Is the code that you showed the only thing that you programmed into the chip??
If so then you have left out support for the reset vector and any other initialization that your chip may require. You need to know that many modern MCUs need some initialization code to run to configure things like the oscillator, UART port, Port properties selection. I see nothing like that in the code you say is your program. Also be aware that when you came here with a question you didn't bother to tell us what exact MCU that you are using. There are so so many many variants of the 8051 it would not be possible to give specific advice about things that may be missing from your code. Michael Karas |
