1 Introduction
- Note: the following method applies to NanoPi M2 too。
NanoPi 2 Fire使用的固件跟NanoPi 2通用，为了不跟NanoPi 2的SD WiFi产生冲突，内核缺省不编译USB WiFi。如果需要给NanoPi 2 Fire使用USB WiFi，可单独把USB WiFi编译进内核。
由于市面上USB WiFi型号多达上百种，如果把全部USB WiFi驱动选上不太现实，所以这里只介绍一种的方法，其他USB WiFi型号 方法一样，可参看此处自行编译支持。
- 示例USB WiFi芯片：RT3070；
- 无线标准： - IEEE 802.11b/g/n；
- 操作系统：Debian；
- 开始之前，需要先根据NanoPi 2 Fire的wiki：NanoPi_2_Fire，把启动卡做好。
2 Download Kernel Source Code
Please download the NanoPi 2 Fire's kernel source code:
git clone https://github.com/friendlyarm/linux-3.4.y.git cd linux-3.4.y git checkout nanopi2-lollipop-mr1
The NanoPi 2 Fire's kernel source code lies in the "nanopi2-lollipop-mr1" branch
3 Add USB WiFi in Menuconfig
Add the WIFI support in the kernel and compile
touch .scmversion make nanopi2_linux_defconfig make menuconfig [*] Networking support --> -*- Wireless --> [*] Generic IEEE 802.11 Networking Stack (mac80211) Device Drivers --> [*] Network device support --> [*] Wireless LAN --> [*] Ralink driver support --> [*] Ralink rt27xx/rt28xx/rt30xx (USB) support [*] rt2800usb - Include support for rt33xx devices [*] rt2800usb - Include support for rt35xx devices make uImage
After your compilation succeeds a uImage will be generated in the "arch/arm/boot/uImage" directory. You can use it to replace the existing uImage.hdmi.
syncIf you want to generate a kernel for LCD you can do it this way:
touch .scmversion make menuconfig Device Drivers --> Graphics support --> Nexell Graphics --> [*] LCD [ ] HDMI mak uImage
After your compilation succeeds a uImage will be generated for LCD. You can use it to replace the existing uImage.
4 下载linux-firmware
将SD卡插入开发板，并接上网线，然后上电，执行以下步骤安装RT3070的固件：
apt-get update apt-get install firmware-ralink
如果你使用的USB WiFi不是RT3070，你可以尝试安装所有固件即可：
apt-get install firmware-*
安装成功后，接上USB WiFi，板子即能识别到USB WiFi。
