Different behaviour in debugging and stand-alone

Ok, I see, my desciption is poor ;-)

I use for debugging the Cygnal C8051F Driver, newest version.

This is my code:

main()
{
  if ( RSTSRC == 0x08 )
  {
    WDTErrorFlag = 1;
    Initialize();
    ShowError( E_WD );
    Wait1Min();
    WDTErrorFlag = 0;
    RSTSRC = 0x10;
  }
  else
  {
    WDTErrorFlag = 0;
    DoSomething();
  }
}

    DoSomething();
  }
}

I don't know that particular chip. But this:

	RSTSRC == 0x08

	(RSTSRC & 0x08) == 0x08

There is nothing in your code that prevents the program from exiting the main function.

Perhaps that is the cause of the second "reset".

Typically, the main C function for embedded programs is implemented as follows:

void main (void)
{
whilw (1)
  {
  /*** do something ***/
  }
}

Hello!

The while(1)-loop is within the else-part.
The problem was the test indeed! Thanks very much!!
