Hi guys,
Just wanted to share how I got it working because this forum helped me to figure out the problem.
Linux version 5.4.142
dtb
&fec1 {
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_enet1>;
phy-mode = "rmii";
phy-reset-gpios = <&gpio1 28 GPIO_ACTIVE_LOW>;/*my reset line*/
fixed-link = <0 1 100 0 0>;
phy-supply = <®_vref_3v3>;
status = "okay";
};
Outputs for 2184800 FEC1
The KSZ8775-5 has the following configuration:
Since it is a switch, you will only see one eth interface in my case eth1:
I hope this helps.
Hi everyone
I am using ksz8895 and spi .My connection is as below.
Should I have to use dsa drivers.Is my dts file correct?

Hi pavansingpatil，
I use the RMII and spi mode, the manual says:
MAC/PHY mode in RMII is different than MAC/PHY mode in MII. There is no strap pin and register configuration request
in RMI. Follow the signals connection in Table 3-11.
Hi pavansingpatil，
Find this directory with the following information
Can you give me some advice?thanks
