Hi Simon,
I think I've partially fixed the issue. While going through the default config
I noticed that the TCPIP thread's default priority is set to 8. Which was lower
than my threads prio - 5.
After changing it to 2, it's able to find the interface (et0) with all
the right settings.
Now another problem has cropped up! :) Sorry.
My app's actually a DHCP server. So it receives DHCP packets with 0.0.0.0
as the src IP. However, the stack is dropping them with the following message:
ip_input: iphdr->dest 0xffffffff netif->ip_addr 0x101010b (0xffffff,
0x1010b, 0xff000000)
ip_input: packet accepted on interface et
ip_input: packet source is not valid.
I've enabled the following in my config:
* Support broadcast filter
* Receive support
Is anything else needed?
Just one more thing:
While tracing the path from cyg_lwip_sequential_init() to see what
all happens, I saw that
we end up calling lwip_init() twice!
Once in cyg_lwip_sequential_init() and then again in tcpip_init().
Why do we do it twice? The only function called between these 2 calls is
cyg_semaphore_init().
I think we can remove one of these. Or am I missing something?
Thanks,
-mandeep
