adv7625 Rx HPA get low state anyway

Category: Hardware
Product Number: ADV7625

Hello there,

We have a design based on ADV7625, the purpose is to forward the HDMI signal from RxA to TxA, and split the audio signal to SPDIF with AP1. At present, we have tried to modify the I2C register to configure Rx1 like manual set the state of HPA or takes its value based on hpa_auto_int_edid. However, the HPA states of the RxA interface is always act low which causes the signal source to fail to connect normally.

How should I deal with it?
