Meraki MR26 is an EOL wireless access point featuring a
PoE ethernet port and two dual-band 3x3 MIMO 802.11n
radios and 1x1 dual-band WIFI dedicated to scanning.
Thank you Amir for the unit and PSU.

SERIAL:
WARNING: The serial port needs a TTL/RS-232 3V3 level converter!
The Serial setting is 115200-8-N-1. The board has a populated
right angle 1x4 0.1" pinheader.
The pinout is: VCC (next to J3, has little white arrow), RX, TX, GND.
This flashing procedure for the MR26 was tested with firmware:
"22-143410M-gf25cbf5a-asa".
U-Boot 2012.10-00063-g83f9fe4 (Jun 04 2014 - 21:22:39)
A guide how to open up the device is available on the wiki:
<https://openwrt.org/toh/meraki/mr26>
Notes:
- The WIFI do work to a degree. Limited to 802.11bg in the 2.4GHz band.
- the WIFI macs are made up.
0. Create a separate Ethernet LAN which can't have access to the internet.
Ideally use 192.168.1.2 for your PC. The new OpenWrt firmware will setup
the network via DHCP Discovery, so make sure your PC is running
a DHCP-Server (i.e.: dnsmasq)
'# dnsmasq -i eth# -F 192.168.1.5,192.168.1.50
Download the openwrt-meraki-mr26 initramfs file from openwrt.org and
rename it to something simple like mr26.bin. Then put it into the tftp's
server directory.
1. Disassemble the MR26 device by removing all screws (4 screws are located
under the 4 rubber feets!) and prying open the plastic covers without
breaking the plastic retention clips. Once inside, remove the plastic
back casing. Be careful, there some "hidden" retention clips on both
sides of the LAN port, you need a light to see those. Next, you want to
remove all the screws on the outer metal shielding to get to the PCB.
It's not necessary to remove the antennas!
2. Connect the serial cable to the serial header and Ethernet patch cable
to the device.
4. Before connecting the power, get ready flood the serial console program
with the magic: xyzzy . This is necessary in order to get into the
u-boot prompt. Once Ready: connect power cable.
5. If you don't get the "u-boot>" prompt within the first few seconds,
you have to disconnect and reconnect the power cable and try again.
6. In the u-boot prompt enter:
setenv ipaddr 192.168.1.4
setenv serverip 192.168.1.2
tftpboot ${meraki_loadaddr} mr26.bin; bootm
this will boot a in-ram-only OpenWrt image.
7. Once it booted use sysupgrade to permanently install OpenWrt.
To do this: Download the latest sysupgrade.bin file and move
it to the device. Then use sysupgrade *sysupgrade.bin to install it.
WARNING: DO NOT DELETE the "storage" ubi volume!

Bumping max frame size has significantly affected network performance.
It was done by upstream commit that first appeared in the 5.7 release.
This change bumps NAT masquarade speed from 196 Mb/s to 383 Mb/s for the

* Set IPv4 address of the computer to 192.168.1.2 subnet 255.255.255.0.
* Head to http://192.168.1.1.
* Reset NVRAM.
* Upload the OpenWrt image.
CFE bootloader may reject flashing the image due to image integrity check.
In that case, follow the instructions below.
* Rename the OpenWrt image as firmware.trx.
* Run a TFTP server and make it serve the firmware.trx file.
* Run the URL below on a browser or curl.

List of supported formats grew over time and implementation got a bit
messy. There are multiple functions with format-specific parameters and
commands.
Refactor it by making platform_identify() setup all required info right
after detecting firmware format. This simplifies formats handling in
platform_other_check_image() and platform_do_upgrade() a lot.
This has been tested on:
1. SmartRG SR400ac (TRX): non-NAND sysupgrade
2. Netgear R8000 (CHK): NAND aware and standard sysupgrade-s
3. D-Link DIR-885L (Seama): NAND aware and standard sysupgrade-s
