Current Target: "ar71xx (Generic devices with NAND flash)"
Default Packages: base-files libc libgcc busybox dropbear mtd uci opkg netifd fstools kmod-gpio-button-hotplug swconfig kmod-ath9k wpad-mini uboot-envtools dnsmasq iptables ip6tables ppp ppp-mod-pppoe kmod-ipt-nathelper firewall odhcpd odhcp6c
Available Profiles:

WNDR4300:
        NETGEAR WNDR3700v4/WNDR4300
        Packages: kmod-usb-core kmod-usb-ohci kmod-usb2 kmod-ledtrig-usbdev
NBG6716:
        Zyxel NBG 6716
        Packages: kmod-rtc-pcf8563 kmod-ath10k

如果不需要更改配置,直接就可以创建image了

1
make image PROFILE=WNDR4300

增加/修改配置

针对预编译包文件ar71xx的配置被放在target/linux/ar71xx/nand/profiles中。
编辑netgear.mk,将需要的包添加进去.

1
vi target/linux/ar71xx/nand/profiles/netgear.mk

#改为（将ubi和firmware增加96M，完全使用128M flash）

wndr4300_mtdlayout=mtdparts=ar934x-nfc:256k(u-boot)ro,256k(u-boot-env)ro,256k(caldata),512k(pot),2048k(language),512k(config),3072k(traffic_meter),2048k(kernel),121856k(ubi),123904k@0x6c0000(firmware),256k(caldata_backup),-(reserved)

文件

一个包含自定义文件的想要加入的目录可以通过使用FILES变量来指定，如果有必要的话自定义文件会替换掉默认已经存在的文件。
