Hello,
I am interested in the signal quality of the camera stream across different cables, including different length CSI cables and the types of CSI to HDMI or CSI to USB conversion boards that you can find from various sources like Arducam. The images look perfect when you use these alternatives to the stock CSI cable, but it's hard to know if some of the pixels are corrupted. If we could generate the test pattern modes that are part of the IMX219 spec sheet or other raspberry pi compatible cameras, then we could compare the output through these various cables and determine if there is any appreciable signal loss.
I have seen some discussion on the forums mentioning that maybe this is possible with v4l2-ctl, but I'm not sure how to enable it, if anyone can point me to an example or the right direction it would be much appreciated
Best,
Leo
