Dear All,I'm trying to integrate USB PD DRP into my code.The DRP does not seems to work. I traced the port interrupts down to the PORTx_IRQHandler and here are the results (USB_PD_Int = Status Register, the time is in ms from the start of the FW):Tim...

Dear Guenael,I work with my own PCB with relatively complicated USB connection, so I'm not sure that You will be able to replicate FW behavior without my hardware. Anyway, I can provide You the project if You would like but please give me the private...
