Hi Team,
My customer is using DP83869HM RGMII to Copper.
It is my understanding that Auto Negotiation can be turned off for 1000Base-T communication and fixed 1000Mbps/full duplex.
My customer will not link up if Auto Negotiation is turned off and 1000Mbps/full duplex fixed communication is used for the other side.
Of course, the opposing device is also set to 1000Mbps/full duplex fixed mode.
Is this behavior correct?
What is your technique for doing this with 1000 Mbps/full duplex fixed communications?
The following did not communicate.
Write 0x0140 to register 0h // BMCR
Write 0x0200 to register 9h // GEN_CFG1 Advertise 1000Base-T Full Duplex ability
Write 0x5008 to register 10h // PHY_CONTROL Manual MDI configuration
Best Regards,
Kenji
