Thank you Andy. I think it is really the reset vector, but I cannot change it until Peter gave me the solution.
Thank you too Peter. It really works. By the way, I dont know one C compiler easy to use in the command line. If there is, please let me know and I will get it, because I prefer it as IDE. The advantage of IDE system, i think, is the debbuger and its friendly user interface, nothing more.
Regards,
Luis
