Hello, I have started using 50c81f120 with KEIL C51 compiler. In main program I have some initialization and infinite loop after that( while(1) {} ). When I'm debugging , program enters initialisation, than goes to main infinite loop, a after that goes AGAIN TO INITIALISATION as if it left from inifinite loop and started main() from the begining ??? I don't understand what is the problem, is the stack initializatiom wrong? Is it about the startup automaticly generated asm file (I've chosen not to add that generated file to project, in the beggining). Best regards, Branislava
