【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：https://file1.elecfans.com/web2/M00/88/C3/wKgZomRwtmaAa7nJAAPbMXYiRMk471.png
在这对话框中输入想要保存的目录：
https://file1.elecfans.com/web2/M00/88/C2/wKgaomRwtt-AagDXAAO7329iUIw874.png
在下面的对话框中输入Y:
然后稍等安装完毕：Extracting SDK.......................................................................................................................................................................................................done
Setting it up...done
SDK has been successfully set up and is ready to be used.
Each time you wish to use the SDK in a new shell session, you need to source the environment setup script e.g.
$ . /opt/yg2lx/environment-setup-aarch64-poky-linux
$ . /opt/yg2lx/environment-setup-armv7vet2hf-neon-vfpv4-pokymllib32-linux-gnueabi
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：lugl@lugl-virtual-machine:~/MYD/sdk$ source /opt/yg2lx/environment-setup-aarch64-poky-linux
lugl@lugl-virtual-machine:~/MYD/sdk$ $CC -v
Using built-in specs.

到此，SDK就安装成功了。测试用vim编写一个hello.c:https://file1.elecfans.com/web2/M00/88/C3/wKgZomRwuZ2ABoZQAAG-TAiJ0mQ508.png
保存后编译：$CC hello.c -o hello编译后查看hello文件类型：lugl@lugl-virtual-machine:~/MYD/sdk$ file hello
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=5aa9a4ba2a1ff9ca3ef36c5d5508eb448b8f85f1, with debug_info, not stripped
上传到开发板，修改权限后执行：
https://file1.elecfans.com/web2/M00/88/C3/wKgZomRwvCGAC3vqAAA4cgERXEE989.png
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：

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 casy99 发表于 2023-7-8 08:37

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。
