请问下，该文档中的脚本mount -t configfs none /sys/kernel/config
mkdir /sys/kernel/config/usb_gadget/rockchip -m 0770
echo 0x2207 > /sys/kernel/config/usb_gadget/rockchip/idVendor
echo 0x0019 > /sys/kernel/config/usb_gadget/rockchip/idProduct
echo 0x0100 > /sys/kernel/config/usb_gadget/rockchip/bcdDevice
mkdir /sys/kernel/config/usb_gadget/rockchip/strings/0x409 -m 0770
echo "0123456789ABCDEF" > /sys/kernel/config/usb_gadget/rockchip/strings/0x409/serialnumber
echo "rockchip" > /sys/kernel/config/usb_gadget/rockchip/strings/0x409/manufacturer
echo "USB Audio Device" > /sys/kernel/config/usb_gadget/rockchip/strings/0x409/product
mkdir /sys/kernel/config/usb_gadget/rockchip/configs/b.1 -m 0770
mkdir /sys/kernel/config/usb_gadget/rockchip/configs/b.1/strings/0x409 -m 0770
echo 500 > /sys/kernel/config/usb_gadget/rockchip/configs/b.1/MaxPower
echo "uac1" > /sys/kernel/config/usb_gadget/rockchip/configs/b.1/strings/0x409/configuration
mkdir /sys/kernel/config/usb_gadget/rockchip/functions/uac1.gs0
ln -s /sys/kernel/config/usb_gadget/rockchip/functions/uac1.gs0
/sys/kernel/config/usb_gadget/rockchip/configs/b.1/uac1.gs0
echo ff400000.usb > /sys/kernel/config/usb_gadget/rockchip/UDC
该脚本是需要自己添加到哪里执行，还是说我自己在output/rockchip_rk3308_release/target/rockchip_test 自行添加进去，板子开启之后自己执行？
如果是这样的话会提示Permission denied 错误，如果是需要添加到开机自行配置运行的话，可否告知该添加的流程？
