QSDK与OPENWRT区别

来源 https://www.jianshu.com/p/178ae18b2570

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ubuntu）

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

安装repo和git
见前篇

下载：

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

```
 repo sync
```
```
mkdir -p qsdk/dl
```

   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

编译QSDK

     cd qsdk
      make package/symlinks

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

重新生成配置文件并build
```
make defconfig
```
make V=s
去目录下去.bin文件download到设备上

目录路径为：qsdk\bin\ar71xx
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)
