I'm guessing the program is too big for my target board. Can I get pointers to changing options in the LWIP build to remove the DCHP and TCP. I'm only going to use UDP for this project.

In the ReadMe.txt file,

<div class='quotetop'>QUOTE </div>

--- Quote Start ---

- lwipopts.h: Default values and features for building the LWIP stack.

This set will work for most applications. Care must be taken to fully

understand the implications of changing any default value. Refer to

/lwip-0.7.1/src/include/lwip/opt.h for other features or values that can

have a default in lwipopts.h.[/b]

There are also options that you can try at the HAL level (on the system library properties page) that will reduce the memory footprint.

I've not tried any of this, myself, but it seems like a reasonable place to start.

Cheers,
