DS90UB964-Q1EVM: Length count, Line count information in ALP.

Part Number: DS90UB964-Q1EVM
Other Parts Discussed in Thread: ALP

Hello Team,

Sorry for simple question.

pls understand that I have no way to verify this register 

My customer is using 913A and 964 for Surroud view.

they reported that ALP shows only PCLK but there is no information of Line length and line count in ALP info tap.

So Is there any register configuration needed to see those information??

I already confirmed their sensor send Hsync/Vsync to SER.

Thank you.

    Hello Harry,

    I am not sure if I understood you correctly. Are you looking for registers where to read the Line length and line count on the UB964?

    If yes, these can be found in reg 0x73, 0x74, 0x75, 0x76

    Hello Hamzeh,

    Thanks for your quick reply.

    Yes I also know this register.

    I got timing log in ALP by using this script

    .

devAddr = 0x7a
serAddr = 0xb0

    After change FV polarity in 0x7c, I got timing information finally.

    I have 1 quick question here.

    now, image sensor input is 8bit RAW with 1280x944

    but I could see Horizontal : 2560byte and verital : 944.

    is this log correct? I think it should be 1280 because of color depth is 8bit RAW.

    Could you pls help me clarify this??

    Thanks

    Hello Harry,

    may be the Imager is working in double-exposure mode?!

    Double exposure???

    Now, I just remember that input PCLK from Imager is 94MHz but 964 side log in ALP shows it is 47Mhz.

    is this also related with double exposure??

    Thanks for your support all the time~

    No, PCLK has nothing to do with double exposure. This is a settings on the Image sensor, which allows to send two pixels instead of one, one is short and the other is long.

    Please contact the Imager vendor and clarify.

    Hello Hamzeh,

    Yes. I was told this information is wrong from camera company.

    Let me close this.

    Thanks for your support~
