Description

1.打开USB以太网内核配置

diff --git a/kernel/arch/arm64/configs/rockchip_linux_defconfig b/kernel/arch/arm64/configs/rockchip_linux_defconfig

2.重新编译kernel

./build.sh kernel

3.编译完成后将内核烧录到设备中，烧录过程请用户参考相应板卡维基的升级固件页面。然后将内核目录下生成的下列模块复制到设备中：
  • drivers/usb/gadget/libcomposite.ko
  • drivers/usb/gadget/function/u_ether.ko
  • drivers/usb/gadget/function/usb_f_ecm_subset.ko
  • drivers/usb/gadget/function/usb_f_ecm.ko
  • drivers/usb/gadget/function/usb_f_rndis.ko
  • drivers/usb/gadget/legacy/g_ether.ko

3.然后在设备上，依次加载上述模块：

insmod libcomposite.ko
insmod u_ether.ko
insmod usb_f_ecm_subset.ko
insmod usb_f_ecm.ko
insmod usb_f_rndis.ko
insmod g_ether.ko

注意： 要先加载 libcomposite.ko 和 u_ether.ko，后面的模块才可以加载进去。
