Hi

Well, both led's are working. When I ping from my host to the target,
I can only see the RX led blink. However, after some time I see
the host's MAC address in the arp table on the target.

When I ping from the target to the host, both RX and TX leds blink.

It seems as if the target only accepts broadcast MAC frames....

Any further idea?

What kind of kernel are you using? 2.2.13? Montavista?

Ruedi

Looks like you are progressing ...

Do not enable DEBUG messages - I believe that they f... things up.


Do you see the RX and TX leds working ?

Cheers,
Nicolas
