January 26, 20242 yr Hi all, I am trying to get an OV5640 camera working on the orangePiOne. I found this thread and was wondering if the overlay (or some overlay) is still required. Without anything extra, the camera is not detected. It says that sun6i-csi and ov5640 kernel modules should be loaded, so I loaded them manually with modprobe but nothing happens and nothing is shown in dmesg. Adding the mentioned overlay with "sudo armbian-add-overlay csi-ov5640.dts" just gives me an error in dmesg at reboot time "failed on fdt_overlay_apply(): FDT_ERR_NOTFOUND Error applying DT overlays, restoring original DT" uname -a Linux orangepione2 6.1.63-current-sunxi #1 SMP Mon Nov 20 10:52:19 UTC 2023 armv7l GNU/Linux boot logs on https://paste.armbian.com/unoqesepov wondering what to try next...

January 26, 20242 yr Author thanks, I tried that overlay now and there is some progress. A new device appeared in /dev/video, and I can see with lsmod that sun6i-csi and ov5640 kernel modules were loaded. However, trying ustreamer (https://github.com/pikvm/ustreamer) which I have used on the same board with a usb camera, unfortunately fails bruno@orangepione2:~$ sudo ustreamer --device=/dev/video0 --host=0.0.0.0 --port=8080 --resolution 1920x1080 -- INFO [680.044 main] -- Using internal blank placeholder -- INFO [680.045 main] -- Listening HTTP on [0.0.0.0]:8080 -- INFO [680.046 stream] -- Using V4L2 device: /dev/video0 -- INFO [680.046 stream] -- Using desired FPS: 0 -- INFO [680.047 http] -- Starting HTTP eventloop ... ================================================================================ -- INFO [680.049 stream] -- Device fd=8 opened -- INFO [680.049 stream] -- Using input channel: 0 -- INFO [680.049 stream] -- Using resolution: 1920x1080 -- INFO [680.049 stream] -- Using pixelformat: YUYV -- INFO [680.050 stream] -- Querying HW FPS changing is not supported -- INFO [680.050 stream] -- Using IO method: MMAP -- INFO [680.075 stream] -- Requested 5 device buffers, got 5 -- ERROR [680.076 stream] -- Unable to start capturing: Broken pipe -- INFO [680.081 stream] -- Device fd=8 closed -- INFO [680.081 stream] -- Sleeping 1 seconds before new stream init ... ================================================================================ I am going to try other formats, sizes and fps, see if it makes any difference...
