qsdk编译

QSDK是一种在openwrt的基础上，加入了高通atheros芯片相关资料的一种环境。

QSDK与openwrt的区别主要在如下几个方面：

• arch/mips/ath79/* – updated QCA base platform device support – GPLv2
• sound/soc/ath79/* – new ALSA-compliant QCA soundcard driver – ISC
• drivers/net/ethernet/atheros/ag71xx/* – updated QCA Ethernet switch driver – GPLv2
• net/core/* – performance enhancement updates to Linux sk_buff management – GPL v2
• drivers/spi – added modes to QCA spi driver – GPLv2
• drivers/mtd/nand/ – new QCA NAND flash controller driver – ISC

编译步骤如下：（基于debian服务器）

1、安装开发所需软件：

     sudo apt-get install gcc g++ binutils ptach bzip2 flex make gettext pkg-config unzip zlib1g-dev libc6-dev subversion libncurses5-dev

      gawk sharutils curl libxml-parser-perl ocaml-nox

2、安装repo和git

      见  http://www.cnblogs.com/rohens-hbg/p/4916452.html

3、下载qsdk相关文件

        1) repo init -u git://codeaurora.org/quic/qsdk/releases/manifest/qstak -b release

                -m  caf_AU_LINUX_QSDK_RELEASE_BANANA_SW_TARGET_ALL.2.7.029.xml

        2) repo sync

        3) mkdir -p qsdk/dl

        4) tar xjvf qsdk-qca-wifi-2.7.029.tar.bz2 -C qsdk

            tar xjvf qsdk-qca-wlan-2.7.029.tar.bz2 -C qsdk

            tar xjvf qsdk-qca-shortcut-fe-2.7.029.tar.bz2 -c qsdk

   4、编译

        1)  cd qsdk

              make package/symlinks

        2)  拷贝配置文件，目前该目录下有三个配置文件

              ar71xx_open.config 

              ar71xx_premium.config  ： 生成16m flash使用的bin文件

              ar71xx_wireless.config ： 生成8m flash使用的bin文件

             cp qca/configs/qca955x.ln/ar71xx_<profile>.config .config

        3)  重新生成配置文件并build

              make defconfig

              make V=s

        4) 去目录下去.bin文件download到设备上

            目录路径为：qsdkinar71xx

            主要文件为：openwrt-ar71xx-generic-ap147-16M-kernel.bin  (或  openwrt-ar71xx-generic-ap147-16M-kernel.bin)

                             openwrt-ar71xx-generic-ap147-16M-rootfs-squashfs.bin (或 openwrt-ar71xx-generic-ap147-8M-rootfs-squashfs.bin)
