RDKB Wi-Fi OpenWRT Feed

New Packages

rbus

• OpenWRT port of RDK-Bus.
• More information in rbus/README.md

easymesh

• Contains Unified-Wifi-Mesh Agent and Controller
• Contains OneWifi

rdkb-ieee1905

• Contains ieee1905 daemon to manage 1905 traffic

Backported packages

avro-c

libmariadb

• Backports newer version that can be downloaded from mirror

Rust (build environment)

• Used to build the rdkb-ieee1905 package
• Not present in OpenWRT 21.0.2
• Only changed to environment gzip and TOOLCHAIN_ROOT_DIR -> TOOLCHAIN_DIR

Local Builds

easymesh

• Custom ONEWIFI_LOCAL_DIR, UWM_LOCAL_DIR, RDK_WIFI_HAL_LOCAL_DIR, and HALINTERFACE_LOCAL_DIR make params have been added to build from a local copy of one or multiple of these repos.
• These can be provided is this method:

make package/easymesh/compile V=sc PKG_HASH=skip PKG_MIRROR_HASH=skip UWM_LOCAL_DIR=~/unified-wifi-mesh ONEWIFI_LOCAL_DIR=~/OneWifi

• These parameters must be given for each operation you want to perform on a local build otherwise it will default to the remote version. For example:

make package/easymesh/clean V=sc PKG_HASH=skip PKG_MIRROR_HASH=skip UWM_LOCAL_DIR=~/unified-wifi-mesh

will run all of the make clean targets in that unified-wifi-mesh directory and will cleanup the OpenWRT build environment for that package.

• Running this on the other hand (without UWM_LOCAL_DIR)

make package/easymesh/clean V=sc PKG_HASH=skip PKG_MIRROR_HASH=skip

will just do the default cleanup operation.

• File changes in the local source directories provided are automatically detected so calling

make package/easymesh/compile V=sc PKG_HASH=skip PKG_MIRROR_HASH=skip UWM_LOCAL_DIR=~/unified-wifi-mesh ONEWIFI_LOCAL_DIR=~/OneWifi

after changing a line in ~/OneWifi will compile with that new code included. The .o files already exist in ~/OneWifi so a full re-compilation does not occur unless you do a clean first.

rdkb-ieee1905

• This should be able to be done by appending USE_SOURCE_DIR=~/rdkb_ieee1905 to the make package/rdkb-ieee1905/compile command however that is un-tested at this time.

RDKB Docker and OpenWRT Configuration Steps

1. OpenWRT Build Instruction

1.1. Building the Base Image

Basic OpenWRT environments setup commands:

Execute below commands to setup and build for the first time:

apt-get update
apt-get install git build-essential gcc binutils libncurses5-dev zlib1g-dev libssl-dev libncursesw5-dev gawk flex bison texinfo subversion gettext libxml2-dev libpcap-dev
apt-get install rsync wget file unzip python3 python3-distutils
apt-get install git openssh-server bridge-utils mariadb-server libmysqlcppconn-dev vim libdbus-1-dev dbus libev-dev libjansson-dev zlib1g-dev libnl-3-dev libnl-genl-3-dev libnl-route-3-dev libavro-dev libssl-dev uuid-dev libreadline-dev iptables golang gcc gdb golang-go cscope exuberant-ctags make
apt-get install ca-certificates
git config --global http.sslVerify false
export FORCE_UNSAFE_CONFIGURE=1

Start openWRT base build for the BPI Mediatek (MT7988) Board

Follow the instruction in the link: BPI Initial build, section Filogic 880/860 WiFi7 Kernel5.4 MP4.0 Release and choose the SKU to build as Filogic880/MT7996.

After the initial build, Ensure .config has the below entries to generate BPI based binary. If not please add these entries in .config.

CONFIG_TARGET_DEVICE_mediatek_mt7988_DEVICE_BPI-R4-SD=y

Then refire the top level build command make V=s PKG_HASH=skip PKG_MIRROR_HASH=skip:

This completes the initial base build for BPI.

NOTE: The base build and the EasyMesh/OneWifi build stages can not be combined! Finish building the base build (complete with the last "refire") then move to section 1.2

1.2. Building EasyMesh and OneWifi on top of the base build

1. In the openwrt folder install this feed

echo "src-git rdkb_wifi https://github.com/bcarlson-dev/rdkb-wifi-feed.git" >> feeds.conf.default
./scripts/feeds update -a
./scripts/feeds install -a -p rdkb_wifi

2. Copy the "golden" config file

cp ./feeds/rdkb_wifi/easymesh/MT7966.config .config

3. Build:

make V=s PKG_HASH=skip PKG_MIRROR_HASH=skip

2. Flashing of Images and Running

After building the images, below are the steps to flash the image:

1. Flash the base build on SD card using balenaEtcher software - mtk-bpi-r4-MP4_1-SD-20241216.img
   or General MediaTek Bin Link: https://drive.google.com/drive/folders/1YVb5-Yw2CGuUtm68cckPYMjlWQq7ebRA?usp=sharing

2. After that upgrade the image using the U-Boot Boot menu and TFTP.

3. Run Tftp server on your Macbook. The built .bin (for e.g. openwrt-mediatek-mt7988-BPI-R4-SD-squashfs-sysupgrade.bin) should be placed in /private/tftpboot on the Macbook

4. This flashes the updated image to the SD card.
