【米尔瑞萨RZ/G2L开发板-试用体验】安装交叉编译器

安装SDK

下载sdk并上传到虚拟机，解压后执行：

在这对话框中输入想要保存的目录：

在下面的对话框中输入Y:

然后稍等安装完毕：

1. Extracting SDK.......................................................................................................................................................................................................done
   
2. Setting it up...done
   
3. SDK has been successfully set up and is ready to be used.
   
4. Each time you wish to use the SDK in a new shell session, you need to source the environment setup script e.g.
   
5. $ . /opt/yg2lx/environment-setup-aarch64-poky-linux
   
6. $ . /opt/yg2lx/environment-setup-armv7vet2hf-neon-vfpv4-pokymllib32-linux-gnueabi

复制代码

测试SDK

安装完成后，使用以下命令设置环境变量，测试 SDK 是否完成：

1. lugl@lugl-virtual-machine:~/MYD/sdk$ source /opt/yg2lx/environment-setup-aarch64-poky-linux
   
2. 
   
3. lugl@lugl-virtual-machine:~/MYD/sdk$ $CC -v
   
4. Using built-in specs.
   
5. COLLECT_GCC=aarch64-poky-linux-gcc
   
6. COLLECT_LTO_WRAPPER=/opt/yg2lx/sysroots/x86_64-pokysdk-linux/usr/libexec/aarch64-poky-linux/gcc/aarch64-poky-linux/8.3.0/lto-wrapper
   
7. Target: aarch64-poky-linux
   
8.

9. Thread model: posix
   
10. gcc version 8.3.0 (GCC)

复制代码

到此，SDK就安装成功了。

测试

用vim编写一个hello.c:

保存后编译：$CC hello.c -o hello

编译后查看hello文件类型：

1. lugl@lugl-virtual-machine:~/MYD/sdk$ file hello
   
2. hello: ELF 64-bit LSB shared object, ARM aarch64, version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linux-aarch64.so.1, for GNU/Linux 3.14.0, BuildID[sha1]=5aa9a4ba2a1ff9ca3ef36c5d5508eb448b8f85f1, with debug_info, not stripped

复制代码

上传到开发板，修改权限后执行：

成功的输出了hello world，说明SDK安装成功！

官方的SDK在哪下载呀？

这是安装Toolchain吧，基于Yocto的SDK在哪里下载呢？

我按照MYD-YG2LX_Linux软件开发指南.pdf从github拉的代码只有这么点东西：

bash: /home/cambricon/work/Rcar/myir-renesas-yocto/layers/poky/oe-init-build-env: No such file or directory

myir-environment.sh 脚本会调oe-init-build-env，但是poky里是空的。难道需要自己加poky吗？

好吧，还得用打包好的yocto压缩包，github的不完整

您拿到板子里面操作指南有的呢

一看，还是我写的文章呀，楼主没有给我签名呀。
