Browse files Browse the repository at this point in the history 
Hardware
========
SOC: MediaTek MT7986
RAM: 512MB DDR3
FLASH: 256MB SPI-NAND
WIFI: Mediatek MT7986 DBDC 802.11ax 2.4/5 GHz 4T4R
ETH: MediaTek MT7530 Switch (LAN)
MaxLinear GPY211C 2.5 N-Base-T PHY (WAN)
MaxLinear GPY211C 2.5 N-Base-T PHY (LAN)
UART: 3V3 115200 8N1 (Do not connect VCC)
USB 3.1

Installation
============

Download the OpenWrt initramfs image. Copy the image to a TFTP server
reachable at 192.168.1.70/24. Rename the image to TUF-AX6000.bin.

Connect to the serial console, interrupt the auto boot process by
pressing '4' when prompted or press '1' and set client IP, server
IP and name of the image.

yOU don't need to open the case or even soldering anything.
use three goldpin wires, remove their plastic cover and connect
them to the console pinout via the case holes.

You can see three holes
From Bottom: RX, TX, Ground - partially covered

Download & Boot the OpenWrt initramfs image.

In case of option '4'
$ setenv ipaddr 192.168.1.1
$ setenv serverip 192.168.1.70
$ tftpboot 0x46000000 TUF-AX6000.bin
$ bootm 0x46000000

In case of option '1'
1: Load System code to SDRAM via TFTP.
Please Input new ones /or Ctrl-C to discard
Input device IP (192.168.1.1) ==:
Input server IP (192.168.1.70) ==:
Input Linux Kernel filename (TUF-AX6000.trx) ==:

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

$ sysupgrade -n <path-to-sysupgrade.bin>

Missing features
================

2.5Gb LAN port LED is ON during boot or when the LAN cable is disconnected

The cover yellow light is not supported. (only blue one)
