I am currently designing an ethernet driver on a PowerPC 8280. I'm using the evaluation board PQ2FADS-ZU.
To validate the issue of my ethernet frame, I connected with a crossover cable, my evaluation board to a PC with wireshark running. This configuration works. Frames are correctly sent and received on the distant PC. All my frames are displayed on wireshark.
My problem is this.
When I try to connect my evaluation board to a cisco switch (to send frames to multiple PCs), the switch (a Cisco Catalyst 2950) did not not detect the presence of a connection, the LED is off desperately.
So to sumarize, my PC network card can receive my ethernet frames, but my cisco switch can't. I don't know why.
In advance thank you.
PS: The connection is configured for full duplex 100M.
