Radxa cm3 sodimm and raspberry camera v2.1

Yo! \(^_^)/

  1. We bought a radxa cm3 sodimm(with rk3566)v1.3 20220927 and plugged it into our board(before that, we used this board for raspberry pi cm3+)
  2. Installed the bootloader(from here https://dl.radxa.com/rock3/images/loader/rock-3a/rk356x_spl_loader_ddr1056_v1.10.111.bin) and the image (from here https://mega.nz/file/hnwjCboL#GSVM3UqpyRCYUQgODHCcOF1A0JieN2qEQ9pu-TNwa6M), and it works!
  3. After that I wanted to check if the camera is working, and do it with fswebcam utility and i did not find any video device to pass it as an argument '(-_-) (camera was connected to mipi-csi0).
  4. In /boot/dtbs/4.19.193-215-rockchip-g2657e70400fc/rockchip/overlay/ i found radxa-cm3s-io-csi1-rpi-camera-v2.dtbo, rk3568-i2c2-m1.dtbo(it is i2c for camera) and with instruction (from here https://wiki.radxa.com/Device-tree-overlays) trying to load overlays. To no avail((

What could i have done wrong?

I think the overlay named “radxa-cm3s-io-csi0-rpi-camera-v2.dtbo”.
The camera can be previewed through cheese tool. But the quality of the picture is not ready yet, we are trying to debug a few days later.


As far as i understand ‘cheese’ tool doesn’t have a cli interface((

I’ve made some progress with my problem:

  1. In order to enbale RPi camera v2 need to pull up GPIO3_D4 (Power Enable pin of rpi camera). I did it. How to change device tree for automatically pulling up this gpio? Because, as i understand, gpio have to pulled up before rpi camera initialization starts. Anybody know when it starts initalizing? :grinning:
  2. I added radxa-cm3s-io-csi1-rpi-camera-v2.dtbo to /boot/extlinux/extlinux.conf in field fdtoverlays and after reboot in /dev appears video0 - video8.
  3. I installed the fswebcam utility and tried to take a test photo:
fswebcam test.png

and get output with error:

--- Opening /dev/video0...
Trying source module v4l2...
/dev/video0 opened.
No input was specified, using the first.
Error selecting input 0
VIDIOC_S_INPUT: Inappropriate ioctl for device
  1. I tried to take a photo with streamer utility:
streamer -o ff.jpeg

and got an error:

libv4l2: error dequeuing buf: Invalid argument
ioctl: VIDIOC_DQBUF(index=0;type=VIDEO_CAPTURE;bytesused=0;flags=0x0 [];field=ANY;;timecode.type=0;timecode.flags=0;timecode.frames=0;timecode.seconds=0;timecode.minutes=0;timecode.hours=0;timecode.userbits="";sequence=0;memory=MMAP): Invalid argument

dmesg after streamer:

I need help :upside_down_face:
