Run the Built-In Self-Test
STEP 4:
The BIST consists of a set of pass/fail tests that run sequentially. As each test passes, its corresponding LED glows
green. If a test fails, its corresponding LED is off. The flashing LEDs are next to SW13. For SW13, up is ON or 1.
Note: To pass the PL DIP test, all the switches in SW13 must be up before any of them are moved down. The
LEDs flash faster after you begin the DIP or pushbutton (PB) test.
• The Clock, BRAM, PL-DDR4, PS-DDR4, Flash, and I2C tests run without user input.
• The DIP switch test (SW13) waits for you to move all the DIP switches toward the label ON, and then back.
• The PB test waits for you to push all the pushbuttons. The N, W, S, and E pushbuttons can be pushed in any
order, but push the center button (SW15) last.
• The LED for the test that is waiting for your input slowly flashes on and off.
