Hi,

I am using a custom board based on STM32G4. I have successfully generated SINK code using cubemx and testing it using UCPDcube monitor. Explicit contract has done correctly but unable to select a source PDO.

 

PFA, trace, and screenshot.

Hi @RJain.1 

Did you check the demo provided here.

It appears that the issue lies in the implementation of the USBPD_DPM_SNK_EvaluateCapabilities()function. This function is crucial for selecting the appropriate Source PDO.
