PMG1_PD3_SNK_EPR support on CY7113 Dev Kit

requesting 28V EPR does not work

PMG1_PD3_SNK_EPR

We are trying to use CY7113 along with an Apple 140Watt EPR capable adapter and a certified EPR 240watt cable we designed using Hynetek E-Marker 

Cable Setup has been verified to work by using Power-Z tester that is capable of 28V EPR request, so we know all parts of our setup are working correctly 

Now we are attempting to make the 28V PD EPR request using a cypress CYPM1311-48LDXI  on the CY7113 Dev Kit

Issue is that in the documentation it clearly states that there is a few options for PD stack loading and we tried to request EPR using default  PMG1_PD3_SNK_LITE and PMG1_PD3_SNK_LITE and it seems these are not functional 

COMPONENTS=PMG1_PD3_SNK_EPR
COMPONENTS+=FREERTOS

also tried both example codes 

USBPD_Sink_using_FreeRTOS and USBPD_Sink

When Using PMG1_PD3_SNK_LITE we can request legacy SINK Voltages up to 20V but as soon as we load PMG1_PD3_SNK_LITE we can no longer make legacy profile requests nor EPR requests

Please Help

Hi,

EPR is implemented only in USBPD_Sink_CAPSENSE example. https://github.com/Infineon/mtb-example-pmg1-usbpd-sink-capsense

Please refer to Readme of the same example for exact usage of the EPR library and configurations. Let me know if you have any further queries.
