Eclipse Integration

I'm trying to run the debug in eclipse with the example 'hello world' program, but am running into issues. Namely, the message "No source available for "0xfffffffe"" is indicating issues. This memory location is where the program counter register says it is. Console dump listed below.

Hi,


Quoted

Starting target CPU...
...Target halted (DBGRQ, PC = 0xFFFFFFFE)

Seems like a reset occurred.
Does the application use local resets or is there any chance that a hard fault was triggered?

Best regards,
Niklas

My entire code right now is this:
------------------------------------------
#include <stdio.h>
int main(void) {
int test = 0;
while(1) test += 1;
return 1;
}
-----------------------------------------

I suspect it's somewhere in the configuration, but don't see anything that stands out. I've attached screen shots of the configuration tabs for the Segger device. I'm using an Atmel ATSAMD11D14AM
