C51 Some problems

Good days!
Sorry.
I work with Keil .Vision3 V3.30a.
Have some C8051F060 devices.
When processing my programms under Debuger control don't have any problems.
But after device FLASH programming and abort Debug Session I get some problem. When read microprocessor input ports I get not correct information about input signals.
What is it?

Thank You!

    Do you really mean the debugger - ie, the code running in your target?

    Or do you mean the Simulator - ie, the code running on your PC?

    "When read microprocessor input ports I get not correct information about input signals"

    In what way are they "not correct"?
    You need to clearly understand the problem before you can solve it!

    Similarly, you need to clearly explain the full situation before anyone else will be able to help you:

    - What is the system supposed to do?

    - What is actually happening (in detail)?

    - What have you done to try to explain the difference?
