Tool/software:

Hi~ TI teams：

As the title suggests, I hope to activate the network port function. May I ask how to adapt the RTL8211F chip on the device tree? Could you provide any relevant tutorials or configuration instructions?

PS: The network card has been recognized now, but it cannot be used online.

Thank you!

RTL8211F is a PHY chip from Realtek. We do not test Linux drivers for that device with our SoCs. It does seem to have Linux drivers. Google search for "RTL8211F linux device tree" yields some guidance. Have you contacted Realtek for pointers to how to configure device tree for their PHY?

So, could you please specify which brands of PHY chips you have adapted to? Are there any referenceable instructions or examples available?

Hello Jinzhi,

The PHY chips that we have tested with our SoCs and have specific examples of device trees are those used on our TI EVMs. It looks like you are using AM625 SoC, the TI EVM for that is SK-AM62B-P1 which uses DP83867 Ethernet PHYs.

Have you taken a look at How to Integrate Linux Driver Into Your System, section "Linux Device Tree"?
