Note: If you want to compile the kernel driver by yourself, please refer to How to build Raspberry Pi Kernel Driver-Pivariety Camera.
4. Failed to import fd 18
If you find the same error, you may make the wrong selection about the graphics driver. Please refer to the chapter of Select the correct graphics driver.
5. Switch to the native camera (raspistill etc.)
Edit the file of /boot/config.txt, make dtoverlay=arducam change to # dtoverlay=arducam
After the modification is completed, you need to reboot the Raspberry Pi.
