      板子做工精致很有份量，拿在手里沉甸甸的，各种接口一应俱全——USB、TF 卡座、SIM卡座、4G模块卡座、网口、RGB LCD接口、LVDS、RS485、CAN、各种音频口、TV-in/TV-Out，板上还自带一个RTL8723du wifi/蓝牙二合一模块，作为一块主打工业控制的主控板这些接口实属绰绰有余了。手里的板子是256MB内存+256MB nand flash版本（这个是低配版本，还有个512MB+8GB emmc的高配版本），飞凌开发文档中提到已经移植好了Qt5开发环境，所以这个内存跑跑Qt的UI程序是再合适不过了，可惜手里没有匹配的开箱即用的LCD显示屏不然接上直接能试试出厂自带的Qt测试程序了。

      提供的开发资料中已经包含有Ubuntu 20.04 的虚拟机文件，因为是直接用的Linux版本系统，所以需要自己搭建开发环境，以下所涉内容都是在装有Ubuntu 20.04的PC上进行操作，而且，因为以前在安装过T113-S3的开发环境，所以在编译SDK过程中并没有碰到其他因缺少依赖软件报的错误。

      解压sdk

      cat OK113i-linux-sdk.tar.bz2* | tar jx -C ~/Dev/sdk/T113-i/

      编译前的准备

      除了 gcc，ncurse，bison，autoconf，wget，patch，texinfo，zlib，dos2unix 之外需要安装如下：

      sudo apt-get install git
sudo apt-get install gnupg

sudo apt-get install bison
sudo apt-get install gperf
sudo apt-get install build-essential
sudo apt-get install zip

      python 报系统库语法错误，根据经验是系统python版本问题，首先查看系统中python版本号

      python --version
Python 3.8.10

      不出意外的话编译系统依赖python 2.7，所以切换到python 2.7版本，具体操作如下：
      首先，查看系统有几个python版本

      update-alternatives --list python
/usr/bin/python2
/usr/bin/python3

      然后，通过如下切换到想要的版本

      update-alternatives --config python
There are 2 choices for the alternative python (providing /usr/bin/python).
 
  Selection    Path              Priority   Status
------------------------------------------------------------
* 0            /usr/bin/python3   2         auto mode

  2            /usr/bin/python3   2         manual mode
 
Press <enter> to keep the current choice[*], or type selection number: 1

      切换后，再确认python 版本：

      python --version
Python 2.7.18

      最后再试一次：

      ./build.sh config

      内核编译完后OK113i-linux-sdk/out目录需要注意，这个是所有的编译输出目录，后面buildroot编译完也是在这个目录编译输出的。此目录中如下几个目录需要特别记住：

      1. 编译内核的交叉编译工具链
        在 OK113i-linux-sdk/out/gcc-linaro-5.3.1-2016.05-x86_64_arm-linux-gnueabi目录下就是编译内核的交叉编译工具链。
      2. buildroot的交叉编译工具链
        在OK113i-linux-sdk/out/t113_i/ok113i/longan/buildroot/host/bin/中 arm-linux-gnueabi-g++等，编译应用程序的时候使用这个编译工具。
      3. 内核编译输出目录
        在OK113i-linux-sdk/out/kernel目录下就是内核编译目录位置，具体结构如下所示：
      ├── build # 编译生成的临时文件
│   ├── arch
│   ├── block
│   ├── certs
│   ├── crypto
│   ├── drivers #编译生成的驱动模块在此目录中
│   ├── fs
│   ├── include
│   ├── init
│   ├── ipc
│   ├── kernel
│   ├── lib
│   ├── Makefile
│   ├── mm
│   ├── modules.builtin
│   ├── modules.builtin.modinfo
│   ├── modules.order
│   ├── Module.symvers
│   ├── net
│   ├── scripts
│   ├── security
│   ├── sound
│   ├── source -> /home/luoyang/Dev/sdk/T113-i/OK113i-linux-sdk/kernel/linux-5.4
│   ├── System.map
│   ├── usr
│   ├── virt
│   ├── vmlinux
│   └── vmlinux.o
└── staging
    └── sunxi.dtb #猜测是设备树

      比如内核编译后wifi模块的驱动文件就存放在OK113i-linux-sdk/out/kernel/build/drivers/net/wireless/rtl8723du目录下的8723du.ko

      kernel menuconfig 配置

      build.sh menuconfig

      上面设置的config居然是out目录下的文件，重新编译会被覆盖。
      编译阶段打印使用这个配置/home/luoyang/Dev/sdk/T113-i/OK113i-linux-sdk/kernel/linux-5.4/arch/arm/configs/OK113I_linux_defconfig，试着改这个试试。

      buildroot 编译

      ./build.sh rootfs

      默认全部编译运行build.sh，会有如下打印有用信息，此处记录下：

      最后总结

      板子出厂的rootfs中包含的基础软件是真的很全面，基本可以做到开箱即用了，wifi驱动也已经适配了，wpa_supplicant、bluealsa、bluez、alsa、tinyalsa等工具软件也已经包含。因为目前手头没有能直接可用的显示屏，所以HMI显示和视频解码等高级功能没法体验。不过对于喜欢折腾的先适配一块触摸显示屏还是很有必要的，这样可玩性更高。
