RE: [ECOS] Ethernet problem

["Nejat Tek" <tek at delcomsys dot com>]

What I can suggest is that you start with finding a "packet sniffer",
for example "tcpdump" for your PC. With "tcpdump", you may verify that

1) Packets are really being transmitted out from your board ( The
communication starts with two arp requests that has to come out
of your board in ping_test )

2) What the outside world sees your hw_address is. ( tcpdump shows
the content of the packets, and arp request packet has the hw_addr
info in it ).

It should be set on the hardware interface, the code looks like :
    memcpy((void *)&fec->addr[0], &enaddr[0], sizeof(enaddr)); 

The hardware address advertised in the debug printout comes 
from "build_bootp_record" function in 
"... packages/net/tcpip/current/src/lib/network_support.c".
That neither shows the actual hw_addr nor does it effect the
operation of the ethernet ....

Good luck,
