Tool/software:
Platform: AM62P
sensor: four ISX031 （1920x1080 @25fps）nv12
SERDES：MAX92717+MAX96724
1)
As log log_ioctl.txt show:
when app call: enum v4l2_buf_type type = V4L2_BUF_TYPE_VIDEO_CAPTURE;
ret = ioctl(fd, VIDIOC_STREAMON, &type);
error occur in v4l2-subdev.c:
v4l2_subdev_enable_streams->
if (found_streams != streams_mask) {
dev_dbg(dev, "streams 0x%llx not found on %s:%u\n",
streams_mask & ~found_streams, sd->entity.name, pad);
ret = -EINVAL;
goto done;
}
// found_streams =0
// streams_mask =1
As the code show, I need to add stream_configs in my sensor dirver?
2) As log log_media-ctl.txt show:
only one route found in entity 9: cdns_csi2rx.30101000.csi-bridge.
(expect 4 route )
how to add route in app or kernel?
