Part Number: DS90UB953-Q1

Dear Sir, 

My image sensor is connected with DS90UB953 by a tiny B2B connector, sometimes my HOST cannot recieve image video ,even if the image sensor is  initalized no error. I have to reinstall image sensor board again.

So, is it possible to get the connection status by reading UB953 CSI registers?  for example, sensor  mipi clock or dala  lane is not detected by CSI RX block of UB953?

Best,

    Hello,

    In reg0x5C-0x60 of the 953, you can check if there are any errors on the CSI input. Note these registers are clear on read, so they will report the number of errors since the last read.

    Also, reg0x61 - reg0x64 will allow you to check the CSI packet header. If you are not getting any data then these registers won't report back any information.
