Hello,
I am trying to get video data from IMX274 with using CSI2. But when I execute gstreamer command, nvcamera-daemon stopped working.
Here is dmesg about the error:

cam_module5_drivernode0: drivernode0 {

};
cam_module5_drivernode1: drivernode1 {

};
};
};
};
Note:
I changed i2c settings as you can see in the device tree, and after that I checked the i2c lines and this configuration seems correct. And imx274 probe and vi probe finished successfully, so I can see video0 in /dev directory.
So, Do you have any idea what is the problem ?
What does nvcamera-daemon say in the error code?
Thanks,
Şükrü.
