Build and install

Requirements

Build: riptide_wave's build of CC
Method: TFTP Installation Setup
Serial interface (pinout details below)

Step by Step Flashing Guide

Read the full guide before proceeding and make sure you understand the implications of the flash commands. Any error is likely to brick your device. At this time there is no way to recover from a bricked MR16 short of desoldering the SOIC and reprogramming.

Built on Ubuntu 14.04 LTS, this guide assumes you have a basic working knowledge of the command line and know your way around permissions, copying files etc.

Links are provided as additional reading and guidance.

To boot from TFTP: openwrt-ar71xx-generic-mr16-initramfs-uImage.bin
To flash to the device: openwrt-ar71xx-generic-mr16-kernel.bin & openwrt-ar71xx-generic-mr16-rootfs-squashfs.bin

  • Configure TFTP server and place the above files in the /tftp directory.
  • Make sure you have a serial connection to your MR16 using the below hook up. Guide was put together using one of these.
  • Start the TFTP server on your machine and connect the ethernet cable to the 10/100/1000 port on the MR16.
  • Power up and interrupt the boot sequence to take you to the boot loader.
  • Run the following command on the MR16 terminal:

tftpboot 0x81000000 openwrt-ar71xx-generic-mr16-initramfs-uImage.bin; bootm

  • Test boot, login, and configure connectivity. If happy/successful, move on.
  • Reboot the MR16 and interrupt the boot loader once more. To install follow the flash commands below to commit the images to the MR16. *Warning this is irreversible and WILL destroy the MR16's factory shipped image*
  • Check, double check and probably triple check each of the commands to ensure they are EXACTLY as below before hitting enter on each.

Flash Commands

Commands are ran in uboot. Source.

tftpboot 0x80010000 openwrt-ar71xx-generic-mr16-kernel.bin;erase 0xbfda0000 +0x240000;cp.b 0x80010000 0xbfda0000 0x240000
tftpboot 0x80010000 openwrt-ar71xx-generic-mr16-rootfs-squashfs.bin;erase 0xbf080000 +0xD20000;cp.b 0x80010000 0xbf080000 0xD20000
setenv bootcmd bootm 0xbfda0000; saveenv; boot

LEDE - Setting hardware MAC Address

Note that as of 2016-10-26, users of LEDE on the MR12 and MR16 can now properly set their hardware MAC address to prevent MAC conflicts, or needing to set this with every reset. To verify if your installed firmware supports this, run cat /proc/mtd | grep mac and if you see a "mac" partition like the example below, you can then follow the below steps to set your MAC address.

root@lede:~# cat /proc/mtd | grep mac
mtd5: 00010000 00010000 "mac"

If you see the "mac" partition like the above example you can continue, otherwise the following process will not work and MAY BE DAMAGING to your device.

To set your MAC, do the following.

  • Get your MAC from the bottom of the device. In this example, we use 00:18:0a:33:44:55
  • Convert your mac to somthing we can use with hex & echo. SO with the above mac, we would change it to:
  • \x00\x18\x0a\x33\x44\x55
  • With this, we can now erase our mac partition and set the MAC address using the following commands:
  • mtd erase mac
    echo -n -e '\x00\x18\x0a\x33\x44\x55' > /dev/mtd5
    sync && reboot
  • Once done your board will reboot, and should have the correct MAC set on the eth and wireless interfaces.

MAC Address

If you have 2 or more MR16's in your network, you'll need to set the Ethernet MAC address as well as the BSSID's for both radios. The MAC address on a sticker in the AP near the ethernet connector. It is in the format of

MAC: 00:18:0A:xx:xx:xx (where 00:18:0A is the OUI owned by Meraki/Cisco)

The BSSID's are derived from it directly:

  • 2.4GHz 00:18:0A:xx:xx:xx (same as MAC)
  • 5.0GHz 02:18:1A:xx:xx:xx (Derived from MAC, local administered (02:…)

This is the exact same as Stock Meraki MR16 uses. This cannot (in Chaos Calmer) be assigned with LuCi, and needs to be set manually.

The files below are representative for my network (with confidential info removed), but the only things you need to set are the "option macaddr" parameters.

File: /etc/config/network

WARNING: Using LuCI WILL delete the MAC Address!

config interface 'loopback'
	option ifname 'lo'
	option proto 'static'
	option ipaddr '127.0.0.1'
	option netmask '255.0.0.0'

config globals 'globals'
	option ula_prefix 'xxxx:xxxx:xxxx::/48'

config interface 'lan'
	option ifname 'eth0'
	option force_link '1'
	option type 'bridge'
	option proto 'dhcp'
	option vendorid 'meraki'
	option delegate '0'
	option macaddr '00:18:0A:xx:xx:xx'
Note I just used DHCP. My router (a pfSense device, but of cause can also be a OpenWrt device) is set up to supply a static IP address for the MAC address of my Access Point.

File: /etc/config/wireless

The MAC address in this file looks like it does NOT get changed by LuCI.
