Self-Test Assignments for PL LEDs
STEP 4:
Run the Built-In Self-Test
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 PL GPIO LED is off. The test status LEDs are next to each pushbutton (PB). 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, EEPROM, 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 (SW14, SW15, SW17, and SW18). The pushbuttons can
be pushed in any order. The LEDs are by the pushbuttons.
•
The LED for the test that is waiting for your input blinks.
