全志V853 摄像头初体验

1. 选上SDK里面的摄像头demo

make menuconfig --->
	Allwinner  --->
		eyesee-mpp  --->
			[*]     mpp sample virvi2vo

2. 在sdk根目录下执行cmpp_p，然后打开Makefile，修改：

kunyao@AwExdroid89:~/workspace/a_tina/package/allwinner/eyesee-mpp/middleware$ git diff .
diff --git a/allwinner/eyesee-mpp/middleware/Makefile b/allwinner/eyesee-mpp/middleware/Makefile
index 37cb9be5e..454b9045d 100755

3. roofs改到，不然pack的时候会报错

tina/device/config/chips/v853/configs/vision/linux$ git diff .
diff --git a/configs/vision/linux/sys_partition.fex b/configs/vision/linux/sys_partition.fex

     downloadfile = "rootfs.fex"
     user_type    = 0x8000

4.重新编译打包把固件烧到开发板里去

sample_virvi2vo /usr/sample_virvi2vo.conf

摄像头开启，屏幕显示实时预览
