How to set a phy loopback mode in EVMK2h

I want to test ethrenet phy loopback in EVMK2H

I read a 88E1111 Datasheet, I saw that 88E1111 has Loopback mode.

Would I set a phy loopback mode in 88E1111 and I test a phy loopback in EVMK2H??

My board version is Rev 4.0

Regards.

Dear Shin,
Yes, you can do that.
Currently we don't have loopback test code for K2H PHY.
You may have create your own code for that.

You can find the SGMII loopback sequence in Keystone Gigbit Ethernet user guide.

Hi Titus.

Thanks for your reply. I understand how to SGMII loopback. but I need to use a 88E1111 phy chips using MDIO controlling. NOT SGMII and SERDES. SGMII and SERDES are including DSP SOC.

I hope to test connection between DSP SOC and 88E1111 Phy Chips.

Regards.

Shin.
