Thank you for your answer, Valter.
I'm using a JTAG hardware debugger (RAVEN + Intel compiler EXDI
driver) and I'm not using KITL, for now.
So, BSP_NOSHAREETH = 1
I think that some registry settings are OK, because :
- If I enable DHCP client, DHCP packets are sent to DHCP server and
packets from DHCP are received and decoded correctly. After this the
board send some ARP packets for verifying if IP address received is
valid.
- If I disable DHCP client, ARP packets are sent immediately.
I see also WINS packets in output, but without answer, so I'm
investigating about them.
But after these operations, the board receive for example ICMP packets
but doesn't work.
This is my first job with WIndowsCE and I think I have a lot to learn
....
Any other suggestion is good for me.
