Adding support for TP-Link Archer AX80 EU version, I actually installed it but needs some small work

Also some additional info here. This is what happens on the logs when you plug in the ports. As said on the labels on the device, lan1-2-3 and 1GBPS WAN/LAN port:

PHYSICAL LAN 2 PLUGGED:
[  479.526607] br-lan: port 4(lan3) entered blocking state
[  479.539713] br-lan: port 4(lan3) entered forwarding state

PHYSICAL LAN 1 PLUGGED:
[  499.679190] br-lan: port 3(lan2) entered blocking state
[  499.692299] br-lan: port 3(lan2) entered forwarding state

1 GBPS WAN/LAN PORT PLUGGED:
[  536.903863] br-lan: port 2(lan1) entered blocking state
[  536.916964] br-lan: port 2(lan1) entered forwarding state

this is what happens when you plug in port PHYSICALLY TAGGED as LAN3(but it's the last port actually so). At first, nothing happens in the logs, I plugged that and unplugged the LAN3 port and nothing happened. It's just that it doesn't really work. But, the moment I unplug that and plug it onto working ports of the router, it immediately gives this message in the logs and reboots. And this is that logs:

I also mounted the tp_data again, it doesn't auto mount it. I think I am gonna need some recompiling for wifi. Btw can I compile for 24.10.4?

23

I think the 1gbps lan/wan port needs to be lan only, the 2,5gb port acts as wan. And looks like the ports are wrongly assigned.

Edit: I think the last port is also assigned as a port 4(lan3), that’s why maybe it’s rebooting.

24

I thinks it’s also better to stay on snapshot for now, because it’s not stable yet.

25

Ok when I plug the each ports individually, this is more understandable:

26

So looking at it, 2.5gb wan is eth0, 1gb wan/lan will be lan0 and lan only, and then you have lan1,2,3.

You need to change port assingment in dts, and see what works.

27

Sadly I don't know how to change port assignment in dts, but I'll try.

28

You need to edit this portion:

ports {
                                #address-cells = <1>;
                                #size-cells = <0>;

                                port@0 {
                                        reg = <0>;
                                        label = "lan0";
                                };

                                port@1 {
                                        reg = <1>;
                                        label = "lan1";
                                };

                                port@2 {
                                        reg = <2>;
                                        label = "lan2";
                                };

                                port@3 {
                                        reg = <3>;
                                        label = "lan3";
                                };

                                port@6 {
                                        reg = <6>;
                                        label = "cpu";
                                        ethernet = <&gmac0>;
                                        phy-mode = "2500base-x";

                                        fixed-link {
                                                speed = <2500>;
                                                full-duplex;
                                                pause;
30

Ok I changed the DTS like this, but now guess what? LAN3 works this time, but LAN2 doesn't:

ports {
		#address-cells = <1>;
		#size-cells = <0>;

		/* 1G WAN/LAN olarak etiketli fiziksel jack */
		port@0 {
			reg = <0>;
			label = "lan0";     /* istersen "wan_lan" da diyebilirsin */
		};

		/* Fiziksel LAN1 */
		port@1 {
			reg = <1>;
			label = "lan1";
		};

		/* Fiziksel LAN2 */
		port@2 {
			reg = <2>;
			label = "lan2";
		};

		/* Bazı AX80 revizyonlarında port3 kullanılmıyor olabilir.
		   Eğer gerçekten bağlı ise label ver; değilse disable et. */
		port@3 {
			reg = <3>;
			status = "disabled";   /* ihtiyaca göre kaldıralım/aktif edelim */
			/* label = "lanX";  // eğer bağlıysa bunu açıp doğru etiketi ver */
		};

		/* Fiziksel LAN3 — sende şu an hiç log vermeyen port büyük ihtimalle bu */
		port@4 {
			reg = <4>;
			label = "lan3";
		};

		/* CPU uplink — 2.5G */
		port@6 {
			reg = <6>;
			label = "cpu";
			ethernet = <&gmac0>;
			phy-mode = "2500base-x";
			fixed-link {
				speed = <2500>;
				full-duplex;
			};
		};
	};
31

I only added initial support to git now. Nothing unstable. Just tp_data auto mount, then wifi eeprom
file symlinking. Other than that the file is very similiar to US version.

Things are going good. work, MAC addresses are right this time. Thanks for @HateTM work in github.
What's working:
ALL LAN'S and 2.5G WAN work and 1G WAN/LAN too.
LEDS are kinda wrong, Wifi led is on even though it's actually off
Mac addresses are right, tp_data is mounted rightfully

33

Now you could give some installation instructions ?

34

Tbh one of my friends succeeded with this method without opening: https://github.com/aaronsvk/CVE-2022-30075/tree/main
But I couldn't do it. But he said he logged into TP-Link Tether app, maybe it triggered something. But, this scipt injects into DDNS on the ax80 stock interface. Maybe, if you can instead inject it to some wifi led buttons code or something, then pressing the button, it could of work. If you can, go ahead.
I used UART, UART is above the CPU there is 4 slots. From left to right: VCC(don't plug this); GND;RX;TX or might be GND;TX;RX try both.
Installation (UART)
Place OpenWrt initramfs image on tftp server with IP 192.168.1.2

Attach UART, switch on the router and interrupt the boot process by pressing 'Ctrl-C'

Load and run OpenWrt initramfs image:


      tftpboot initramfs-kernel.bin
      bootm

!!Attention!! is very important! After entering OpenWrt, please set / update the environment variables. But, this might not be that important, check with fw_printenv on ssh, if you have same records as these lines, then you don't need to apply these. Device doesn't have secure boot so.


fw_setenv bootargs "ubi.mtd=ubi0 console=ttyS0,115200n1 loglevel=8 earlycon=uart8250,mmio32,0x11002000 init=/etc/preinit"
fw_setenv mtdids "spi-nand0=spi-nand0"
fw_setenv mtdparts "spi-nand0:2M(boot),1M(u-boot-env),50M(ubi0),50M(ubi1),8M(userconfig),4M(tp_data),8M(mali_data)"
fw_setenv tp_boot_idx 0

Then scp the squashfs image, then run 'sysupgrade -n' with the sysupgrade OpenWrt image from console or Luci WebUI.

35

When will be the device accepted? Actually its been working for 3 days straight, no problems. Dont mind the uptime, electrical outage happened. Also most checks have passed. Even re-compiled the firmware to use zapret too. Even the USB works fine.

Anywhere from soon to never.

Did you read https://openwrt.org/submitting-patches ?

Everything seems to be in order. No problems.

Hi. Thanks for adding support for this device, I would very much like to see it merged soon.

I am not a developer, nor have a github A/C, but I think there are some issues in your commit message:

  1. "mediatek: filogic: add TP-Link Archer AX80 v1 (EU) support" should appear in your PR title, not just in content head.

  2. about the hardware specification, from what I've gathered from the web, I think it's more like the Mercusys MR90X v1 than the Tp-link Archer AX80 v1 (US/RU): RAM is integrated inside SoC MT7986B, Wlan chip is MT7975, power supply is 12V 2A. But I could be wrong, UART boot log should reveal those.
