MYZR-A40I-EK204 Linux-3.10.65 编译参考手册

源码包的下载需到我们提供的网盘上来进行下载 。下载到电脑后，

需要通过Samba或其他方法将其复制到虚拟机上来。

​ 我们可以创建一个A40I专属的目录来存放相关的源码，编译工具和以后用到的一些东

西。如我的目录为：/home/liangyh/my-work/A40I，在此目录下我又创建了4个子目录：

=====> Input:
liangyh@FS12:~/my-work/A40I$ ls
01_image 02_sources 03_toolchain 04_app

​ 01目录可以用来放置我们编译好的镜像（以后用到会说明）

​ 02目录则是用来放置源码

​ 03目录则是放置交叉编译工具配置脚本

​ 04目录我们可以用来放置自己的应用（用户自己分配）

​ 使用Samba或其他方法将源码包复制到虚拟机中的~/my-work/A40I/02_sources目录

下后将源码包解压到当前目录下：

=====> Input:
~/my-work/A40I/02_sources$ cat repo_A40I.tar.bz2a* | tar xjv

创建交叉编译工具配置脚本

=====> 输入指令：
cat << EOF > ~/my-work/A40I/03_toolchain/arm-openwrt-linux-muslgnueabi.sh
#!/bin/sh
export PATH=${HOME}/my-work/A40I/02_sources/repo_A40I/prebuilt/gcc/linux-x86/arm/toolchain-sunxi-musl/toolchain/bin/:${PATH}
export ARCH=arm
export CROSS_COMPILE=${HOME}/my-work/A40I/02_sources/repo_A40I/prebuilt/gcc/linux-x86/arm/toolchain-sunxi-musl/toolchain/bin/arm-openwrt-linux-muslgnueabi-
export CC=${HOME}/my-work/A40I/02_sources/repo_A40I/prebuilt/gcc/linux-x86/arm/toolchain-sunxi-musl/toolchain/bin/arm-openwrt-linux-muslgnueabi-gcc
EOF

获取可执行权限

chmod +x ~/my-work/A40I/03_toolchain/arm-openwrt-linux-muslgnueabi.sh

tina 源码编译

源码使用脚本编译，自动配置交叉编译工具，编译源码，最后打包生成板子 img 镜像文件。

1. 设置环境

=====> Input:
$ sudo apt-get install libssl-dev
$ sudo apt-get install gperf
$ sudo apt-get install lib32stdc++6

=====> Input:
$ source build/envsetup.sh

=====> Output:
Setup env done! Please run lunch next.

1. 设置编译平台

=====> Input:
$ lunch r40_m2ultra-tina

=====> Output:
============================================
TINA_BUILD_TOP=/home/liangyh/my-work/A40I/02_sources/repo_A40I
TINA_TARGET_ARCH=arm
TARGET_PRODUCT=r40_m2ultra
TARGET_PLATFORM=r40
TARGET_BOARD=r40-m2ultra
TARGET_PLAN=m2ultra
TARGET_BUILD_VARIANT=tina
TARGET_BUILD_TYPE=release
TARGET_KERNEL_VERSION=3.10
TARGET_UBOOT=u-boot-2014.07
TARGET_CHIP=sun8iw11p1
============================================

1. 编译uboot

=====> Input:
$ muboot

4.编译kernel

=====> Input:
$ make 

=====> Output:
Checking 'working-make'... ok.
Checking 'case-sensitive-fs'... ok.
Checking 'gcc'... ok.
Checking 'working-gcc'... ok.

......

#### make completed successfully (23:30 (mm:ss)) ####

5.打包固件

=====> Input:
$ pack

=====> Output:
No kernel param, parse it from r40
copying tools file
copying configs file

......

/home/liangyh/my-work/A40I/02_sources/repo_A40I/out/r40-m2ultra/tina_r40-m2ultra_uart0.img

pack finish

生成固件地址：

repo_A40I/out/r40-m2ultra/tina_r40-m2ultra_uart0.img

应用编程示例

使用Samba或其他方法将源码包复制到虚拟机中的~/my-work/A40I/04_app目录下。

1. 配置交叉编译工具

=====> Input:
$ source ~/my-work/A40I/03_toolchain/arm-openwrt-linux-muslgnueabi.sh 

2. 检验交叉编译工具配置

=====> Input:
$CC -v

=====> Output:

3. 开始编译

=====> Input:
${CC} hello_world.c -o hello_world

4. 执行

将编译出的二进制文件hello_world移动到开发板（移动方法参考前面体验篇的文件传输）。

给予可执行权限并执行文件

=====> Input:
# chmod +x hello_world
# ./hello_world

=====> Output:
hello world!!!

成功运行后成功输出 hello world 的信息。
