Other Parts Discussed in Thread: DP83869, AM5748, SYSBIOS
Tool/software:
DP83869 is connected to AM5748 SOC through RGMII0. DP83869 is connected to PC through Ethernet cable and auto negotiation is enabled on the PC.
If auto negotiation is enabled on DP83869 PHY, link is up, and data transfer is successful. When DP83869 Ethernet PHY is configured in manual mode link is not up.
We have tried it on Linux and Sysbios, and same observations are seen in both the cases.
