OpenWrt for CMCC RAX3000Q

This is a fork of the official OpenWrt project with support for CMCC RAX3000Q.

✅ Current Status

The following features are working:

• WiFi
• Ethernet switch
• SPI NAND
• LEDs
• Reset button

🚧 Work in Progress

• System upgrade (firmware upgrade) is still under development
• MAC address for WAN LAN WiFi

⚠️ Known Limitations

• The device has only 256MB RAM, which is insufficient for running LuCI together with the full ath11k driver.(less than 20M free)
• Frequent OOM (Out-Of-Memory) conditions may occur under normal usage.

Disclaimer

This fork is intended for experimental and development purposes only.

Flashing Guide

This guide explains how to flash OpenWrt on the RAX3000Q router. Please follow each step carefully to avoid bricking your device.

---

Prerequisites

• Backup all important data, especially the ART partition, as flashing U-Boot will modify the partition table and erase unbacked data.
• UART access
• .ubi firmware file for OpenWrt.

---

Steps

1. Connect UART and interrupt U-Boot

   • Open serial console (115200n8)
   • Power on and stop autoboot

2. Configure network

   • Connect PC via Ethernet
   • Set static IPv4:

     192.168.10.19 / 255.255.255.0
     

3. Start TFTP server

   • Place <firmware>.ubi in TFTP root
   • Start server

4. Load firmware in U-Boot

tftpboot 192.168.10.19:<firmware>.ubi

5. Flash

flash rootfs

6. Reboot

reset

Notes

• Ensure the .ubi file matches your device model.
• Do not interrupt the flashing process.
• Always keep a backup of important partitions, particularly the ART partition, for wireless calibration.

OpenWrt Project is a Linux operating system targeting embedded devices. Instead of trying to create a single, static firmware, OpenWrt provides a fully writable filesystem with package management. This frees you from the application selection and configuration provided by the vendor and allows you to customize the device through the use of packages to suit any application. 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.

Download

Built firmware images are available for many architectures and come with a package selection to be used as WiFi home router. To quickly find a factory image usable to migrate from a vendor stock firmware to OpenWrt, try the Firmware Selector.

• OpenWrt Firmware Selector

If your device is supported, please follow the Info link to see install instructions or consult the support resources listed below.

An advanced user may require additional or specific package. (Toolchain, SDK, ...) For everything else than simple firmware download, try the wiki download page:

• OpenWrt Wiki Download

Development

To build your own firmware you need a GNU/Linux, BSD or macOS system (case sensitive filesystem required). Cygwin is unsupported because of the lack of a case sensitive file system.

Requirements

You need the following tools to compile OpenWrt, the package names vary between distributions. A complete list with distribution specific packages is found in the Build System Setup documentation.

binutils bzip2 diff find flex gawk gcc-6+ getopt grep install libc-dev libz-dev
make4.1+ perl python3.7+ rsync subversion unzip which

Quickstart

1. Run ./scripts/feeds update -a to obtain all the latest package definitions defined in feeds.conf / feeds.conf.default

2. Run ./scripts/feeds install -a to install symlinks for all obtained packages into package/feeds/

3. Run make menuconfig to select your preferred configuration for the toolchain, target system & firmware packages.

4. Run make to build your firmware. This will download all sources, build the cross-compile toolchain and then cross-compile the GNU/Linux kernel & all chosen applications for your target system.

Related Repositories

The main repository uses multiple sub-repositories to manage packages of different categories. All packages are installed via the OpenWrt package manager called opkg. If you're looking to develop the web interface or port packages to OpenWrt, please find the fitting repository below.

• LuCI Web Interface: Modern and modular interface to control the device via a web browser.

• OpenWrt Packages: Community repository of ported packages.

• OpenWrt Routing: Packages specifically focused on (mesh) routing.

• OpenWrt Video: Packages specifically focused on display servers and clients (Xorg and Wayland).
