Hello Nvidia Team,
We are using Orin NX (16 GB) module + avermedia d131 kit with ov5640 camera sensor.
& facing difficulty while bringing it up.
Driver used : /drivers/media/i2c/ov5640.c (in kernel-source.)

Kernel panic seems to be occurend by kernel-source/nvidia/drivers/media/platform/tegra/camera/vi/channel.c [ line :1335].
case TEGRA_CAMERA_CID_VI_PREFERRED_STRIDE:
chan->preferred_stride = ctrl->val;
tegra_channel_update_format(chan, chan->format.width,
chan->format.height,
chan->format.pixelformat,
&chan->fmtinfo->bpp,
chan->preferred_stride);
Could anyone please let us know the reason behind kernel panic when inserting ov5640.ko driver.
Thanks & Regards,
