RE: [lwip-users] Problems with Spartan 3e

[Matthew Yingling]

To poll you just need to call xemacif_input(default_netif);  This calls the
LwIP driver for the Xilinx EMAC.  To ensure you have the right driver,
you'll need to disconnect the Interrupt pin of the EMAC.

Hi Sathya,
Thanks a lot for your reply.
I don't want to use interrupts at this time but also didn't know how to
poll the ethernet. Is there something I have to change in the
"lwipopts.h" to use Polling-Mode?
The echo- and webserver in XAPP663 aren't independent applications?
Maybe this is the problem.
I'll try out the other two examples. These applications use Socket API
and are Interrupt driven, right?
Is there an other example that uses Raw API and Polling Mode?

Mirko
