Composite Video Input - Verdin iMX8M Plus

Technical Support

Good Morning,

The carrier board I am working for a Verdin iMX8M Plus is required to have a single-ended composite video input. Has this been done before?

I was hoping to use the below Analog IC, which can convert the video to CSI, but it seems like there are no drivers for it.
ADV7280A (Rev. A) (analog.com)

Any help would be appreciated!
Tom

Hello @forstnert ,
To our knowledge, at least one customer of us has integrated this video decoder, but unfortunately we don’t have the technical details of their integration.

Would you be OK by using a 3rd party driver developed by them? If so we could try to put you in contact with them.

Best regards,
Josep

Hello @forstnert ,
In the menatime, maybe you already went through this, but just in case:

Another option could be to enable the ADV7180 driver, it seems that it also supports ADV7280M adv7180.c - drivers/media/i2c/adv7180.c - Linux source code (v6.3) - Bootlin

static const struct of_device_id adv7180_of_id[] = {
	{ .compatible = "adi,adv7180", },
	{ .compatible = "adi,adv7180cp", },
	{ .compatible = "adi,adv7180st", },
	{ .compatible = "adi,adv7182", },
	{ .compatible = "adi,adv7280", },
	{ .compatible = "adi,adv7280-m", },
	{ .compatible = "adi,adv7281", },
	{ .compatible = "adi,adv7281-m", },
	{ .compatible = "adi,adv7281-ma", },
	{ .compatible = "adi,adv7282", },
	{ .compatible = "adi,adv7282-m", },
	{ },

Best regards,

Hello @forstnert ,

Jut FYI, it is possible to enable the ADV7180 driver via menuconfig:
it is already available in our source i2c « media « drivers - linux-toradex.git - Linux kernel for Apalis, Colibri and Verdin modules

Since you use ADV7280A this should be no problem:
