Arducam 64MP and Raspberry Pi Kernel 6 (revisited)

Over a week after my first post and I was still without a working 64mp camera. The old method of running a script to install drivers still reported the same error, and the entry that used to be in my /boot/config.txt file wasn’t helping.

[all]
dtoverlay=arducam_64mp

I went back to look at the arducam forums and came across this post and found that when they went from the custom kernel module install to the standard module install they’ve changed from using an underscore to a hyphen:

[all]
dtoverlay=arducam-64mp

Now after booting, my camera is correctly recognized. The delay and lack of obvious information on their site has been frustrating, but at least I’m up and working and shouldn’t need to do anything special with further apt updates.

Raspberry Pi Kernel 6 and Arducam

I updated the software on my development machine this morning without thinking too much about it. After doing so, I checked my program that uses the camera to see if it was running properly. I’ve got an Arducam64mp camera that I’m using on that machine, and often when the kernel gets updated I need to reinstall the kernel drivers from Arducam. They have a script, so normally it runs easily enough.

Today, it didn’t fix the problem. The script reports an unknown kernel version. I noticed that it’s reporting kernel version 6, which seemed unusual to me. That’s when I switched to my other Pi that I have most of my long term stuff running.

A major bump in kernel version from 5 to 6 was unexpected. Now I’m left with the decision of either waiting to get the 64mp camera working with the new kernel or switching back to one of the PiCamera Model 3 units I have collected recently. Because this is on my development machine, the camera is less important to me than on some of my other units.

I attempted removing the special hooks for arducam to see if the 64mp driver had made it into the standard kernel source tree but no luck with that either.

Enable Raspberry Pi Camera Module 3 Wide after Arducam 64mp

My development pi has had an Arducam 64mp camera connected for my camera software development. I liked the quality of the camera but have at various times been frustrated with the software requirements to use the camera. It’s required both a custom kernel driver and a custom fork of the libcamera software packages. That’s meant that to use the 64mp camera I needed to reinstall the arducam suite after nearly every apt upgrade cycle, and definitely ones where the system kernel got updated.

I spent several days trying to get the remnants of the arducam64mp removed from my development system. I’d even built a fresh sd card image of Raspian Bullseye to make sure that the hardware was all connected and working properly.

In the end the fix was rather simple, if obscure.

First, remove or comment out the dtoverlay line from the /boot/config.txt file and make sure camera auto detect is enabled.

# dtoverlay=arducam-64mp
camera_auto_detect=1

Then run apt install with the –reinstall option for the libcamera packages and the raspberry kernel package.

sudo apt install --reinstall -y libcamera-apps libcamera-dev libcamera0 raspberrypi-kernel
sudo systemctl reboot

Then reboot. That should be then allow you to run libcamera-hello and verify that the new camera is working.

I’d found a reference How To Enable RP Cam V2 After Arducam 64MP that didn’t seem to work for getting the V3 wide camera working, perhaps because the focus hardware in the V3 camera made the 64mp think it was active.

I asked the question of how to remove the drivers on the Arducam Forum and then answered my own question.

On to playing with my new Camera Module 3! (I bought the Arducam cases from Amazon because I really liked the fit. The new wide camera protrudes from the front with enough clearance for the focus to function.)

Arducam 8MP IMX219 175 Degree Ultra Wide Angle Raspberry Pi Camera Module

I’ve been playing with several cameras attached to raspberry pi recently. Getting cameras is easy right now while getting Raspberry Pi is not. I purchased this model from Amazon and have it connected to a Raspberry Pi4. I had to upgrade the unit from running Raspian Buster to Raspian Bullseye to get support for this particular camera.

Amazon Listing

I was doing some searching for red tint problems and fixing them, and it seems to be something that should be able to fix in software. Most of the fixes refer to Jetson Nano, which is not the platform I’m working with, so the fixes don’t align with my platform.

Red Tint Problem on IMX219

I still need to manually focus the lens on this camera. It’s always a frustrating process on a small lens like this because my fingers obscure the view. I’m running with camera_auto_detect=1 while https://www.arducam.com/docs/cameras-for-raspberry-pi/native-raspberry-pi-cameras/8mp-imx219-standard-camera-modules/ recommends modifying /boot/config.txt and setting both camera_auto_detect=0 and dtoverlay=imx219. exiftool reports Camera Model Name : /base/soc/i2c0mux/i2c@1/imx219@10 with the current settings. I’ve verified that using the explicit camera overlay produces the same red tint as well as having exactly the same Model Name in the exif data.

I was able to find the file /usr/share/libcamera/ipa/raspberrypi/imx219.json which may be similar to the ISP files the Jetson platforms were using. I’m still working on the red tint.
