Hi All,
We have the DP83867ERGZT in RGMII mode to the MAC.
We are having intermittent issues in loosing packets/pings from link partner to the MAC.
The link partner sends it out (wire shark sees it) but MAC never receives it in uboot or linux
We probed the TXclk & Rx clock @125Mhz.
TX0,1,2,3 toggle.
RXD,1,,2,3 toggle.
Far end loop back-works consistent
Analog Loop back works consistent
When we do pings of 32 bytes size or more we see packets not reaching the MAC.
RXD0 resembles clock
Power sequence /power supply- we are confident but ye to check.
Questions:
1. Is it okay RXD0 to resemble clock?
2. do you know if we have a MII decoder in the market?
3. is there an errata sheet for this phy?
BR,
Bala
