DS90UB954-Q1: Failed to configure the output of 4lane CSI.

Part Number: DS90UB954-Q1

Hi 

954 can accept 12-bits of DATA + 2SYNC bits through RIN0+/- but we failed to configure the output of 4lane CSI.    

At present, no reason has been found.       

1. Please help to  confirm which registers need to be configured for output.

Our data stream is ar0144 - > ds90ub913 - > ds90ub954 - > SOC

2. Are there any omissions and mismatches in the output-related parts of my configuration?

3. Our 954 register.

Thank you

Jerry

    Jerry,
    for the stream "ar0144 - > ds90ub913 - > ds90ub954 - > SOC", please check what is the AR0144 output video format? it is yuv422_8_8 or other?
    if it is YUV422_8_8, you can set the mode_sel of UB954 as RAW10 mode. and UB954's reg. 0x70 RAW10 data type should be configured as YUV422_8_8.
    you can refer to DS90UX960 EVM user guide page22, it has one script for your reference.

    regards,
    Steven
