is J3, to which we’ve soldered on a pin header — it will be just pads on other devices.

Yup, got a bootlog too, thanks !
Did you got anything new about the boot interruption ?

I asked Meraki about the U-Boot source code. It's available there: https://0x0.st/iwNP.bz2
It seems the stop str is still "xyzzy", but I didn't manage to go further than that.

Is this usable in a release state?

Any updates on the MR42? I have recently come across a large number of them and I would be very interested in getting openwrt installed on them, to the point where I would consider supplying a unit to some able body.
I also am interested. I have a few also from a dead company. I like to help with this project
what are the serial parms? I can only get garbage on putty trying common speeds and data and parity
so the baudrate was 115200
and xyzzy during the boot got a pound prompt
will the mr33 binaries work on the 42's ?
I'd like to help too, just got one some days ago, and hardware-wise seems promising, way better than what I'd get on a general electronics shop, and if we can get it run I could do a comparative test between mr42 and mr33 (which is my current ap of my home)
No, while the MR33 is IPQ4029 based (e.g. OpenWrt target ipq40xx) the MR42 is IPQ8068 based (e.g. OpenWrt target ipq806x).
Seeking OpenWrt Gurus!
Judging from this thread there seems to be quite a lot of interest around getting OpenWrt running on the MR42. I have a pretty solid engineering background and want to help out and learn more on how to do this. I have access to basic stuff like soldering equipment and serial-port dongles etc. If someone could offer some mentor-ship I will put the hours in!
PM me please!
I also volunteer to help. I have a decent workbench. I have added a header and can get to root on my test ME42. I have 12 or so to convert once there is a solution.

Now we have U-Boot source code. https://0x0.st/iwNP.bz2
Can we compile openwrt compatibile u-boot from this? This device does not have the brick that we see on MR33. So far we still can intrerupt boot with "xyzzy".
Also, it looks like there is a firmware recovery procedure that works on MR42 too.
Quote from here:
There's a reset button between the ethernet ports. Hold the reset button down, during boot, until the led starts blinking white. At this stage clicking the button will toggle the led, blue or red. Once "selected", just wait and it'll continue booting. Blue is for the "recovery/diagnostic" firmware and red is the Meraki one.
What do i have on my MR42 ?

^ 
does this mean you have gotten openwrt installed and running? 
No. Looks like that recovery mode is actually a fork of openwrt, some older version.
What i really don't know if we can have fully openwrt installed from here.
Hi
I also managed to get a hold on an MR42; is there any way to help in order to try to install OpenWRT on this ?
