This SDK is for Kendryte K210 which contains FreeRTOS support.
If you have any questions, please be free to contact us.

## Usage

If you want to start a new project, for instance, `hello_world`, you only need to:

- Linux and OSX

`mkdir` your project in `src/`, `cd src && mkdir hello_world`, then put your codes in it, and build it.

```bash
mkdir build && cd build
cmake .. -DPROJ=<ProjectName> -DTOOLCHAIN=/opt/riscv-toolchain/bin && make
```

- Windows

Download and install latest CMake.

[Download cmake-3.14.1-win64-x64.msi](https://github.com/Kitware/CMake/releases/download/v3.14.1/cmake-3.14.1-win64-x64.msi)

Download and install latest toolchain.

[Download kendryte-toolchain-win-i386-8.2.0-20190409.tar.xz](https://github.com/kendryte/kendryte-gnu-toolchain/releases/download/v8.2.0-20190409/kendryte-toolchain-win-i386-8.2.0-20190409.tar.xz)

Open a Windows Powershell, cd to Project directory.

`mkdir` your project in `src/`, `cd src && mkdir hello_world`, then put your codes in it, and build it.

```powershell
$env:Path="E:\kendryte-toolchain\bin;C:\Program Files\CMak
e\bin" +  $env:Path

mkdir build && cd build
cmake -G "MinGW Makefiles" ../../../..
make
```

You will get 2 key files, `hello_world` and `hello_world.bin`.

1. If you are using JLink to run or debug your program, use `hello_world`
2. If you want to flash it in UOG, using `hello_world.bin`, then using flash-tool(s) burn <ProjectName>.bin to your flash.

This is very important, don't make a mistake in files.

*If you don't like place code inside SDK, see `CMakeLists.txt.example.cmake`*
