编译 AR9271 wifi 网卡固件 htc_9271.fw

下载最新的固件源码
https://github.com/qca/open-ath9k-htc-firmware/archive/1.4.0.zip
得到 open-ath9k-htc-firmware-1.4.0.zip 解压 也可以直接  clone 项目 git clone https://github.com/qca/open-ath9k-htc-firmware.git

编译方法
How do I build it?
------------------
You're in for a treat.
* Install the cmake build tool (http://www.cmake.org/).
  Major distributions have packages for this.
* For FreeBSD - install gmake and wget.
* You first have to build the toolchain.
  * Linux:
  $ make toolchain
  * FreeBSD:
  $ gmake toolchain
  (Yes, I made this work on FreeBSD as well.)
* Next, build the firmware.
  * Linux:
  $ make -C target_firmware
  * FreeBSD:
  $ gmake -C target_firmware
You will end up with two .fw files - one for the AR7010 and one for
the AR9271 in the target_firmware directory.

手猾了一下，打了一个 make
然后等了半个小时，又是下载，又是安装的，没用管它。

安装 cmake
apt-get install cmake 安装不上，使用编译安装，因为我之前是装过 mysql5.5

cmake 安装方法

先装 bison
tar zxvf bison-2.5.tar.gz
cd bison-2.5
./configure
make
make install

装 cmake
tar zxvf cmake-2.8.6.tar.gz
cd cmake-2.8.6
./bootstrap
make
make install

回到 open-ath9k-htc-firmware-1.4.0
make -C target_firmware

得到生成的固件
cp build/k2/htc_*.fw build/magpie/htc_*.fw .
make:离开目录“/home/open-ath9k-htc-firmware-1.4.0/target_firmware”
./target_firmware/htc_9271.fw

将 htc_9271.fw 上传到 ARM 开发板 lib/firmware/
