Linux/DRA72: How to add new phy chip support in VSDK ?

Hi
For linux, check if a generic PHY driver that linux supports can handle the phy
Otherwise you need to specify the compatible phy driver in the device tree definition file

the default settings for the PHY mode is also specified in the device tree file

For instance dra72-evm.dts has
&cpsw_emac0 {
phy_id = <&davinci_mdio>, <3>;
phy_mode = "rgmii"
}

You need to update this as per your platform, to replace rgmii with mii and with the right PHY address mapping

Hi,experts,

Could you give more details about this? such as Pinmux /Phy_id, and so on.

Now in uboot, 

I am trying to figure out what u-boot is telling me

Net:   wait_for_user_access Timeout
wait_for_user_access Timeout
wait_for_user_access Timeout
wait_for_user_access Timeout
wait_for_user_access Timeout
wait_for_user_access Timeout

a lot of "wait_for_user_access Timeout"

wait_for_user_access Timeout
PHY reset timed out

Best Regards,
