安裝SDK

下載sdk并上傳到虛擬機，解壓后執(zhí)行：

在這對話框中輸入想要保存的目錄：

在下面的對話框中輸入Y:

然后稍等安裝完畢：

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

測試SDK

安裝完成后，使用以下命令設(shè)置環(huán)境變量，測試 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

到此，SDK就安裝成功了。

測試

用vim編寫一個hello.c:

保存后編譯：$CC hello.c -o hello

編譯后查看hello文件類型：

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[sha1]=5aa9a4ba2a1ff9ca3ef36c5d5508eb448b8f85f1, with debug_info, not stripped

上傳到開發(fā)板，修改權(quán)限后執(zhí)行：

成功的輸出了hello world，說明SDK安裝成功！
