i.MX6 GMAC to GMAC connection

Hi experts,

 

I have a problem of GMAC to GMAC connection between i.MX6 and RTL8364 gigabit switch.

The nets connection are correct and ENET_REF_CLK is connected to 125MHz Oscillator.

In our Android software setting only has AR8031 PHY driver, we don't know how to make i.MX6 work with RTL8364 switch.

We got RTL8634 driver but we don't know how to replace original AR8031 driver in u-boot and Android kernel.

MDIO is workable and can read out registers from RTL8364.

RTL8364 has TX_CLK 125MHz output but i.MX6 doesn't output GTX_CLK.

Could you help us?

Thank you.

 

RGMII connection as below.

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
