Good morning,
Working on i.MX6 Dual Lite with Android Nougat N7.1.1_1.0.0(kernel 4.1.15).
I integrated camera driver OV5640 with auto focus feature. Video and auto focus work well.
One trouble remains. On camera app, when I touch the screen to focus on a target point, a circle appears but auto focus doesn't start. Auto focus only works on app launch/wake up.
Problem comes from file : kernel_imx/drivers/media/platform/mxc/capture/ov5640_mipi.c (attached file)
function : ioctl_s_ctrl - V4L2 sensor interface handler for VIDIOC_S_CTRL ioctl
The function handler is never called. How can I register/link it to screen touch event ?
Best regards,
Pierre
