Part Number:DP83867IS
Hello,
Our customer use the DP83867IS, with SGMII.
It occur communication error. The signal of the MDC, MDIO and TD_x_x are correct,
but there is no data at SGMII_SON, SGMII_SOP, SGMII_SIN and SGMII_SIP.
The setting of the customer as below.
Connect their board to PC
PHY address : 3
Using SGMII MAC Interface
Enable Auto Negotiation
PC speed : 1000Mbps , Full-Duplex
They checked the register data dump. The AUTO-NEGOTIATION COMPLETE bit of the BMSR is High,
but the SGMII_AUTONEG_COMPLETE bit is Low.
Does it need the SGMII_AUTONEG_COMPLETE bit High for the correct communication?
I attach the register data dump file. It is the data when the issue occurred.
