Dear community,
    We have been developing our product with iMX6DL.

    We try to capture 8-bit ITU BT656 format data using CSI0 interface. However, it does not work correctly.
    We hope to find the problem points.

    First of all, we want to check that a SAV/EVA code is detected.

[Question]
    Could you tell us the way to detect the SAV/EVA code ?

    What kind of  status register field should we check ?

    Best Regards,
    Koichi Sakagami

Hi Koichi

I am afraid there is no status register indicating detection the SAV/EVA code.

Since IPU data is handled by IDMAC, one can try to check RM

sect.37.4.2.14 IDMAC's internal events, check IPUx_INT_CTRL

indicating End Of Frame of Channel #n.

Best regards

igor
