Arducam B0202 (IMX291) not working with Prusalink

[kd4vrf]

PrusaLink type = Raspberry Pi 4

PrusaLink version = PrusaLink 0.8.1

Printer type = MK3s

Printer firmware version = 3.14.1-8237

I had a Logitech C505 and C270 working but the images don't display properly in safari (It did work with Firefox). So I choose a camera off the supported devices list (Arducam B0202) so I could use safari to view the images. However the Arducam B0202 isn't working at all.

I can see the camera but I'm not able to see any images and I can't configure the camera

I connected to Prusalink via ssh and ran "libcamera-hello --list-cameras". It shows no available cameras:
jo@3dPrinter1:~ $ libcamera-hello --list-cameras No cameras available!

In the log file I see the following:

lsusb does show a webcam but it shows up as "Microdia Webcam Vitade AF":

Journal log file shows the device is discovered at boot up:

v4l2 driver appears to recognize the devices properly:

jo@3dPrinter1:~ $ v4l2-ctl --list-devices
bcm2835-codec-decode (platform:bcm2835-codec):
	/dev/video10

USB 2.0 Camera: USB Camera (usb-0000:01:00.0-1.3):
	/dev/video0
	/dev/video1
	/dev/video2
	/dev/video3
	/dev/media2

and video0 appears to support the formats the Prusalink requires:

jo@3dPrinter1:~ $ v4l2-ctl --device /dev/video0 --list-formats-ext
ioctl: VIDIOC_ENUM_FMT
	Type: Video Capture

	[0]: 'MJPG' (Motion-JPEG, compressed)

			Interval: Discrete 0.033s (30.000 fps)

However, Prusalink selects "video2" instead of "video0".

I was able to test the camera by taking a single image using the following command and everything worked as expected and I was able to see a still image of the print bed:

v4l2-ctl --device /dev/video0 --set-fmt-video=width=1280,height=720,pixelformat=MJPG --stream-mmap --stream-to=frame.jpg --stream-count=1

Just out of curiosity I plugged in the Logitech c505 to see if libcamera recognized it since it works just fine in firefox. "libcamera-hello --list-cameras" shows the same output as the non working Arducam module.

`jo@3dPrinter1:~ $ libcamera-hello --list-cameras
No cameras available!`

I was thinking that it was a libcamera issue and I was going to start troubleshooting there but it doesn't seem to matter since the working logictech c505 shows the V4l2 drivers in the status screen and doesn't show available to libcamera even though it works.

Let me know if you need any additional information
