Hi,
I am trying to get DM3730 to work with ADV7180 i2c driver and I realize there is this media controller framework that omap3isp uses.
Is it necessary to patch ADV7180 driver with media controller framework or is there other way to bypass the ISP and use the driver direct?
If media controller framework is the suggested solution, is there any guide that I can reference?
I have attempt patching ADV7180 with media controller framework with the following issues:
Encounter error with yavta when opening stream.
I am trying to pipe adv7180->ccdc->ccdc output and use yavta to test, the following is some of the output I captured:
