开发环境搭建
本章节将讲解如何在 ubuntu18.04.6 搭建 T113s3prov1.3 sdnand版本的开发环境。
获取Tina5.0-SDK源码
首先，在Windows上访问下面的论坛地址，打开Tina5-SDK基础包获取：tina5.0-sdk下载地址 。
通过百度网盘下载，大小约3.3G，名称为tina5sdk-bsp-50ae436fe556be2253856af283b1e094.tar.gz 下载完成后通过网络等方式拷贝到虚拟机目录下。
把基础包拷贝到虚拟机之后，执行以下指令，进行解压：
ubuntu@ubuntu1804:~$ tar -xvf tina5sdk-bsp-50ae436fe556be2253856af283b1e094.tar.gz
解压后，sdk基础包的命名是tina5sdk-bsp。
以上只是获取一个Tina5-SDK的一个基础包，并 不是完整 的SDK源码，还需要获取执行以下几步，才可以得到一个完整的Tina5-SDK源码包。
ubuntu@ubuntu1804:~$ cd tina5sdk-bsp/
ubuntu@ubuntu1804:~/tina5sdk-bsp$ git clone https://e.coding.net/weidongshan/tina5/buildroot.git
ubuntu@ubuntu1804:~/tina5sdk-bsp$ git clone https://e.coding.net/weidongshan/tina5/openwrt.git
ubuntu@ubuntu1804:~/tina5sdk-bsp$ git clone https://e.coding.net/weidongshan/tina5/platform.git
ubuntu@ubuntu1804:~/tina5sdk-bsp$ ls
brandy build buildroot build.sh device kernel openwrt platform prebuilt tools
ubuntu@ubuntu1804:~/tina5sdk-bsp$
出现以上文件，说明Tina5-SDK源码获取成功。
获取补丁包
在获取补丁包之前，先删除几个目录，
rm /home/ubuntu/tina5sdk-bsp/platform/allwinner/wireless/firmware/aic8800/aic8800d80/* -rf
rm /home/ubuntu/tina5sdk-bsp/kernel/linux-5.4/drivers/net/wireless/aic8800/ -rf
rm /home/ubuntu/tina5sdk-bsp/brandy/brandy-2.0/spl-pub/* -rf
基于T113s3pro v1.3 sdnand版本开发板，我们提供了一个扩展补丁包，执行以下指令，获取扩展支持仓库，然后加以应用，
ubuntu@ubuntu1804:~/tina5sdk-bsp$ cd ~/
ubuntu@ubuntu1804:~$ git clone https://github.com/DongshanPI/100ASK_T113s3-SdNand_TinaSDK5.git
ubuntu@ubuntu1804:~$ cd T113S3-PRO_TinaSDK5
ubuntu@ubuntu1804:~/T113S3-PRO_TinaSDK5$ git submodule update --init
ubuntu@ubuntu1804:~/T113S3-PRO_TinaSDK5$ cp ./* -rfvd ~/tina5sdk-bsp
编译固件
进入 sdk 源码根目录 tina5sdk-bsp ，执行以下指令，删除配置文件：
ubuntu@ubuntu1804:~$ cd tina5sdk-bsp/
ubuntu@ubuntu1804:~/tina5sdk-bsp$ rm .buildconfig
继续在当前路径下，执行指令，初始化环境变量，
ubuntu@ubuntu1804:~/tina5sdk-bsp$ source build/envsetup.sh
NOTE: The SDK(/home/ubuntu/tina5sdk-bsp) was successfully loaded
load openwrt... ok
Please run lunch next for openwrt.
load buildroot,bsp...ok
Invoke . build/quick.sh from your shell to add the following functions to your environment:
croot - Changes directory to the top of the tree
cbsp - Changes directory to the bsp
cbsptest - Changes directory to the bsptest
ckernel - Changes directory to the kernel
cbrandy - Changes directory to the brandy
cboot - Changes directory to the uboot
cbr - Changes directory to the buildroot
cchips - Changes directory to the board
cconfigs - Changes directory to the board's config
cbin - Changes directory to the board's bin
cdts - Changes directory to the kernel's dts
ckernelout - Changes directory to the kernel output
cout - Changes directory to the product's output
copenssl - Changes directory to the product's openssl-1.0.0
Usage: build.sh [args]
build.sh - default build all
build.sh bootloader - only build bootloader
build.sh kernel - only build kernel
build.sh buildroot_rootfs - only build buildroot
build.sh menuconfig - edit kernel menuconfig
build.sh saveconfig - save kernel menuconfig
build.sh recovery_menuconfig - edit recovery menuconfig
build.sh recovery_saveconfig - save recovery menuconfig
build.sh buildroot_menuconfig - edit buildroot menuconfig
build.sh buildroot_saveconfig - save buildroot menuconfig
build.sh clean - clean all
build.sh distclean - distclean all
build.sh pack - pack firmware
build.sh pack_debug - pack firmware with debug info output to card0
build.sh pack_secure - pack firmware with secureboot
Usage: pack [args]
pack - pack firmware
pack -d - pack firmware with debug info output to card0
pack -s - pack firmware with secureboot
pack -sd - pack firmware with secureboot and debug info output to card0
接着执行编译指令，首次编译需要我们选择相应的单板选项。如下：
ubuntu@ubuntu1804:~/tina5sdk-bsp$ ./build.sh

需要等待一段时间，编译完成后，在当前目录下，执行以下指令，进行镜像打包，
ubuntu@ubuntu1804:~/tina5sdk-bsp$ ./build.sh pack
镜像打包完成 后，执行 cout 会进入到镜像生成的路径。
