QSDK - QCA Software Development Kits, 基于 openwrt 加入了 QCA 相关的代码库，可以用于使用 qualcomm 芯片的路由器固件开发。本文讲述如何获取 QSDK.

我们通常会使用 git clone 获取开源项目的代码，比如 github, gitlab, coding 等平台，但是 QSDK 并不存放于这些平台，而是有它自己的维护站点，并且需要通过 repo 和 git 共同完成仓库文件的 clone, 下面来看看吧。

install repo

首先来安装 repo 工具，这其实是个 Python 脚本.

1

3
curl https://storage.googleapis.com/git-repo-downloads/repo -o repo
chmod +x repo
mv repo ~/bin/

也可以手动下载：https://gerrit.googlesource.com/git-repo/

install qsdk

下载完 repo 后，在 git 已经安装并配置好了基本的 email, username 的情况下就可以开始下载 QSDK 了。

不同型号的芯片对应不同的 manifest 文件，这是一个 xml 文件，有点类似 Android 开发的 mainfest.xml.

关于 QSDK 的 manifest, 可以参考下表，源自 https://wiki.codeaurora.org/xwiki/bin/viewrev/QSDK/WebHome?rev=13.1

OpenWrt Version Kernel Version SoC's Latest Available Release Branch Example Version Notes
15.05 3.14 ipq806x,ipq40xx caf_AU_LINUX_QSDK_NHSS.QSDK.6.1.0.R1_TARGET_ALL.0.1.2028.020.xml with uClibc

使用 repo 尝试下载：

$ repo init -u git://source.codeaurora.org/quic/cc-qrdk/releases/manifest/qstak -b release -m caf_AU_LINUX_QSDK_NHSS.QSDK.11.0_TARGET_ALL.11.0.3821.3949.xml
Downloading Repo source from https://gerrit.googlesource.com/git-repo
fatal: Cannot get https://gerrit.googlesource.com/git-repo/clone.bundle
fatal: error Tunnel connection failed: 502 Parent proxy unreacheable

fail 了，这是 Google 网络被墙的问题，为此我通过 v2ray + proxychians4 代理解决了。

  • v2ray: 订阅配置，需要梯子，可以网上自行搜索免费的，或者自行购买搭建。
  • proxychains4：可以方便配置 socks5 网络代理，配置说明参考 proxychains4.

在linux系统下，可以使用 Qv2ray 替代 V2rayN, 但是都需要安装 v2ray-core 的支持。关于 Qv2ray 可以参考

方便起见，可以在 .zshrc 或者 .bashrc 中添加一个 proxychains4 的 alias.

1
alias supro="sudo proxychains4"

网络代理不是本文重点，其目的是保证可以正常访问谷歌网络。下面使用 repo 进行 QSDK 的下载。

1
2
supro ~/bin/repo init -u git://codeaurora.org/quic/qsdk/releases/manifest/qstak -b release -m caf_AU_LINUX_QSDK_NHSS.QSDK.11.0_TARGET_ALL.11.0.3821.3949.xml
supro ~/bin/repo sync

下载速度依网络情况而定，毕竟用的代理，访问的是 Google， 所以速度你懂的。而且 sync 数据量非常大，所以下载时间会非常非常非常长。。。先去干别的吧。

总算下载完了，来看看根目录有哪些东西。

看起来确实和 openwrt 的目录结构挺像的。不过多了两个 wireshark 相关的目录。

关于 QSDK 的下载就讲完了，这里再说明下编译需要一些依赖工具，比如下面这些。

  • ocaml-nox: Objective Caml compiler for GUI of make menuconfig
  • zlib1g-dev: for zlib
  • libssl-dev: for openssl
  • subversion: for svn

具体编译相关的后续再说。
