I try to implement lan9303 switch with stm32mp1.

My current achievement is working only one channel

My working dts is

&ethernet0{
	pinctrl-names = "default", "sleep";
	pinctrl-0 = <&eth1_pins_mx>;
	pinctrl-1 = <&eth1_sleep_pins_mx>;
	status = "okay";
	phy-mode = "rmii";
	max-speed = <100>;
	phy-handle = <&switch>;
	nvmem-cells = <&ethernet_mac_address>;
	nvmem-cell-names = "mac-address";
	st,eth-ref-clk-sel;
	clock-names = "stmmaceth",
		"eth-ck",
		"mac-clk-tx",
		"mac-clk-rx",
		"ethstp";
	clocks = <&rcc ETHMAC>,
		<&rcc ETHCK_K>,
		<&rcc ETHTX>,
		<&rcc ETHRX>,
		<&rcc ETHSTP>;
 
	mdio0 {
		#address-cells = <1>;
		#size-cells = <0>;
		compatible = "snps,dwmac-mdio";
		switch: switch-phy@0 {
			compatible = "ethernet-phy-id0007.C0D1","ethernet-phy-ieee802.3-c22";
			/*compatible = "smsc,lan9303-mdio";*/
			reg = <0>;
			clocks = <&rcc ETHCK_K>;
			clock-names = "rmii-ref";
			reset-gpios = <&gpioa 4 GPIO_ACTIVE_LOW>;
			reset-duration = <100>;
			interrupt-parent = <&gpiog>;
			interrupts = <12 IRQ_TYPE_EDGE_FALLING>; /* ETH_MDINT# */
			ports {
					#address-cells = <1>;
					#size-cells = <0>;
 
					port@0 {
						reg = <0>;
						label = "cpu";
						ethernet = <&ethernet0>;
					};
 
					port@1 { /* external port 1 */
						reg = <1>;
						label = "lan1";
					};
 
					port@2 { /* external port 2 */
						reg = <2>;
						label = "lan2";
					};
				};
		};
	};
};

but works only one channel

DSA switch works. For my purpose, I don't need to add a LAN9303 driver. Just LAN911x is sufficient enough. Finally, I understand that this switch works like a daisy chain connection. The conclusion is

&ethernet0{
 
	pinctrl-names = "default", "sleep";
 
	pinctrl-0 = <&eth1_pins_mx>;
 
	pinctrl-1 = <&eth1_sleep_pins_mx>;
 
	status = "okay";
 
	phy-mode = "rmii";
 
	max-speed = <100>;
 
	phy-handle = <&phy0>;
 
	st,eth-ref-clk-sel;
 
	clock-names = "stmmaceth",
 
		"eth-ck",
 
		"mac-clk-tx",
 
		"mac-clk-rx",
 
		"ethstp";
 
	clocks = <&rcc ETHMAC>,
 
		<&rcc ETHCK_K>,
 
		<&rcc ETHTX>,
 
		<&rcc ETHRX>,
 
		<&rcc ETHSTP>;
 
 
 
	mdio0 {
 
		compatible = "snps,dwmac-mdio";
 
		#address-cells = <1>;
 
		#size-cells = <0>;
 
		phy0: phy@0{
 
			compatible = "ethernet-phy-id0007.C0D1";
 
			reg = <0>;
 
			reset-gpios = <&gpioa 4 GPIO_ACTIVE_LOW>;	
 
			interrupt-parent = <&gpiog>;
 
			interrupts = <12 IRQ_TYPE_EDGE_FALLING>; /* ETH_MDINT# */
 
			reset-delay-us = <10000>;
 
			post-reset-delay-us = <1000>;
 
			clocks = <&rcc ETHCK_K>;
 
			clock-names = "rmii-ref";
 
		};
 
	};
 
};

In rootfs, I just see eth0, which works in DHCP mode. The first LAN I connect to the router and the others to a laptop, for instance. So I'm able to address the board from any devices in the system. Don't connect both LAN1 and LAN2 to the same router.

The part

switch: switch@0 {
			compatible = "smsc,lan9303-mdio";
			#address-cells = <1>;
			#size-cells = <0>;
			dsa,member = <0 0>;
			reg = <0>;
			clocks = <&rcc ETHCK_K>;
			clock-names = "rmii-ref";
			ports {
				#address-cells = <1>;
				#size-cells = <0>;
				port@0 {
					reg = <0>;
					label = "cpu";
					ethernet = <&ethernet0>;
				};
				port@1 { /* external port 1 */
					reg = <1>;
					label = "lan1";
				};
				port@2 { /* external port 2 */
					reg = <2>;
					label = "lan2";
				};
			};
		};

It is only needed when you want to filter some packets, make some bridges etc.

That is all. I think this thread/topic can be closed.

Thanks a lot

Hi MWoło.2 (Community Member)

What about the configuration mentioned in this post, it seems both LAN ports are detected using the LAN9303

&mdio0 {

reset-gpios = <&gpioa 4 GPIO_ACTIVE_LOW>;

reset-delay-us = <10000>;

post-reset-delay-us = <1000>;

phy0: ethernet-phy@0 {

compatible = "ethernet-phy-id0022.1622";

reg = <0>;

};

The lan9303 acts as a switch and I am able to use both LAN-Ports .

Hi Olivier

I modified DTS to look as follow

&ethernet0{
	pinctrl-names = "default", "sleep";
	pinctrl-0 = <&eth1_pins_mx>;
	pinctrl-1 = <&eth1_sleep_pins_mx>;
	status = "okay";
	phy-mode = "rmii";
	max-speed = <100>;
	phy-handle = <&phy0>;
	nvmem-cells = <&ethernet_mac_address>;
	nvmem-cell-names = "mac-address";
	st,eth-ref-clk-sel;
	clock-names = "stmmaceth",
		"eth-ck",
		"mac-clk-tx",
		"mac-clk-rx",
		"ethstp";
	clocks = <&rcc ETHMAC>,
		<&rcc ETHCK_K>,
		<&rcc ETHTX>,
		<&rcc ETHRX>,
		<&rcc ETHSTP>;
 
	mdio0{
				reset-gpios = <&gpioa 4 GPIO_ACTIVE_LOW>;
				reset-delay-us = <10000>;
				post-reset-delay-us = <1000>;
				interrupt-parent = <&gpioe>;
				interrupts = <12 IRQ_TYPE_EDGE_FALLING>; /* ETH_MDINT# */
				compatible = "snps,dwmac-mdio";
		phy0: ethernet-phy@0 {
			compatible = "ethernet-phy-id0022.1622";
			reg = <0>;
			clocks = <&rcc ETHCK_K>;
			clock-names = "rmii-ref";
		};
	};
};

and from boot I received

and of course not working.

I also installed net-tools

and typing

mii-tool -vv eth0

I receive something

So I'm not able to read PHY ID.

From the documentation, I read that ID is 0007.C0D1. This ID is identical to LAN911x.

I have a strange feeling that I configured everything good and a problem is related to configuration DSA(switch) into systemd.

My current boot log looks

The eth0 is combined somehow with VLAN. Unfortunately, I haven't enough knowledge of how to do this.

Can someone give me some links to, manual on how to do this in systems, not in busybox.

Thanks

Hi MWoło.2 (Community Member)

Just one remark. Is it specific to the LAN9303 to redefine in the mdio node:

clocks = <&rcc ETHCK_K>;

clock-names = "rmii-ref";

Unfortunately, I have no idea what this VLAN means. I read that LAN9303 do not support filtering but how to disable or work around this. guess that for this reason, I have not received an IP address.

The part

			#address-cells = <1>;
			#size-cells = <0>;
			dsa,member = <0 0>;
			reg = <0>;

			ports {

				#size-cells = <0>;
				port@0 {
					reg = <0>;
					label = "cpu";
					ethernet = <&ethernet0>;
				};
				port@1 { /* external port 1 */
					reg = <1>;
					label = "lan1";
				};
				port@2 { /* external port 2 */
					reg = <2>;
					label = "lan2";
				};
			};
		};

It is only needed when you want to filter some packets, make some bridges etc.

That is all. I think this thread/topic can be closed.

Thanks a lot
