  • 复制设备树目标文件
=====> Input:
cp arch/arm/boot/dts/myimx6ek140p-6y-256m-emmc.dtb ./

编译内核模块包

  • 执行编译
=====> Input:
make modules

=====> Output: 
  CHK     include/config/kernel.release
  CHK     include/generated/uapi/linux/version.h
  ......
  LD [M]  sound/usb/snd-usb-audio.ko
  LD [M]  sound/usb/snd-usbmidi-lib.ko
  • 创建内核模块的保存目录
=====> Input:
mkdir modules
  • 安装内核模块到指定目录
=====> Input:
make modules_install INSTALL_MOD_PATH=./modules

=====> Output: 
  INSTALL crypto/echainiv.ko
  INSTALL crypto/tcrypt.ko
  ......
  INSTALL sound/usb/snd-usb-audio.ko

Linux C程序编译

准备源码

  打开网盘到 5_MY-Demo -> MY-Linux-C-Demo,下载 hello.c 文件,并复制到虚拟机。

编译目标文件

=====> Input:
$CC hello.c -o hello.out

Note: 如果有“未找到命令”的信息,是因为交叉编译工具链的配置没有生效,可以按前面 “交叉编译工具链安装” 中的 “source 工具链配置文件” 操作一次后再执行此步骤

运行Linux C目标程序

  • 把编译得到的 hello.out 复制到开发板上
  • 在开发板上运行Linux C目标程序
=====> Input:
chmod +x ./hello.out
./hello.out

=====> Output:

Linux QT5程序编译

准备源码

  打开网盘到 5_MY-Demo,下载 MY-Linux-QT5-Demo-AboutUs-svn*.tar.bz2 文件,并复制到虚拟机。

  • 解压源码包到工作目录
=====> Input:
tar xf MY-Linux-QT5-Demo-AboutUs-svn*.tar.bz2 -C ~/my-work/02_source/

QT程序编译

  • 进入源码目录
=====> Input:
cd ~/my-work/02_source/AboutUs/
  • 生成Makefile文件
=====> Input:
qmake

=====> Output: 
Info: creating stash file /home/myzr/my-work/02_source/AboutUs/.qmake.stash

Note: 如果有“未找到 'qamke' 命令”的信息,是因为交叉编译工具链的配置没有生效,可以按前面 “交叉编译工具链安装” 中的 “source 工具链配置文件” 操作一次后再执行此步骤

  • 编译目标文件
=====> Input:
make

=====> Output:

在 MY-IMX6-A9 设备上运行

  • 把编译得到的 AboutUs 复制到开发板上
  • 在开发板上运行QT5目标程序
=====> Input:
chmod +x ./AboutUs
./AboutUs -platform eglfs

在 MY-IMX6-A7 设备上运行

  • 把编译得到的 AboutUs 复制到开发板上
  • 在开发板上运行QT5目标程序
=====> Input:
export DISPLAY=:0.0
chmod +x AboutUs
./AboutUs

运行结果

可以看到开发板显示屏上输出了 MYZR 的 Logo 和一些信息。
