Re: [lwip-users] Recv en socket TCP

[Oscar F]

another thing,i would like reduce the amount of memory, maybe the reason of the problem is that. 
I use TCP coonection with socket, need 8 socket the can yuo say me that define of lwipops.h can i reduce and forgot, for example RAW option?

OK it´s a good idea. the problem is that i don´t know with port the library to AVR32. I you know the people say me please, i will look for this person.

thanks

You could try contacting whoever did the port that you're using and see
if they are willing to offer support.
