TMS320DM8147: Ethernet data transfer Issue

Part Number: TMS320DM8147
Other Parts Discussed in Thread: DP83867IR


We are interfacing TI Processor DM8147 with TI Ethernet Phy DP83867IRPAP, RGMII Interface.

We are using CPSW driver, and with default basic configurations, trying to establish communication.

Hardware strap settings for Ethernet Phy is enabling auto-negotiation and MDIX crossover.

When the link partner is forced to 10Mbps, and 1Gbps, link is established, but failing to transfer packets. However, for 100Mbps, even link is not established.

We are able to access the status registers, where the changes made are reflected accordingly.

Please give your suggestions on the same

Thanks and Regards
