Hi Team

I would like to ask a question, should the polarity of MIPI data lane be modified according to the register shown in the figure below?
1. If we want to modify the data lane 0 polarity, is it set to 0x20, 0x01
2. Or need another settings? THX

    Hi Kygo,

    if you want to change Data Lane 0 polarity, you should write 0x01.

    Hi 

    Thank you !

    1. Could you please checking the SCH of  DS90UB953-Q1

    2.We tried this yesterday and it didn't seem to work. After we downloaded 0x20 set 0x01, the MIPI on the TI954 side will not output.

    Now we want to swap the pair of CSI_D0P and CSI_D0N, P to N, N to P.
    Does TI953 support this function?

    Hi Kygo,

    we have tested that and we know it should work. If you want to swap the pair of CSI_D0P and CSI_D0N, P to N, N to P on the UB953 then you should write reg 0x20=0x01, as I said. I do not have any other solution!

    For the schematic review, please open a new ticket with a title which should reflect the content of the ticket.
