Hi ,
(1) Can I achieve this without using PR_SWAP and DR_SWAP?Is there a reference example?
>> Yes, you can.
The relates API is :
/**
* @brief Change the PD port configuration at runtime.
*
* This function allows changing the PD port configuration parameters like port
* role, default port role, DRP toggle enable and Try.Src enable at runtime.
* These changes are only allowed while the corresponding PD port is disabled.
*
* @param port USB-PD port to be configured.
* @param role New port role selection (0 = Sink, 1 = Source, 2 = Dual Role).
* @param dflt_role New default port role selection (0 = Sink, 1 = Source).
* @param toggle_en New value for DRP toggle enable flag.
* @param try_src_snk_en New value for Try.SRC/ TRY.SNK enable flag( 0 =
* Both Try.SRC and TRY.SNK are disabled, 1 = Try.SRC is enabled,
* 2 = TRY.SNK is enabled).
* @return CCG_STAT_SUCCESS if operation is successful, CCG_STAT_BAD_PARAM
* if port index is not correct or other parameters are not correct,
* CCG_STAT_FAILURE if port is not disabled.
*/
ccg_status_t dpm_update_port_config(uint8_t port, uint8_t role, uint8_t dflt_role,
uint8_t toggle_en, uint8_t try_src_snk_en);
(2) In this Code example(CYPD4236-40LQXI_dock), the default is UFP/Power Sink.How to change the preset to DFP/ Power Source?
>> You can change the configuration via EZ-PD configuration Utility. And set the port role as attached file.
