6.3.4 Common Problems and Troubleshooting
If the demo does not function, follow these guidelines to troubleshoot.
1. Ensure that both CCG EVK base boards and the CY4541 CCG4 daughter card are powered by verifying that LED1 (Green)
on all of the boards are ON.
2. Ensure that LED2 (Orange) of CCG EVK base board 1 is blinking continuously. If LED2 is not blinking, CCG4 is not active.
Assert and release the reset button on the CY4541 CCG4 daughter card (SW1).
3. Ensure that the boards are powered before connecting the DisplayPort cables.
4. Ensure that the CY4541 CCG4 daughter card is connected to both the CCG EVK base boards.
5. Ensure that the
“Extended Display” is enabled in the USB host PC.
6. If the PC video is not displayed on the monitor, assert and release the reset button on the CY4541 CCG4 daughter card
(SW1).
