IMX6Q RGMII Mac to Mac Connect Marvell Switch 88E6176 Port6，How to add driver?

[successansucces]

Below is a full list of our connections .

i.MX6               Switch

--------               ----------

TXD[3:0]---------RXD[3:0]

TX_CTL----------RX_CTL

GTX_CLK-------RX_CLK

RXD[3:0]---------TXD[3:0]

RX_CTL----------TX_CTL

RX_CLK----------GTX_CLK

*ENET_REF_CLK connected to external 125MHz source

Now, Switch can output 125MHz clock and TXD[3:0] have data output to IMX6Q.

But, IMX6Q can't output 125MHz clock and TXD[3:0] can't output data.

How should I modify the driver? Please give me the step.

Thank you very much!

有谁知道的请指点一下啊！万分感谢了！

Dear Successan,

We are designing a product and we have exactly same connection as you. We have connected imx6q MAC to MAC with same Marvell 88E6176 switch.

Did you managed to make it working? If Yes, will you please share your pseudo code you modified in u-boot?

I am implementing my code for our design and your reference will be helpful for us.

Hope to get response from you soon.
