Linux/DP83822H: Unable to ping

Naveen Kumar35

Part Number: DP83822H

Tool/software: Linux

Hi,

We are using DP83822 Phy in our MPC8360 based customized board in MII mode. We are able to see the link active (100Mbps )when connected to PC, but ping is not happening. We have verified all phy configuration registers and all seems fine. We have monitored rx_clk,tx_clk, ,tx, rx and tx_en lines and all seems fine. We are unable to find the issue which is causing ping fail. Please help us in resolving this issue.

Thanks

Hi Naveen,

Please send me the schematic and register dump for register 0x0 to 0x1F, also register 0x467 and 0x468.
Have you confirmed that you are trying to ping the correct IP?
