1, modify Makefile
Find the following 2 places to change to
ARCH? = Arm
Cross_compile? = arm-linux-

2. Open the Configuration menu
Make Menuconfig
Here are some configurations, turn on TAB completion, check ifconfig, turn on the driver loading function, etc.
You can search by/after entering characters
