[FAQ0201278]AW35615 MTK平台驱动中如何证明PD握手成功？ | FAQ

A：PD握手成功或者升压成功，PE状态机会置为peSinkReady或peSourceReady，进入如下代码位置，并上报给平台当前处于FIX通信还是PPS通信。

if (chip->port.PolicyState == peSinkReady &&

chip->port.PolicyHasContract == AW_TRUE) {

if (!chip->port.pd_state) {

chip->port.pd_state = AW_TRUE;

chip->tcpc->pd_port.data_role = PD_ROLE_UFP;

chip->tcpc->pd_port.power_role = PD_ROLE_SINK;

if (chip->port.src_support_pps) //支持PPS

tcpci_notify_pd_state(chip->tcpc, PD_CONNECT_PE_READY_SNK_APDO);

else //支持FIX

tcpci_notify_pd_state(chip->tcpc, PD_CONNECT_PE_READY_SNK_PD30);

}

AW_LOG("aw35615 req_obj=0x%x, sel_src_caps=0x%x\n",

chip->port.USBPDContract.FVRDO.ObjectPosition,

chip->port.SrcCapsReceived[

chip->port.USBPDContract.FVRDO.ObjectPosition - 1].object);

}
