IMX219 Camera not detected #23

Open DriHut opened 6 days ago

DriHut commented 6 days ago

Hi I just acquired the brand new cb2 which is very cool but when I connect my Camera module 2 to the port on the PI4B adapter I can't get v4l2 to display that the device is there and I still tried to get an image out using ffmpeg or fswebcam but the camera isn't to be found. when running sudo v4l2-ctl --list-devices I get:

rkisp-statistics (platform: rkisp):
        /dev/video7
        /dev/video8

rkisp_mainpath (platform:rkisp-vir0):
        /dev/video0
        /dev/video1
        /dev/video2
        /dev/video3
        /dev/video4
        /dev/video5
        /dev/video6
        /dev/media0

For more precision I installed BTT-CB2_1.0.5_Armbian 23.05.0-trunk Bullseye with Linux 4.19.232-bigtree-cb2 which is the minimal version so that I can run an octoprint instance on it

Hey there. We hear you and we are working on this at the moment. It may take us a week or two to get the drivers sorted out and the image rebuilt.

DriHut commented 6 days ago

Oh thank you for Your quick reply! Wish you luck with that. (Keep us updated)

Scan the CSI camera ov5647 or imx219 device using i2cdetect - y 2, and there will be a device as shown in the picture. The node connected to the device by ov5647 and imx219 is not videoX, but v4l subdev3. The output of the CSI camera is the node video0 output by the ISP, and the stream is obtained from video0. For now, without opening the code stream of cronnest, use the following command to obtain the photo v4l2 ctl - d/dev/video0-- set fmt video=width=640, height=480,pixelformat=NV12 --stream-mmap=3 --stream-skip=3 --stream-to=/usr/nv12.bin --stream-count=1 --stream-poll， The photo is stored in the/usr directory in nv12. bin. imx219 ov5647 scandev

This is an image obtained by cb2 using v1.05 image during the startup of the m8p board. Read the photos of video0 and store them in the usr directory obtain-photo photo

Try using this configuration config

Your current board does not recognize ov5647 or imx219. The address of imx219 is 0x10, and the address of ov5647 is 0x36. You can use Klipper's image to view the stream
