Flashing
| NOTE: During configuration or flashing a device, the only things that should be hooked to the device is the computer and power. |
Flashing OpenWrt
| Devices with Broadcom WiFi chipsets have limited OpenWrt supportability (due to limited FLOSS driver availability for Broadcom chips). Consider this when choosing a device to buy, or when deciding to flash OpenWrt on your device because it is listed as supported. See Broadcom WiFi for details. |
Subtarget: generic
Package architecture: arm_cortex-a9
Supported Since Commit
Support started version: 23.05.0
Current supported version: 24.10.4
Installation method(s):
see git-commit
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!
