Please check the kernel version, we only provide the driver for the latest official kernel version image when this Pivariety camera is released.

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 19

If you find the same error, you may make the wrong selection about the graphics driver.

For Raspbian Bullseye users running on Pi Zero ~ Pi 3, please execute the follows:

1. Open a terminal
2. Run sudo raspi-config
3. Navigate to Advanced Options
4. Enable Glamor graphic acceleration
5. Reboot your Pi

Meanwhile, you also need to execute the following steps:
1. Open a terminal
2. Run sudo raspi-config
3. Navigate to Advanced Options
4. Navigate to GL Driver
5. Select GL (Full KMS)
6. Reboot your Pi

For more details, please refer to the official forum guide on how to configure the camera module >>

For Raspberry Pi Compute Module 3/4

You need to install the latest Raspberry Pi system (after 2022/01/28), and do not execute rpi-update
After installing the system and drivers (follow the above instructions), add the following information to /boot/config.txt:
[cm4]
dtoverlay=imx519
dtoverlay=imx519,cam0

Then reboot.

List all cameras:
libcamera-still –list-cameras

Specify camera:
libcamera-still -t 0 –camera 0
libcamera-still -t 0 –camera 1

5. Open I2C bus error

Solution:

sudo raspi-config

–> Interface Options

–> I2C

6. Switch to the native camera (raspistill etc.)

If you want to use other cameras that needs Native driver, you can edit the file of /boot/config.txt, make dtoverlay=arducam and change to # dtoverlay=arducam.
