You can use GPIOs available as select lines to the MUX. CCG2 and later EVKs use Crosspoint Switch for switching between the lines for different configurations of display port (eg: 2 lane or 4 lane).
Please note that there are no EVK or reference designs for CCG6.
Thank you for the response and for verifying my assumption that I can tie one of the GPIO as a select line to the Mux.
My assumption is that the ‘EZ-PD Configuration Utility’ has the ability to set this up, but maybe only on a subset of the GPIO. So which one do I select? Also, what configuration settings do I need to use to select the GPIO?
If my assumption is not correct then I suppose I must use the EZ-PD SDK and modify the code to suit my design. This I was hoping to avoid.
The firmware needs modifications based on the MUX and configurations needed.
Since you are using a MUX in place of a cross point switch. Please modify and replace the respective part of the code with the required functionality.
EZ-PD configuration Utility is used to alter the configuration parameters. You need to add a GPIO and describe the functionality using PSOC creator.
Ok, thanks for the support Yatheesh.
