RK3588 usb otg口实现UVC gadget,作为usb camara向windows 传输图像
1、打开内核相关配置
CONFIG_VIDEO_V4L2_SUBDEV_API=y
CONFIG_MEDIA_USB_SUPPORT=y
CONFIG_MEDIA_CONTROLLER=y
CONFIG_USB_VIDEO_CLASS=y
CONFIG_USB_VIDEO_CLASS_INPUT_EVDEV=y
CONFIG_V4L_PLATFORM_DRIVERS=y
CONFIG_MEDIA_CAMERA_SUPPORT=y
CONFIG_VIDEO_DEV=y
CONFIG_USB_CONFIGFS_F_UVC=y
2、安装uvc-gadget
git clone https://git.ideasonboard.org/uvc-gadget.git/
cd uvc-gadget
git checkout v0.1.0 //最新0.3.0版本依赖libcamara,回退到0.1.0
sudo apt-get update
sudo apt-get install build-essential
sudo apt install python3-pip
sudo pip3 install meson==0.63
sudo pip3 install ninja
meson build
ninja -C build
3.修改uvc-gadget/scripts/uvc-gadget.sh脚本
diff --git a/scripts/uvc-gadget.sh b/scripts/uvc-gadget.sh
index dceecd9..3476da0 100755
--- a/scripts/uvc-gadget.sh
+++ b/scripts/uvc-gadget.sh
@@ -176,7 +176,10 @@ case "$1" in
echo "Creating the USB gadget"
#echo "Loading composite module"
#modprobe libcomposite
-
+
+ umount /sys/kernel/config
+ mount -t configfs none /sys/kernel/config
+
echo "Creating gadget directory g1"
mkdir -p $GADGET/g1
4、关闭系统自带usb adb,然后重启
sudo systemctl disable usbdevice
5、测试uvc功能
①进入...uvc-gadget/scripts 目录
sudo ./uvc-gadget.sh start
②进入....uvc-gadget/build/src
sudo ./uvc-gadget -c /dev/videoxx //videoxx为插入的usb摄像头的设备节点,###### windows主机 bus hound会探测到UVC camara,用AMCap可以看到摄像头图像
