1.3.1. Auto Start Design Demonstration on MDN-B2 Board

To demonstrate the design example on the MDN-B2 demo board, follow these steps:

  1. Ensure that VCCIO voltages on both banks are set to 2.5V (jumpers on JP9 and JP7 on the demo board are set to 2.5V).
  2. Turn on the power to the demo board (using slide switch SW1) and download the design on to the MAX II device through the JP5 JTAG header and a conventional programming cable such as the ByteBlaster™ II or USB-Blaster™.
  3. Keep SW4 on the board pressed as you begin the programming process.
  4. Turn off power to the board and remove the JTAG connector after programming.
  5. Turn on the power to the demo board. Using a voltmeter between TP3 and GND on the demo board, observe VCCINT being powered down and powered up cyclically.
  6. Repeat observation for VCCIO (between TP1 and GND on demo board). Also observe the 4 LEDs (D2, D3, D5, and D6) shift their position each time the power to the device is restored.
  7. Each time the LED blinks, its position is based upon the previous LED position that blinked and in accordance to the LED Mapping table.
