Hi Team,
I got a problem when use TPS65987D on a new project, the problem is PD can't work, I measured the SPI wafeworm when power on, it likely loaded, but the GPIO0,1,2,3 and CC1/CC2 status is abnormal, GPIO status is always high impedance, and CC1/CC2 is always low, and attachment is schematic and configuration file, please help to check which cause the problem.
SPI SDO and CLK waveform when power on:
And if I power on the unit on TYPE-C hub side, the GPIO0,1,2,3 and CC1/CC2 status is become OK, and TYPE-C sink/source function OK, if power on it on DC side, it is abnormal.
below picture power path is OK:
