I am trying to use CCG3PA (CYPD3175) with DisplayPort functionality. I have modified the profile in EZ-PD Configuration Utility to have the CYPD3175 to be a power source and a data role swap occurs so that the data port is UFP.
I then offer the SVID of 0xFF01 for DisplayPort. The sink will then sent an Enter Mode Request and the source will reply with a NAK. What modifications to the FW do I need to make in order to send an ACK instead?
I am attempting to use CYPD3175 with DP alternate mode UFP enabled. Is this mode supported with the correct firmware modifications?
If so, please help me to understand how to achieve this.
As you can see in the image, the DFP sends an enter mode request that is followed with a NAK by the CYPD3175.
