在opt文件夹下建立一个名为SDK4320的文件夹，为的是方便以后增加其他包的时候不混将MediaTek_ApSoC_SDK_4320_20150414.tar.bz2包复制到opt下的SDK4320，使用#tar jxvf 命令进行解压/opt/SDK4320# tar jxvf MediaTek_ApSoC_SDK_4320_20150414.tar.bz2。
1、Install toolchain将buildroot‐gcc463_32bits.tar.bz2复制到opt下后，回到opt下使用tar jxvf进行解压 # cp RT288x_SDK/toolchain/buildroot‐gcc463_32bits.tar.bz2 /opt#tar jxvf buildroot‐gcc463_32bits.tar.bz2解压mips‐2012.03.tar.bz2到opt下# cp RT288x_SDK/toolchain/ mips‐2012.03.tar.bz2 /opt#tar jxvf mips‐2012.03.tar.bz22、install LZMA Utility进入到SDK4320/RT288x_SDK/toolchain/，解压lzma‐4.32.7.tar.gz进入到lzma‐4.32.7 下，输入下面的指令#./configure#make#make install3、install mksquashfs utilityMT7628使用的是2.6.36的内核，所以选择3.2版本进入toolchain/mksquash_lzma‐3.2，输入下面的指令#make#make install返回上一级 cd .. ，在toollchain下会看到squashfs4.2.tar.bz2，进行解压以下好像只有用到3.10.14的内核时才会用到，可以不理会，#tar jxvf squashfs4.2.tar.bz2#cd squashfs4.2/squashfs‐tool#make#cp mksquashfs/opt/buildroot‐gcc342/bin/mksquashfs_lzma‐4.24、配置Uboot平台进入到Uboot文件下，输入make menuconfig，如果是在root下，就直接输入，如果 不是在root下，就使用sudo make menuconfig。

This initializes all the tools in one step.1.Determine your installation directory,<install_dir>:a.If your compiler was installed in the default location by a root user or sudo user, the compiler willbe installed under/opt/intel/oneapi. In this case, <install_dir> is /opt/intel/oneapi.b.For non-root users, your home directory under intel/oneapi is used. In this case,<install_dir> will be $HOME/intel/oneapi.c.For cluster or enterprise users, your admin team may have installed the compilers on a sharednetwork file system. Check with your local admin staff for the location of installation(<install_dir>).2.Source the environment-setting script for your shell:a.bash: source <install_dir>/setvars.sh intel64b.csh/tcsh: source <install_dir>/setvars.csh intel64Install GPU Drivers or Plug-ins (Optional)You can develop oneAPI applications using C++ and SYCL* that will run on Intel, AMD*, or NVIDIA* GPUs. To develop and run applications for specific GPUs you must first install the corresponding drivers or plug-ins:•To use an Intel GPU, install the latest Intel GPU drivers.•To use an AMD GPU, install the oneAPI for AMD GPUs plugin from Codeplay.•To use an NVIDIA GPU, install the oneAPI for NVIDIA GPUs plugin from Codeplay.Option 1: Use the Command Line®4Get Started with the Intel® oneAPI DPC++/C++ Compiler 1Invoke the compiler using the following syntax:{compiler driver} [option] file1 [file2...]For example:icpx hello-world.cppFor SYCL compilation, use the -fsycl option with the C++ driver:icpx -fsycl hello-world.cppNOTE When using -fsycl, -fsycl-targets=spir64 is assumed unless the -fsycl-targets isexplicitly set in the command.51 Get Started with the Intel® oneAPI DPC++/C++ CompilerIf you are targeting an AMD or NVIDIA GPU, refer to the corresponding Codeplay plugin get started guide for detailed compilation instructions:•oneAPI for AMD GPUs Get Started Guide•oneAPI for NVIDIA GPUs Get Started GuideOption 2: Use the Eclipse* CDTFollow these steps to invoke the compiler from within the Eclipse* CDT.Install the Intel® Compiler Eclipse CDT plugin.1.Start Eclipse2.Select Help > Install New Software3.Select Add to open the Add Site dialog4.Select Archive, browse to the directory <install_dir>/compiler/<version>/linux/ide_support,select the .zip file that starts with piler, then select OK5.Select the options beginning with Intel, select Next, then follow the installation instructions6.When asked if you want to restart Eclipse*, select YesBuild a new project or open an existing project.1.Open Existing Project or Create New Project on Eclipse2.Right click on Project > Properties > C/C++ Build > Tool chain Editor3.Select Intel DPC++/C++ Compiler from the right panelSet build configurations.1.Open Existing Project on Eclipse2.Right click on Project > Properties > C/C++ Build > Settings3.Create or manage build configurations in the right panelBuild a Program From the Command LineUse the following steps to test your compiler installation and build a program.e a text editor to create a file called hello-world.cpp with the following contents:#include <iostream>int main(){std::cout << “Hello, world!\n”;return 0;}pile hello-world.cpp:icpx hello-world.cpp -o hello-worldThe -o option specifies the file name for the generated output.3.Now you have an executable called hello-world which can be run and will give immediate feedback: hello-worldWhich outputs:Hello, world!You can direct and control compilation with compiler options.

MT7681程序下载方式实例1.准备工作软件工具：SecureCRT烧写文件：MT7681 sta header.bin电脑USB转模块TTL串口线一条2 .下载步骤（仅供参考）1.）使用USB转TTL串口线连接电脑和模块，注意上电前只需连接模块的VCC GND和TXD三根有效线，切记要把串口线接正确。
不然可能会出现乱码。
2.）解压SecureCRT.zip文件夹，找到SecureCRT.exe并打开，设置后运行。
软件的设置主要在option菜单栏下设置。
其他的不用设置的，还有刚打开的时候背景颜色是黑色的（可能）这些是可以设置的。
刚开始的时候没有对话框，自己点击右下角，选择对话框，这样才可以发命令的。
然后可以鼠标停留在对话框的时候，可以拉动鼠标更改对话的大小。
最后新建一个连接如下: 点击快速连接或者（alt+q）出现如下对话框:注意画红色的部分，波特率，自己的串口号:3.）模块仅在开机4秒内处于Recovery模式，即受程序下载的模块，并且只能在此时间内接受升级指令。
所以建议操作前新建一个记事本文件准备好需要使用到的两条AT指令：AT#Reboot重启指令和AT#U pdateFW升级指令AlffQpdate™4.操作前确认SecureCRT软件能正确收到模块的串口输出的数据,为了保证快速有效的下载升级文件，请事先准备好需要下载的文件,建议复制到桌面文件夹（如复制到桌面MT7681_DOWNLOAD文件夹），方便查找下载。
这个根据个人习惯，找到最快找到文件的方法。
5.）下载文件准备妥当后，执行两步：首先发送AT#Reboot重启指令（发送区直接回车）（注意这个时候把按键按起，再发指令）让模块重新启动，然后在模块重启提示“ ==> Recovery Mode时迅速发送AT#U pdateFW升级指令，直到出现“ ccccC字符表示等待下载，实际操作截图如下:文如 Mm 直看湎述项口 件Km ■車冈 TAit) ，心辺D 打却-乙附3 葺痢t « -. 卜诂9 COM}负 Qg 了rhn\itk ］』』7 33 彌tbfl^asfcj4^/9S4a __ Sub^5ub-o &ub^44AJ9014492204j^9esoo4 5<M ；Se'4511055 ]4517?51 -4H3&4 945jyg0€5ul?=0Bub=m^uh=a 6. )模块进入等待下载模式后，选择“传输 -＞发送Xmodem ”列"，sub-oSH-0. : ■5^-1 . !HTdSkwraibcf 町曲riraskwraskSWT’i5*1=2 .:iSM 工I[臧慚则=> Recovery ”ode ccccam ■左槿肓世11。
