Hi all,
We are using 88e1111 PHY chip on Stratix II GX PCIe board. The problem is that we are not able to do auto-negotiation. We made auto-neg bit 1 in a regiter on PHY chip. Even we cant make it. Please suggest what should we do more to auto-negtiate the MAC core using that PHY chip on Stratix II GX PCIe board.
Thanks in Advance...

Hi,
The environment is not so clear. The block diagram may assists. I used this Marvell PHY and never see such problem. You'd check all configuration pins, clock, voltages, power to transformer etc.
Also start/restart autonegotiation bit located in register 0. Register 1 services for indication if process complete or not
By the way force link mode is working properly? The traffic is running without losses?
