Unable to select SRC PDO

RJain.1 · ‎2025-03-30

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.

I appreciate any help you can provide.

@FBL , Can you please check

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.
