Develop a custom driver renessas ISL9887 MIPI-CSI 2 for Jetson AGX Orin

[chakibdace]

Hi all,

We’re using a setup of analog cameras with a renessas ISL9887 4-Channel Differential Input Video Decoder with MIPI-CSI2 output, renessas ISL9887 is the video source, we want to develop a V4L driver where the Jetson AGX Orin will capture the video frames through v4l2 using the MIPI-CSI2 interface, in fact that the renessas ISL9887 has MIPI-CSI2 output interface and the Jetson AGX Orin also support this latter.

The attached image below show what kind of setup, we want to use

Can you please give some reference to such a driver for Renessas ISL9887 MIPI-CSI 2 ?

Can you also please suggest which module can we use to interface the ISL9887 has MIPI-CSI2 with the Jetson AGX Orin to be able to capture the frames using V4L2 interface ?

Thanks

You can reference to tegra234-p3740-0000-camera-imx390-a00.dtsi for virtual channel support.
And using v4l2-ctl or v4l2src to capture the frames.

@ShaneCCC do you any reference about the Camera Interposer Module hardware which can be used to connect Renessas ISL9887 eval board to DeveloperKit CarrierBoard ?

Can you explain please why we have to use virtual channel ?

[ShaneCCC]

Sorry we don’t have it. However you can check with camera partners.
I just release you want to design virtual channel support sensor board you can just ignore it.

@ShaneCCC Can you provide some useful links to be able to develop such a driver please ?

Below is sensor programing guide.
