4. Wi-Fi Tools¶
wpa_supplicant, wpa_cli, hostapd and other open source tools are needed when users operate Wi-Fi.
Select Rootfs packages -> Target package wifi and turn on the wireless through the menu mode, archive away and start compiling

Or edit build/boards/{processor_name}/{board_name}/{board_name}_defconfig to enable the following options (as shown below), then execute defconfig $CHIP_$BOARD through command mode to automatically configure
#
# Rootfs packages
#
...
CONFIG_TARGET_PACKAGE_WIFI=y
CONFIG _CP_EXT_WIRELESS=y
# end of Rootfs packages
If users want to update to the latest version, please go to http://w1.fi/releases or http://www.linuxfromscratch.org/blfs/view/svn/basicnet/wireless_tools.html to obtain it, and install it to rootfs yourself.
