Enabling and disabling MIPI CSI 2 camera drivers

Enabling and disabling MIPI CSI-2 camera drivers on NXP boards

By default, the camera driver modules of MIPI CSI-2 cameras from Allied Vision and Omnivision are loaded. You can enable or disable driver modules either permanently or until the next bootup.

Note that Allied Vision’s driver avt_imx6_csi2 is built on NXP’s driver mxc_v4l2_capture. Therefore, mxc_v4l2_capture must be enabled to use Alvium CSI-2 cameras.

To disable or enable a MIPI CSI-2 driver module until the next bootup:

# List all loadable modules 
lsmod

# Disable modules
sudo rmmod ov5642_camera 

# Depends on mxc_v4l2_capture, v4l2_int_device
sudo rmmod avt_imx6_csi2 

# Depends on mxc_v4l2_capture, v4l2_int_device
# Keep enabled to use your camera
sudo rmmod mxc_v4l2_capture 
sudo rmmod v4l2_int_device

# Enable a module
sudo modprobe avt_imx6_csi2

To disable the Omnivision driver module permanently, go to /etc/modprobe.d/blacklist.conf and append a line with the driver module you want to disable:

#  Go to the end of the .conf file. Append a line with the driver module you want to disable
blacklist ov5642_camera
