# Build openwrt for raspberry pi zero w

Host machine:Ubuntu 18.04
Target machine:raspberry pi zero w

git clone https://git.openwrt.org/openwrt/openwrt.git
cd openwrt
./scripts/feeds update -a
./scripts/feeds install -a
make menuconfig
make V=99

menuconfig的配置參照**資料一**

---
最後會在**bin/targets/bcm27xx/bcm2708**底下找到四個image壓縮檔
* openwrt-bcm27xx-bcm2708-rpi-ext4-factory.img.gz
* openwrt-bcm27xx-bcm2708-rpi-ext4-sysupgrade.img.gz
* openwrt-bcm27xx-bcm2708-rpi-squashfs-factory.img.gz
* openwrt-bcm27xx-bcm2708-rpi-squashfs-sysupgrade.img.gz

之後藉由指令**dd**寫到sd card裡面。
