Hi guys,
I'm trying to port port lwIP to a ARM Cortex M3 NXP LPC1768.
I'm using following Example:
http://www.coocox.com/EXAMPLE/NXP_LPC1766_ARMCC.htm
If I want to ping the device, ARP requests of the host computer are
coming in, but the device doesn't reply them.
I could isolate the problem to the function update_arp_entry() where the
reply should be started.
There is a loop, where the queued packets should be sent: while
(arp_table[i].q != NULL).
In my case arp_table[0] gets initialized but arp_table[0].q is always NULL.
For this reason I don't get an ARP reply.
Can anyone help me for my problem?
Thanks in advance!
Best regards from Austria
Robert
