OpenWrt for the Digineo AC1200 Pro

This repository contains the material needed to build the official OpenWrt firmware image for our AC1200 Pro router.

Obtaining pre-built firmwares

You'll find the latest firmware images on the Github releases page.

You may also use the OpenWrt images found here (look for the zbt-wg3526-32M files). Please note that these images only contain the bare essentials, and not all device features may be available without manually installing further packages.

Building firmware manually

To build the firmware image, you need to meet some prerequisites.

• You'll need a Linux machine to perform the build. This can be either a physical or a virtual machine.
• Depending on the distribution, you may need to install some dependencies (tools/libraries/etc.). Refer to the OpenWrt wiki on how to get started.
• The building machine requires approx. 12-15 GB free disk space. A powerful CPU and lots of RAM are recommended.

Clone this repository

If you start fresh, get a copy of this repository:

$ git clone --recursive https://github.com/digineo/openwrt-ac1200.git .
$ cd openwrt-ac1200

If you only need to fetch updates, do the following:

$ cd /path/to/openwrt-1200
$ git pull
$ git submodule update --init

Building the image

In the source checkout directory, run this command:

$ make all

When it finishes, you'll find the image files in ./firmware:

• use openwrt-ramips-mt7621-zbt-wg3526-32M-initramfs-kernel.bin to downgrade or perform a factory reset, and
• use openwrt-ramips-mt7621-zbt-wg3526-32M-squashfs-sysupgrade.bin to upgrade to a newer version

Warning: Do not use the sysupgrade file to perform a version downgrade. This is not supported.

Flashing the router

via LuCI

1. Login to your router (by default http://192.168.1.1)
2. Go to System → Backup/Flash firmware.
3. Under "Flash new firmware image", select the image file.
4. Click on the "Flash image..." button.
5. Click in "Proceed".
6. Wait for the process to finish. This will take a few minutes.

via SSH

Alternatively, you may copy the image file via scp onto your device, and perform a manual sysupgrade:

$ scp /path/to/kernel-or-sysupgrade.bin root@192.168.1.1:/tmp/
$ ssh root@192.168.1.1
# sysupgrade /tmp/kernel-or-sysupgrade.bin

This will additionally print some diagnostics, before finally restarting the device. Do not terminate the SSH connection while sysupgrade is running!
