Hi, We have one more query regarding A31's MIPI CSI interface.
In datasheet, GPIO PE16 pin is mentioned as MCSI-MCLK i.e. Master clock for MIPI CSI. There is no description about this clock. Is this clock input for MIPI interface? Is it absolutely necessary for functioning of MIPI CSI module? If yes, what should be it's value? Are there any constraints like it should be generated from CMOS sensor i.e synchronous to MIPI input etc.? In HummingBird board, we see that this clock is routed to CMOS sensor's connector. So we cannot make out about how to feed clock to this pin. On our HW, this pin is left floating. Can this be reason for MIPI CSI interface not functioning? We checked in linux code also but didn't find any reference to this clock in clock framework. But if we see config pin of this PE16 IO, it is configured for MIPI CSI clock. Please let us know if you have any clues/information. Thank you in advance.
