Please check the kernel version, we only provide the driver for the latest official kernel version image when this Pivariety camera is released.
If you find the same error, you may make the wrong selection about the graphics driver.
sudo raspi-config
–> Interface Options
–> I2C
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.
After the modification is completed, you need to reboot the Raspberry Pi.
sudo rebootAt present, there is a memory allocation problem with Arducam 64MP Camera Module when shooting at the maximum resolution on the Raspberry Pi, and the performance is as follows:
There is no perfect solution for this problem currently, but we provide some methods to solve it:
We used Pi4B-8G, Pi4B-1G, Pi3B-1G for a long time test, the test results show that Raspberry Pi OS Lite is more stable when using Arducam 64MP Camera to shoot at the maximum resolution (so far we have not found any failures).
Modifying the preview resolution to a smaller resolution can also improve the success rate of shooting 64MP resolution images, example command:
libcamera
-
still
-
t
5000
--
viewfinder
-

2312
--

cmdline.txt
Note
The cma value of all tests is 512M (add dtoverlay=vc4-kms-v3d,cma-512 in /boot/config.txt)
If you want the stable 64MP Resolution images, we recommend you using Raspberry Pi OS Lite, we will find more solutions for this issue continuously.
Saving pictures with Arducam 64MP Camera will take a lot of time because of the need for coding：
You can see that it will take more that two seconds to save the image.
At this situation, you can write a program that uses multi-threading to take out the data and save it with another thread.

Some users may experience lateral streaks on images when shooting at maximum resolution with the Arducam 64MP autofocus camera, as follows:
This problem may be related to the noise reduction function of the Raspberry Pi platform ISP, and the solution is as follows:
Add the --denoise cdn_off parameter when taking pictures, such as:
libcamera-still -t 5000 --denoise cdn_off --viewfinder-width 2312 --viewfinder-height 1736 --width 9152 --height 6944 -o arducam_64mp.jpgSome customers have reported that when running capture_full_res.py (one of the picamera examples on Raspberry Pi GitHub repository), the camera and program will freeze, and only Ctrl + C can be used to exit. You can refer to this issue for more information. Arducam has provided a temporary solution. Please contact Arducam (support@arducam.com) and provide your Raspberry Pi kernel version, such as 6.1.21.
Arducam will send you a customized driver version for your kernel via email. Please transfer the compressed package to your Raspberry Pi and follow the steps below:
Please comment out the dtoverlay=arducam-64mp in the config file(run the command sudo nano /boot/config.txt, scroll down to the bottom,you will see this sentence).
Run the commands below to unzip the package and install the camera driver.
tar -xvf arducam_64mp_kernel_driver_6.1.21.tar.gz Release/cd
Release/
Release/
./install_driver.shTo this point, you need to restart Raspberry Pi to take effect. You can retry the capture_full_res.py to check if the problem is solved.
Kindly note that the customized driver may not be suitable for all Raspberry Pi camera modules and kernel versions. And the customized 64MP driver that we sent you, we will upstream it to the Raspberry Pi kernel in the future.
Environment Preparation
Please first keep the kernel version on 6.1.63 and later
+
'uname -v | grep -oP '
\d
+
\.

'
If the kernel version is earlier than 6.1.63, please use the following command to update the kernel and restart the system after the update.
sudo
apt
-
get
update
sudo
apt
-
get
upgrade
Please do not use sudo rpi-update to upgrade the kernel to a particularly new version
All of our support is based on stable versions of the kernel, currently for using Arducam 64MP Hawkeye camera on bookworm, our supported kernel list is:
6.1.63

To solve this problem, we need to modify the camera's front-end driver.
rp1-cfe.ko.xz
First, you need to switch the system version to the 5744 branch. After the command is executed, you need to restart the Raspberry Pi to take effect.
sudo
rpi
-
update

/
5744
sudo
reboot
