V853怎么配置单目摄像头？
-
V853做的板子，buildroot系统，要适配一个gc2503 4land的单目摄像头,，看了文档都是双目的，弄了好久没有弄出图像来，不知道怎么搞了，求指导。以下是做过的操作：
1、DTS的vind节点如下：vind0:vind@0 { vind0_clk = <200000000>; status = "okay"; csi2:csi@2 { pinctrl-names = "default","sleep"; pinctrl-0 = <&ncsi_pins_a>; pinctrl-1 = <&ncsi_pins_b>; status = "disabled"; };

Octops:/server/camera# ls csi_test_mplane v4l2_demo videobuf2-v4l2.ko da380.ko videobuf2-core.ko vin_io.ko gc2053_mipi.ko videobuf2-dma-contig.ko vin_v4l2.ko ism.sh videobuf2-memops.ko Octops:/server/camera# Octops:/server/camera# cat ism.sh insmod videobuf2-core.ko insmod videobuf2-memops.ko insmod videobuf2-dma-contig.ko insmod videobuf2-v4l2.ko insmod vin_io.ko insmod gc2053_mipi.ko insmod vin_v4l2.ko Octops:/server/camera# ./ism.sh [ 90.451429] [VIN_WARN]sensor_helper_probe: cannot get sensor0_cameravdd supply, setting it to NULL! Octops:/server/camera# Octops:/server/camera# ls -l /dev/video0 crw-rw---- 1 root video 81, 0 Jan 1 01:51 /dev/video0 Octops:/server/camera#3、执行csi_test_mplane如下：
Octops:/server/camera# ./csi_test_mplane open /dev/video0 fd = 3 resolution got from sensor = 640*480 num_planes = 3 VIDIOC_STREAMON ok file length = 307200 76800 76800 file start = 0xb6eee000 0xb6edb000 0xb6ec8000 Got signal 11, exiting ...

VIDIOC_STREAMOFF ok mode 1 test done at the 0 time!! time cost 1.221462(s)4、i2cdetect测试，发现器件地址对不上
Octops:/server/camera# i2cdetect -y 1 0 1 2 3 4 5 6 7 8 9 a b c d e f 00: -- -- -- -- -- -- -- -- -- -- -- -- -- 10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 30: -- -- -- -- -- -- -- UU -- -- -- -- -- -- -- -- 40: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 50: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 60: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 70: -- -- -- -- -- -- -- --问题：
1、想确认下，4land的摄像头，需要专门指定4land吗？怎么指定？
2、出现了video设备是可以说明硬件通了，只需要做软件的调试吗？
3、为什么器件地址会变为原来的一半？
4、有什么办法可以实时预览摄像头吗？
