I have a P1010RDB and a custom PCB based on the RDB both with the Vitesse vsc8641xko phy chip using SDKv1.5. I have been unable to obtain a gigabit connection to either board, which is a requirment for us. I have tried connecting directly from the RDB to a laptop with gigabit and through a gigabit switch ,both using cat 6 cable, but the RDB and our PCB will only connect with a 100/Full connection.
Thinking there was a driver issue I looked in U-boot and found support for the vsc8641 in U-boot. I did not find support specifically for the vsc8641 in the kernel, the chip is not listed the vitesse.c file. Since there is a network connection there must be another, possiblely generic, driver controlling the chip?
Is the lack a specific driver the issue? Or is this more of a speed negotiation issue?
Thanks for your ideas! I can provide any info needed I'm just not sure what would be helpful at this point.
