iMX6DL : How to recognize a SAV/EVA code ?

koichisakagami — Tue, 09 Feb 2016 11:06:05 GMT

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
