1. 首先我们去官网下载需要的文件,我的板子是绿色板子.
  2. 我们找到官网,进入其中的资源下载

我们下载以下文件: 下载 还要下载烧录软件! 下载

安装交叉编译器

之前我们下载了RISC-V 64bit toolchain for Kendryte K210_win32交叉编译器。现在我们首先需要对他进行安装。

  1. 解压Toolchain

    我将交叉编译器放到了I:\Kendryte210\kendryte-toolchain.

  2. 设置环境变量

    打开系统的环境变量并将添加如下: 下载

开始编译

  1. 首先解压sdk

    我把sdk解压到了I:\Kendryte210\kendryte-standalone-sdk-0.5.0

  2. 安装Cmake

    我们要编译,首先得安装Cmake.去cmake官网下载安装.如果网速不给力可以去这里下载. 记得按照时选择添加到系统路径

  3. 生成Makefile

    在sdk中打开终端powershell运行： 

    PS I:\Kendryte210\kendryte-standalone-sdk-0.5.0> mkdir build


        目录: I:\Kendryte210\kendryte-standalone-sdk-0.5.0

    可以看到build下已经有几个文件生成. 配置成功

  4. 编译工程

    依旧是在那个目录下，执行mingw32-make命令。

    现在程序就被编译了出来.

烧录程序

此芯片暂时我只看到通过串口烧录程序的.我先解压下的K-Flash-V0.3.0到文件夹中. 运行如下(选择好串口通道和波特率以及二进制文件): 下载程序

提示 如果是黑色板子，那么没有问题，但是我这个是绿色板子初代版本，自动下载电路没有完善，所以需要手动拉低boot。 我们需要将IO16的跳线帽拔掉，并且在靠近芯片那一端接一根线出来连接到GND，然后按一下RESET！！，进入isp模式，才可以下载程序。 如图所示(最终我是在115200下载成功)： 下载成功

运行效果

现在我们打开串口调试助手，重启板子，就可以看到串口输出啦～～ 效果
