# 修改官方AX86U预设的内核配置，其他设备自测
vi ~/asuswrt/release/src-rt-5.02p1axhnd.675x/kernel/linux-4.1/config_base.6a.62118

# 例如将USB转串口驱动option模块编进内核，将以下默认的值设置为y
CONFIG_USB=m
CONFIG_USB_SUPPORT=y
CONFIG_USB_COMMON=m
CONFIG_USB_SERIAL=m
CONFIG_USB_SERIAL_WWAN=m
CONFIG_USB_SERIAL_OPTION=m
CONFIG_USB_SERIAL_CONSOLE=m


# 也可通过字符界面配置内核， config_rt-ax86u需要编译一次才会出现，因为它是几个文件合成的
cd ~/asuswrt/release/src-rt-5.02p1axhnd.675x/kernel/linux-4.1/
make ARCH=arm64 menuconfig config_rt-ax86u

# 例如为默认BUSYBOX添加MICROCOM支持
vi ~/asuswrt/release/src/router/busybox-1.24.1/busybox-1.24.1/config_base
CONFIG_MICROCOM=y		# 修改或添加该行

# 编译完成后可使用microcom操作模块，Ctrl + Z 退出
microcom -s 115200 /dev/ttyUSB2
