imx8QM capture camera stream with MAX9296

[YaosongHu]

Hello Community:

  I'm using a imx8QuadMax MEK to capture camera stream by MAX9296.

  My Yocto is LF5.15.5_1.0.0.

  Now I have done MAX9296 driver by imitating the driver of MAX9286 at drivers/staging/media/imx/gmsl-max9286.c as attch shown. I enable dev_dbg function for csi and isi drivers to get register value.

  When I run ./mx8_v4l2_cap_drm.out -cam 1 -fmt YUYV -of, I get isi IRQ Panic OFLW Error.  Below is kernel print I got:

  Could someone please tell me what configures should I check?

Thanks.

Hi @YaosongHu,

I hope you are doing well. I appreciate your cooperation.

Could you please provide me with the output of the following command?

# v4l2-ctl -D -d /dev/video1

Thank you.

Best Regards,
Dhruvit.
