DP83822I: The Ethernet port cannot communicate

Hi Haojie,

Can you please explain more about your issue? Explain your application? and what are the issues being noticed?

The previous thread shared here is about the Eye waveform correction.

Rahul

From time to time, the LED of the network port does not light up, and the ping of the network port fails (the handshake with the computer network port fails)ECG12S1-PHY_20230206v2.pdf

What Link partner is the device connected to?

Can you please share a register dump of DP83822 when the LED on the network port is up and without it?

Thanks,
Rahul
