Two Separate MIPI-CSI Input Streams for Stereo Vision

Hello NXP Team,

I have a question for you about the i.MX 8M Plus ISP capability that I was not able to find an answer to by reading the i.MX 8M Plus documentation.

We have our stereo vision cameras already working with the NXP development board, but we want to plan accordingly for finalization of a camera adapter board for our own system.

When targeting our system, we will have access to a camera on a x4 MIPI CSI lane and another camera on a x2 MIPI CSI lane. I wanted to verify whether the integrated ISP could support simultaneous input from two separate camera input streams for a stereo vision application. Is this possible with the support in place for the ISP today?

Thanks,

-Kevin

yes, imx8mp can support dual camera via different ISP , you can refer to the basler dts file as reference, which supports two 4-lanes basler via dual ISP
