Installation

→ Install OpenWrt (generic explanation)

Installation process

ath79 (OpenWrt Snapshot and 20 onwards)

  • Requires TFTP server at 192.168.1.101, w/ initramfs & sysupgrade Snapshot .bin files above
  • Open shell case and connect a USB to TTL cable to upper serial headers (see beginning of the Tomesh guide for this)
  • Power on the router; connect to U-boot over 115200-baud connection (usu. sudo screen /dev/ttyUSB0 115200)
  • Interrupt U-boot process with <Enter>, and boot OpenWrt initramfs by running:
setenv bootcmd bootm 0xbf0a0000; saveenv;
tftpboot 2000000 <filename-of-initramfs-kernel>.bin;
bootm 2000000;
  • Copy (via scp) sysupgrade .bin to /tmp on MR16
scp <filename-of-sysupgrade> root@192.168.1.1:/tmp

If you get error ash: /usr/libexec/sftp-server: not found: As of OpenSSH 9.0 scp will use the newer SFTP protocol by default which OpenWrt does not support. Use the -O option to force the usage of the (old) secure copy protocol. 

scp -O <filename-of-sysupgrade> root@192.168.1.1:/tmp
  • Run (via serial): sysupgrade /tmp/<filename-of-sysupgrade>.bin

Notes

The manner of storing MAC addresses is different between the ath79 and ar71xx targets; in ath79 it is at 0x66 of the 'config' partition, where the OEM firmware stores it. This config partition is set as read-only. If you are migrating from ar71xx and used the method mentioned above to upgrade, you could use kmod-mtd-rw to add the MAC back in. A no-serial-connection method for doing this is described below.

Again, this may BRICK YOUR DEVICE, so make *sure* to have your serial cable handy.

Migrating from ar71xx to ath79 with no serial connection (from OpenWrt v. <= 19 to OpenWrt v. >= 20)

Migrating directly from ar71xx has not been thoroughly tested, but one method has been used a couple of times with good success, migrating 18.06.2 to a full image produced as of this commit. Please note that these instructions are only for experienced users, and/or those still able to open their device up to flash it via the serial headers should anything go wrong.

1) Install kmod-mtd-rw and uboot-envtools

2) Run insmod mtd-rw.ko i_want_a_brick=1

3) Modify /etc/fw_env.config to point to the u-boot-env partition. See the uboot.config for more details. The file /etc/fw_env.config should contain: 

       # MTD device   env offset  env size    sector size
       /dev/mtd1      0x00000     0x10000     0x10000

4) Run fw_printenv to verify that you can read the U-Boot environment correctly, as per the link above.

5) Run fw_setenv bootcmd bootm 0xbf0a0000 to set a new boot address.

6) Manually modify /lib/upgrade/common.sh's get_image function, from ... 

       cat "$from" 2>/dev/null | $cmd

... to ... 

       (
         dd if=/dev/zero bs=1 count=$((0x66)) ; # Pad the first 102 bytes
         echo -ne '\x00\x18\x0a\x12\x34\x56'  ; # Add in MAC address
         dd if=/dev/zero bs=1 count=$((0x20000-0x66-0x6)) ; # Pad the rest
         cat "$from" 2>/dev/null ; # Push the firmware
       ) | $cmd

During the upgrade process, this will pad the image by 128K of zeroes-plus-MAC-address, in order for the ar71xx's firmware partition -- which starts at 0xbf080000 -- to be instead aligned with the ath79 firmware partition, which starts 128K later at 0xbf0a0000.

7) Copy the sysupgrade image into /tmp, as above

8) Run sysupgrade -F /tmp/<sysupgrade>.bin, then wait

ar71xx (19.07.5 and before)

Note: It is recommended to use the Snapshot ath79 installation instead. 19.07.5 cannot be upgraded to later versions without some hassle.

Note: You may also want to see the Tomesh guide for this installation; it is complete.

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 clipping to the SOIC and reprogramming.

  • 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 U-Boot terminal:

Flash Commands

Commands are ran in uboot. 

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

ar71xx -- Setting hardware MAC Address

Note that as of 2016-10-26, users of ar71xx OpenWrt 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.

	option type 'mac80211'
	option hwmode '11g'
	option path 'pci0000:00/0000:00:11.0'
