      I’m having trouble setting up the raspberry pi compute module 3 with the OV9281 board.  I have followed your instructions on your github instructions and so far am getting errors rather than pictures.  When running the ./camera_i2c program in the Utils folder I get the error “setting GPIO for board revision: a02100
      Failed: don’t know how to set GPIO for this board!”

      And when trying to run any file from the folder below I get the error “init camera status = 4099”.  It shouldn’t matter, but I’m using the waveshare IO board.

      Hi,

      For the CM3 board, which is different from other boards. It has two i2c interfaces.

      So, you can’t use the  camera_i2c  script to enable the i2c. You should use our demo for CM3 https://github.com/ArduCAM/MIPI_Camera/blob/master/RPI/preview-camera0.c

      In our code, we will config the i2c interface using

      struct camera_interface cam_interface = {

      .i2c_bus = 0, // /dev/i2c-0 or /dev/i2c-1

      .camera_num = 0, // mipi interface num

      .sda_pins = {28, 0}, // enable sda_pins[camera_num], disable sda_pins[camera_num ? 0 : 1]

      .scl_pins = {29, 1}, // enable scl_pins[camera_num], disable scl_pins[camera_num ? 0 : 1]

      .led_pins = {30, 2},

      .shutdown_pins ={31, 3},

      };

      Thank you for the answer @bin, I’m also having the same issue, and ./preview-camera0 is giving a segmentation fault. has this been tested?

      I believe I have followed all the steps here

      Hi,

      Yes, I have tested it on CM3 module. Have you downloaded our new lib and run make install

      to install the new lib?

      Notice, using the preview-camera0 demo, you should connect the camera to camera1 interface.

      Please try it again and let me know if you need more help.

      Yes I did install the library,

      I got a response on github page yesterday to try an older commit of library and that worked. It seems like there is a bug which was created after April 24th.

      For now I’ll work with the older version and if I catch the bug I’ll submitt a PR.

      Hi,

      Today, I have updated our library and you can try the newest library .

      Let me know if you need more help.
