For configuring this camera via I2C, the process is not done through v4l2-ctl but directly using a script. Please note the following regarding this script:

If you are using the v4l2 driver mode, camera_i2c_config is not required. When running ./veye_mipi_i2c.sh, make sure to specify the I2C bus you are using with the -b parameter.

Below is an explanation regarding the I2C bus.

For long exposure usage, you may need to configure the lowlight function or the new_mshutter function. Please refer to the corresponding section in the link below.
