OpenWrt for Amlogic TV Boxes

View Chinese description | 查看中文说明

The OpenWrt Project is a Linux router operating system targeting embedded devices. Instead of trying to create a single, static firmware, OpenWrt provides a fully writable filesystem with package management. Allows you to freely choose the software package you need to customize your router system. For developers, OpenWrt is the framework to build an application without having to build a complete firmware around it; for users this means the ability for full customization, to use the device in ways never envisioned. It has more than 3000+ standardized application packages and a very rich third-party plug-in support, so you can easily replicate the same setup on any supported device.

Now you can replace the Android TV system of the TV Boxes with the Amlogic chip with the OpenWrt system, making it a powerful router. This project supports one-stop complete compilation of github.com (compiling from custom software packages to packaging firmware, all in one stop at github.com). Support localized packaging (firmware packaging in local Ubuntu and other environments). including OpenWrt firmware install to EMMC and update related functions. Support Amlogic s9xxx TV Boxes are a311d, s922x, s905x3, s905x2, s905l3a, s912, s905d, s905x, s905w, s905, etc. such as Belink GT-King, Belink GT-King Pro, UGOOS AM6 Plus, X96-Max+, HK1-Box, H96-Max-X3, Phicomm-N1, Octopus-Planet, Fiberhome HG680P, ZTE B860H, etc.

The latest version of the OpenWrt firmware can be downloaded in Releases. Welcome to use Fork for personalized OpenWrt firmware configuration. If you like it, Please click the Star.

Use GitHub Actions to build

You can modify the configuration file in the router-config directory and .yml file, customize the OpenWrt firmware, and complete the packaging online through Actions, and complete all the compilation of OpenWrt firmware in github.com One-stop.

1. Personalized plug-in configuration in router-config directory. Workflows configuration in .yml file.
2. New compilation: Select Build OpenWrt on the Action page. Click the Run workflow button.
3. Compile again: If there is an openwrt-armvirt-64-default-rootfs.tar.gz file in Releases, you do not need to compile it completely, you can directly use this file to build openwrt of different soc. Select Use Releases file to Packaging on the Actions page. Click the Run workflow button.
4. More support: The compiled openwrt-armvirt-64-default-rootfs.tar.gz file is a common file for making various SoC firmware, and it is also suitable for making OpenWrt firmware using unifreq's packaging script. As the pioneer of using OpenWrt and Armbian system in the box, he has supported more devices, such as OpenWrt (qemu version) as used by KVM virtual machine on Armbian system, Allwinner (V-Plus Cloud), and Rockchip (BeikeYun, Chainedbox L1 Pro), and Amlogic series, etc. For details on the packaging method, please refer to his source code repository description. In Actions, you can use packaging-openwrt-for-qemu-etc.yml to call his packaging script to make more firmware.

Resource Description

When making an OpenWrt system, the kernel and u-boot files used are the same files used to make an Armbian system. In order to avoid repeated maintenance, the relevant content is classified and placed in the corresponding resource repository, and it will be automatically downloaded from the relevant repository when it is used.

The kernel / u-boot and other resources used by this system are mainly copied from the project of unifreq/openwrt_packit, Some files are shared by users in Pull and Issues of amlogic-s9xxx-openwrt / amlogic-s9xxx-armbian / luci-app-amlogic / kernel and other projects. unifreq opened the door for us to use OpenWrt in TV Boxes, and was deeply influenced by him. My firmware has inherited his consistent standards in production and use. To thank these pioneers and sharers, I have recorded them in CONTRIBUTORS.md. Thanks again everyone for giving new life and meaning to the Boxes.
