Hello.

 

Currently I am working on driver integration task for adv7280-m chip.

 

And I got issue related to mipi csi clock. Mipi dphy driver detect Clock line as ULPS(ultralow power state).  You can see my oscilloscope images in this branch adv7280-M clock problem | EngineerZone .

 

I am trying to understand what could be the reason of issue: adv7280-m chip or imx6. Could anybody, who  worked with this adv7280-m chip show me your signals on the mipi lines or analize my signals.

 

I also interested in what should be switched on first: the decoder chip mipi dphy or  imx6 mipi dphy.

 

As I understand. there are a lot of people who managed to get workable adv7280-m chip with imx6. Could you also share your mipi csi2 driver settup

 

Thanks.
