Hi, is there someone having a driver for the Teridian 78Q2133 ethernet PHY? I adapted the example out of the AT91SAM9260 software package from Atmel to wotk with this PHY, but the auto negotiation always fails, resulting in a time out.
Thanks for your help.
I almost don't know anything about Networking.
But I know that Autonegotiation is the behavior between two devices. Maybe the problem is not on the Teridian 78Q2133? Did you check the device at another side?
Incompatible? en.wikipedia.org/.../Autonegotiation
The first version of the autonegotiation specification, IEEE 802.3u, was open to different interpretations. Although most manufacturers implemented this standard in one way, some others, including network giant Cisco, implemented it in a different way. Autonegotiation between devices that implemented it differently failed. This led many network administrators to not depend on autonegotiation and instead manually set the speed and duplex mode of each network interface card. Even Cisco recommended its customers not to use autonegotiation.
When using WinCE which is available for this board, the ethernet connection works fine. Thus it must be a configuration fault...
