sdk-ai 代码已更新。请拉取最新的代码。
执行以下步骤：
./build.sh device/rockchip/rv1126_rv1109/aio-rv1126-rkmedia-uvcc.mk
./build.sh

CORE-1126-JD4/CORE-1109-JD4 设备默认没有开启 OTG 功能，请先在内核开启 OTG，编译升级内核。

workaroud 解决:

$ cp * /home/ws/AI_UVC_CAM-CRV1126S2U/buildroot/output/firefly_rv1126_rv1109_rkmedia_uvcc/build/firefly_rkmedia_uvc-1.0/uvc/
cp#

2. 此贴的主题问题,uvc的demo 如何正确运行呢?

2.1 如下默认方法执行失败,执行完这一步后adb 连接就断开了. 用adb ip:5555 shell 也不行.
/oem/usb_config.sh rndis

2.2 删除/etc/init.d/S58_lunch_init 后重启 adb 无法连接.
这个文件夹里面还有其他S**_lunch_init, 不确定删哪一个.

2.3 cd /oem;./RkLunch-stop.sh 之后再重复上述步骤2.1也无效.

使用以下 mk 文件编译出来的固件可以直接使用，不用操作板子。
./build.sh device/rockchip/rv1126_rv1109/aio-rv1126-rkmedia-uvcc.mk

固件烧进板子之后。电脑查看 /dev/video 是哪个节点，根据出现的节点修改 client.cpp 。
修改以下内容：
#define VIDEO_NODE 1

编译执行：
cd sdk-ai-path/app/firefly_rkmedia_uvc/host/
./build.sh
sudo ./client
#正常运行的话就能看到信息了
#程序还没完善，只能运行一次。想要再次打开只能重启板子。

太赞了, 已经导通!

可否再麻烦请教一下,查看video设备的话,其实Core-1126-JD4核心板会显示如下两个video设备.
我目前用的是video8, 请教一下和video9 有什么区别?
