Can not open V4L2 driver dev/video

Hello Guys,

We followed imx135_v4l2.c to create ov10633 driver and modified board file to fit ov10633 property.
After input command as,

  1. rmmod nvhost_vi
  2. insmod ov10633.ko
  3. modprobe tegra_camera
  4. ls /dev/video*

The TK1 reply ls: cannot access /dev/video*: No such file or directory

Pls help to create V4L2 I2C camera driver nodes and registration. Any help will be sincerely appreciated. Thanks.

Hi Drexler,

Please check the V4L2 User Guide for Jetson TK1 inside the Tegra_Linux_Driver_Package_Documents_R21.4, it describes the driver development.

Do you have datasheet with register definitions? You could try user space I2C and GPIO access to the camera to make sure you can power it up and write/read camera registers.

Thanks
