6.2.3 Common Problems and Troubleshooting
If the demo does not function, follow these guidelines to troubleshoot:
1. Ensure that both the CCG EVK base boards and the CY4541 CCG4 daughter card are powered by verifying that LED1
(Green) on both the CCG EVK base boards and CY4541 CCG4 daughter card are ON.
2. Ensure that LED2 (Orange) on 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 CY4541 CCG4 daughter card is connected to both CCG EVK base boards.
4. If there is no voltage at jumper J7 (in the Dead Battery Charging demo), ensure that the connected USB Type-C power
adapter supports a 14-V to 20-V power profile.
6.3 DisplayPort Demo
The DisplayPort Alternate Mode demo is an end-to-end demo that demonstrates the following:
▪
Type-C alternate mode support for display: Delivers the DisplayPort video from the host (in this case, a PC) to a display
monitor.
▪
Dual Type-C alternate mode support for display: Delivers the DisplayPort video from the host (in this case, a PC) to
display monitors connected to both Type-C port 1 and Type-C port 2.
6.3.1 Boards, Cables, and Accessories
The following items are needed to perform this demo:
▪
One DisplayPort video source (for example, a PC) with a DisplayPort output connector and DisplayPort Splitter board
(not provided with the kit) or two DisplayPort video sources (two PCs with DisplayPort outputs or one PC with two
DisplayPort outputs)
▪
Two DisplayPort monitors
▪
CY4541 EZ-PD CCG4 EVK (CCG EVK base board + CY4541 CCG4 daughter card, refer to
for more information)
▪
A DisplayPort cable that connects the CY4541 EZ-PD CCG4 EVK to the PC. If the PC has a Mini DisplayPort plug, use
the Mini DisplayPort to DisplayPort cable (DisplayPort cables are not provided with the kit. See
▪
Type-C to DisplayPort, Type-C to HDMI, Type-C to VGA or Type-C to DVI dongle (not provided with the kit. See
6.3.2 Running the Single DisplayPort Demo
1. Use the default jumper settings shown in
to configure the CY4541 EZ-PD CCG4 EVK.
2. Connection details:
▪
Remove wires from the power output header (J7) on CCG EVK base board 1 and CCG EVK base board 2. Connect
wires between the power input headers (J12) of both the CCG EVK base boards as shown in
. Note that this is
the same setup as used in the DRP and SuperSpeed USB demo shown in
▪
Connect the DC power adapter (provided with the kit) to the DC power jack (J1) of either of the CCG EVK base boards.
LED1 (Green) on the CY4541 CCG4 daughter card, and both the CCG EVK base boards glow to indicate that the board
is powered. Also, LED2 (Orange) on the CCG EVK base board 1 blinks continuously to indicate that CCG4 is powered
and active.
