Hey Everyone,

I have a project where I want to use the LCPopen "LWIP+FreeRTOS TCP Echo" example to start off. Since I am using gcc I wrote my own Makefile for it.

The problem I am having is, that it will throw a Hard Fault, when accessing the net_if struct. I guess this has something to do with alignment, but I cant fix it.

I'll try to supply all info to get to the root of this:

Hard Fault happens here:<span class="inline inline-left"><img class="image image-preview " src="http://www.lpcware.com/system/files/images/hardflt.preview.jpg" border="0" alt="" title="" width="640" height="257" /></span>

The project is the LPCopen LPC17XX_40XX freeRTOS+LWIP example running on a LPC1778

Compliler is CodeSourcery GCC 4.5.2


I hope this is enough to solve this. Thanks in advance
