ot-br-openwrt

This project provide scripts to build a Thread border router on openwrt.

Hardware

Hi-Link HLK-7688A: MT7688 580MHz MIPS24KEc, 32MB Flash, 128 MB RAM
nRF52840 RCP: https://openthread.io/codelabs/openthread-hardware#3

Software

Docker development environment
OpenWrt v22.03.5
ot-br-posix @c0897a70b907410d9be87eab16c41910bb14a000
openthread @1203ea6426a906d62a3921b6d4c6a4a6c8e0abde

Initialize development environment

update git submodules:

git submodule update --init
cd /src/ot-br-posix/
git submodule update --init

Note: If you need to use a proxy, uncomment and change the environment configs in docker-compose.yml file .

Install docker and docker-compose, and run:

docker-compose up --build

To enter your docker development machine, run:

docker-compose exec -u docker compiler /bin/bash

Build OpenWrt firmware

Edit /src/openwrt/feeds.conf, using feeds.conf.default as template:

src-git-full packages https://git.openwrt.org/feed/packages.git;openwrt-22.03
src-git-full luci https://git.openwrt.org/project/luci.git;openwrt-22.03
src-git-full routing https://git.openwrt.org/feed/routing.git;openwrt-22.03
