IMX8DX device tree, Second Ethernet configuration

xMark94 · November 9, 2023, 4:03pm

Hi, we have some troubles defining the second ethernet port using device tree overlays.

We have noticed, using the Toradex Pinout designer that the MDIO and MDC pins are shared for the two ethernet ports.
Defining the ethphy2 in the fec1 as for the ethphy1 we were able to make the second eth port work but we are not able to set Phy parameters like as “micrel,led-mode” or “max-speed”.
It seems like as the second phy is ignoring those parameters.
We defined the fec2 in this way in our overlay dts:

/* Colibri FastEthernet */
&fec1 {
	pinctrl-names = "default", "sleep";
	pinctrl-0 = <&pinctrl_fec1>;
	pinctrl-1 = <&pinctrl_fec1_sleep>;
	phy-mode = "rmii";
	phy-handle = <&ethphy0>;
	fsl,magic-packet;
	fsl,wakeup_irq = <0>;
	status = "okay";
	mdio {
		#address-cells = <1>;
		#size-cells = <0>;
	
		ethphy0: ethernet-phy@2 {	
			compatible = "ethernet-phy-ieee802.3-c22";
			max-speed = <100>;
                        micrel,led-mode = <1>;
			reg = <2>;
		};

		ethphy1: ethernet-phy@1 {
			compatible = "ethernet-phy-ieee802.3-c22";
			max-speed = <100>;
			micrel,led-mode = <1>;
			reg = <1>;
		};
	};
};

/* Colibri FastEthernet 2 ETH2 */
&fec2 {
	pinctrl-names = "default";
	pinctrl-0 = <&pinctrl_fec2>;
	phy-mode = "rmii";
	phy-handle = <&ethphy1>;
	fsl,magic-packet;
	fsl,mii-exclusive;
	status = "okay";
};

&iomuxc {

The output of the “dmesg” command is the following:

What are we doing wrong?
Thanks in advance for the support.

Dear @xMark94,

Sorry for the delay in answering!
Could you please specify which kernel version you are on? Then I could check how the ethernet is being configured for that version.

xMark94 · November 17, 2023, 10:41am

Hi Rudhi
My Kernel is the following:

uname -a:
Linux colibri-imx8x-07266862 5.4.193-rt74-5.7.2-devel+git.b60d3160fd04 #1 SMP PREEMPT_RT Fri Dec 23

rudhi.tx · November 21, 2023, 3:02pm

Hello @xMark94,

Looking at your device tree snippet, I think you have made the right modifications. Also, from the dmesg logs it looks like the MDIO communication works and the PHY is also recognized. We can also see that both the ethernet interfaces are auto-negotiated to 100 mbps speed. So may I ask what issue you are facing here?

xMark94 · November 21, 2023, 3:38pm

Hello @rudhi.tx,
The micrel led mode is not correctly interpreted for eth2.
The leds are blinking like as in mode “0”, instead for eth1 they are working correctly.
Also, if I try to change the max-speed for eth2 and set it to “max-speed = <10>”, the value is ignored too, and setted instead to 100.

It seems like those parameters are completely ignored for the second ethernet interface.

rudhi.tx · December 6, 2023, 1:11pm

Hello @xMark94,

The configuration looks good to us. Could you please send us the full dmesg log?
You could also use phytool to access the phy registers directly to see if they have the correct values. You can check it as follows:
phytool read eth1/1/0x1e
Here the register value should be 1.

I can send you the phytool cross-compiled for arm64 so you don’t have to compile it again.
phytool (1.3 MB)

I tried with the phytool you gave me, here the results:

The register 2 is associated to the phy of the first ethernet port, and register 1 is associated with the phy of the second ethernet port.
We can see that we are able to set the correct led mode through the “phytool write” command but the driver seems not to be able to configure it at the start.

We obtain the same result also using “ifconfig eth1 down” “ifconfig eth1 up” to reconfigure the ethernet port.

Hi @xMark94

I’m not sure if I got it correctly, if you do an:

ifconfig eth1 down
ifconfig eth1 up

Then the led-mode is set correctly? If so, I assume that the phy is already up when the Linux driver loads and therefore it will not do a reconfiguration of it. Do you have a reset pin that you could use to reset the PHY via GPIO? Most likely if you keep it in reset and just release it by assigning a reset-gpio could help:

		ethphy1: ethernet-phy@1 {
			compatible = "ethernet-phy-ieee802.3-c22";
			max-speed = <100>;
			micrel,led-mode = <1>;
			reset-gpios = <&gpio 9 GPIO_ACTIVE_LOW>;
			reg = <1>;
		};

Regards,
Stefan
