BBAI-64 - Any of controls (ex. exposure, gain) for IMX219 sensor are not available with v4l2-ctl --list-ctrls

Hi. Can someone help me with configuring the IMX219-83 Stereo Camera on BBAI64 11.8 2023-10-07 image?

I’ve added BBAI64-CSI0-imx219 and BBAI64-CSI1-imx219 overlays and eventually managed to stream video with motion. But the picture is dim and green. So I wanted to try to tweak camera parameters like gain, exposure e.t.c. and didn’t find any available by:

v4l2-ctl -d /dev/video2 --list-ctrls

I’ve searched the web and found some sources of imx219.c Linux kernel driver (I suppose) where at least V4L2_CID_EXPOSURE and V4L2_CID_DIGITAL_GAIN are supported by the imx219_set_ctrl method.

Any advice? :slight_smile:

Is the stream coming from camera directly to Linux or is it coming through VPAC

New word to me) Have found some ti
pdf to read.
So how can I figure out where the stream is coming from?
Can I try some other solutions to stream video, where I’ll have more control over picture?

So does anyone know that at least one of CSI cameras has proper drivers support on ai64?
