Using

&eth0 {
	status = "okay";

	phy-mode = "rmii";
	mtd-mac-address = <&uboot 0xe0000>;
	phy-handle = <&phy0>;

	fixed-link {
		speed = <100>;
		full-duplex;
	};
};

&eth1 {
	status = "okay";

	phy-mode = "rmii";
	mtd-mac-address = <&uboot 0xe0000>;
	mtd-mac-address-increment = <1>;
	phy-handle = <&phy4>;

/*	fixed-link {
		speed = <1000>;
		full-duplex;
	};*/
};

The part in the dmesg that change is

Using

	phy-mode = "rmii";
	mtd-mac-address = <&uboot 0xe0000>;
	phy-handle = <&phy0>;

	phy-handle = <&phy4>;

/*	fixed-link {

};

The dmesg part thath change

[    1.519898] eth0: Atheros AG71xx at 0xb9000000, irq 4, mode:RMII

In both cases, seems that eth1 it's not detected :thinking:

446

but with this, the lan is still not working ?
ah I didn't saw it, maybe is the same mdio0

&mdio0 {

	phy0: ethernet-phy@0 {
		reg = <0>;
		phy-mode = "rmii";
	};
	phy4: ethernet-phy@4 {
		reg = <4>;
		phy-mode = "rmii";
	};
};

and comment all mdio1

447

if the kernel is uncompressed I can run it from memory with exec, I'll see about the whole initramfs image

448

successfully booted an initramfs image and I have this

[    0.426412] PCI host bridge /ahb/apb/pcie-controller@180c0000 ranges:

the same is with

&pcie0 {
        status = "okay";

        ath9k: wifi@0 {
                reg = <0x0000 0 0 0 0>;
                #gpio-cells = <2>;
                gpio-controller;
                qca,no-eeprom;
        };

};

or just

&pcie0 {
        status = "okay";
};

but no signal after powerup

root@OpenWrt:/# cat /etc/config/wireless

config wifi-device 'radio0'
        option type 'mac80211'
        option channel '11'
        option hwmode '11g'
        option path 'pci0000:00/0000:00:11.0'
        option htmode 'HT20'
        option disabled '0'

so we miss the irq

449

You only need to define the wifi node inside the pci node if you want use the integradted gpio controller of the pcie device... But i´m a fan of defining it anyways if the pcie device isn´t plugable because this will exactly describe the hw.

450

this is missing from ath79, maybe this is not correct in dts ?

	gpio-i2c {
		compatible = "i2c-gpio";
		sda-gpios = <&gpio 1 (GPIO_ACTIVE_HIGH|GPIO_OPEN_DRAIN)>;
		scl-gpios = <&gpio 0 (GPIO_ACTIVE_HIGH|GPIO_OPEN_DRAIN)>;
		#address-cells = <1>;
		#size-cells = <0>;

	};

incorrect kernel on ar71xx is missing this too, earlier on ar71xx I tested by mistake a generic board kernel instead of pb44 personalized one. maybe @hnyman board needs i2c-gpio activated too
and it uses pci not pcie

451

@lucize, This is the dts file with the changes

&mdio0 {
   status = "okay";

   phy0: ethernet-phy@0 {
   	reg = <0>;
   	phy-mode = "rmii";
   };

   phy4: ethernet-phy@4 {
   	reg = <4>;
   	phy-mode = "rmii";
   };
};


&eth0 {
   status = "okay";

   phy-mode = "rmii";
   mtd-mac-address = <&uboot 0xe0000>;
   phy-handle = <&phy0>;

/*	fixed-link {
   	speed = <100>;
   	full-duplex;
   };*/
};

&eth1 {
   status = "okay";

   phy-mode = "rmii";
   mtd-mac-address = <&uboot 0xe0000>;
   phy-handle = <&phy4>;
   mtd-mac-address-increment = <1>;

/*	fixed-link {
   	speed = <100>;
   	full-duplex;
   };*/
};

Here is the dmesg with these changes, lan ports still not working for now

can you try this patch(don't think will help but who knows)?

wget https://github.com/openwrt/openwrt/pull/1146.patch
patch -p1 < 1146.patch

maybe I'll try to ad some OF info to the switch driver, who knows..

456

Thx! I'm ready to test.

I've tried this patch and ported Netgear WNR2000v3. All seems work OK except restarting network take a long time to reconnect. When I change Lan IP and apply the settings, Luci can't get response and I have to reboot the router. So the change recovered.
This is my commit.

Here is dmesg log:

But I have another problem with the file "tiny-netgear.mk"
First time I put the section "define Device/netgear_wnr2000-v3" before "define Device/netgear_wnr612-v2" and rum make. The generated factory image file contains the wrong NETGEAR_BOARD_ID. It is "device:N150R" but not "device:WNR2000V3".
It seems that the varaible NETGEAR_BOARD_ID is repalced by N150R. So I have to place the section "define Device/netgear_wnr2000-v3" to the last of the file. Is it a bug in Makefile or something else? Anybody can help?

This is a know issue on ath79 at the moment...
Restart does work, but a reload will not work.

This does work:
/etc/init.d/network restart

This does not work (luci does only reload):
/etc/init.d/network reload

But only if you change the ip of a interface!

Hi !
Does anyone work on the port for wndr3700v2 ?

If so, I will gladly test it, or maybe someone has a dts file for wndr3700v2.
In the openwt git tree it is only for wndr3800 and unfortunately I do not know what to change in it to be correct for the 3700v2 model.

and @hnyman please test on Your ar7161 devices this dirty patch : https://ptpb.pw/QHmf.patch
With that wifi should work. Proper fix will be submitted in few days.

461

I have also a ar7161 device that is DIR825b1. The dts file is easy to make. It is similar.
If wifi starts working, I will test and send a PR.

I made an ath79 build with that change, but I still see no interrupt assigned for the wifi devices.

Do you have idea how the working wifi definition should look like?

463

There are some gpios involved in enabling wifi, see:
https://git.openwrt.org/?p=openwrt/openwrt.git;a=blob;f=target/linux/ar71xx/files/arch/mips/ath79/mach-wndr3700.c;h=b9132fc363d71027c47e1728215cc0bb571ef560;hb=HEAD#l158
Also some calibration data seems to be necessary, maybe it needs to be added to this file:
https://git.openwrt.org/?p=openwrt/openwrt.git;a=blob;f=target/linux/ath79/base-files/etc/hotplug.d/firmware/10-ath9k-eeprom;h=a687239d44b61bca680d74732f52b94dd8ed8405;hb=HEAD
I'm not experienced in this, maybe @juppin and @lucize can add more input.

BTW proper PCI fix is already in master (that was blazing fast).

Didn't reply directly, look at previous post.
Another thing, probably You'll need this symbol enabled in kernel config CONFIG_ATH79_PCI_ATH9K_FIXUP=y.
