Hello,

I am using:
eclipse-platform-3.2-win32
btnut_system_1.8
and WinAVR-20070525

I am using c++ for btnodev3.

When i burn the .hex file i get the following warning:
[LPM] Device is not responding correctly
All four LED's of BTNODE hardware are blinking continously, but when i connect it using hyperterminal there is no output, even i have certain printf code in my main.

My main file look like(i simply used the cppdemo, how ever even cppdemo .hex file is not working on BTNODE):

#include "Main.h"
// Trivial C++ Demo for NutOS.

I want to make the C++ code run on BTNODEv3. Can any one guide me how to make it work???
