>>The CYPD3171-24LQXQ_pb supports PD 3.0 specification.
>> CCG3PA in sink charging mode (Power Bank solution) supports BC 1.2 and Apple charging only, it does not support QC or AFC.
>> Ensure that the source supports 12 V to power the sink.
Can you share the source PDOs or the cc logs showing source_caps.
Thanks a lot, I only want to use the sink mode, so I replaced CYPD3171, and I changed to BCR(CYPD3177).
