Christoph Krapp 50d9ca6e5a mediatek: filogic: add support for ASUS RT-AX52 
Hardware
--------
SOC:   MediaTek MT7981b
RAM:   256MB DDR3
FLASH: 128MB SPI-NAND (Winbond W25N01GV)
WIFI:  Mediatek MT7981b DBDC 802.11ax 2.4/5 GHz
ETH:   MediaTek MT7531 Switch
UART:  3V3 115200 8N1 (Pinout silkscreened / Do not connect VCC)

Installation
-----------------------------------------------------------
Vendor-UI Method
-----------------------------------------------------------
1. Download the OpenWrt initramfs.trx image.

2. Connect the PC via LAN to one of the yellow router ports and wait
   until your PC to get a DHCP lease.

3. Browse to http://192.168.50.1

4. If your router is brand new, finish the setup process and log into
   the Web-UI.

5. Navigate to Administration -> Firmware Upgrade and upload the
   downloaded OpenWrt image.

6. Wait for OpenWrt to boot. Transfer the sysupgrade image to the device
   using scp and install using sysupgrade.

   $ sysupgrade -n <path-to-sysupgrade.bin>
-----------------------------------------------------------
TFTP Method
-----------------------------------------------------------
1. Download the OpenWrt initramfs image. Copy the image to a TFTP server
   reachable at 192.168.1.70/24. Rename the image to rtax52.bin.

2. Connect the PC with TFTP server to the RT-AX52.
   Set a static ip on the ethernet interface of your PC.
     (ip address: 192.168.1.70, subnet mask:255.255.255.0)
  Conect to the serial console,
   interrupt the autoboot process by pressing '4' when prompted.

3. Download & Boot the OpenWrt initramfs image.

   $ setenv ipaddr 192.168.1.1
   $ setenv serverip 192.168.1.70
   $ tftpboot 0x46000000 rtax52.bin
   $ bootm 0x46000000

4. Wait for OpenWrt to boot. Transfer the sysupgrade image to the device
   using scp and install using sysupgrade.

   $ sysupgrade -n <path-to-sysupgrade.bin>
---------------------------------------------------------------------------
Revert to stock firmware:
1: Download the rt-ax52 firmware from ASUS official website. Save
   the firmware to tftp server directory and rename to RT-AX52.trx

2: Connect the PC with TFTP server to the RT-AX52.
   Set a static ip on the ethernet interface of your PC.
     (ip address: 192.168.1.70, subnet mask:255.255.255.0)

3: Conect to the serial console,  power on again,  interrupt the
   autoboot process by pressing '4' when prompted.
  $: ubi remove linux
  $: ubi remove jffs2
  $: ubi remove rootfs
  $: ubi remove rootfs_data
  $: ubi create linux 0x45fe000
  $: reset

  Then the dut will reboot,interrupt the autoboot process by
  pressing '2' when prompted.
       2: Load System code then write to Flash via TFTP.
       Warning!! Erase Linux in Flash then burn new one. Are you sure?(Y/N)
       $: enter y
  you will see the follow, type enter directly:
       Input device IP (192.168.1.1) ==:
       Input server IP (192.168.1.70) ==:
       Input Linux Kernel filename (RT-AX52.trx) ==:

4: wait for the device run up

OpenWrt logo

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.

Sunshine!

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.

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:

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).
