Did you use the program written with a previous version of sdk with a new SDK ??
Can you be more specific on which SDK you use currently..
same for me: the issue appeared as soon as I started using dynamic allocation malloc and free library functions in my EZUSB-based program.
Since I cannot imagine C programming w/o dynamic memory allocation i assume some link / compile some missing library or add some options to the compiler I guess. Please help: I am scary to mess up the project
