Test the operation of the ports of your Development board as follows. Write and compile a program to toggle all the bits of PORTA, and PORTB continuously by sending 55H and AAH to these ports.  The PORTA and PORTB pins are connected to the LED of the Board.  Use   your board to watch the bits of the ports toggle on and off. Make sure that the time delay in between the "on" and "off" states is long enough that you can observe each state clearly. .
