[lwip-users] Problems using "chargen" sample code

[Maddala Subrahmanyam]

Hi Haas,

 

Thanks for your quick reply.

I did some debugging myself and found finally the problem is because of missing flag setting.

 

netif->flags  |= NETIF_FLAG_UP;

 

The tap0 driver (/contrib/ports/unix/netif/tapif.c - low_level_init() doesn't bother to set the network interface flag up after it successfully sets the IP. I don't know if it is a bug in the existing code.

 

I set the flag up for the newly created tap0 interface and now the sample code works like  a champ.

 

Thanks a lot for the sample code.
