# 芯来科技RVSTAR开发板 #
## 简介
**RVSTAR开发板** 是由芯来科技公司推出的基于采用芯来科技RISC-V架构处理器芯片的GD32VF103的开发板。
更多关于 **RVSTAR开发板** 开发板的详细资料请参见 [RVSTAR开发板快速入门](https://www.rvmcu.com/quickstart-quickstart-index-u-RV_STAR.html)
### 板载资源
| 硬件 | 描述 |
| --- | --- |
| 内核 | Nuclei N205 |
| 架构 | 32-bit RV32IMAC |
| 主频 | 108 MHz |
## 工具安装
### 安装工具链
请根据[安装Nuclei RISC-V GCC Toolchain和OpenOCD](https://doc.nucleisys.com/nuclei_sdk/quickstart.html#setup-tools-and-environment) 来安装依赖的工具。
### 添加环境变量
将Nuclei RISC-V GCC Toolchain和OpenOCD的环境变量进行设置。
#### Windows
假设工具安装在 **D:\Software\Nuclei**目录下, 则可以修改系统环境变量**PATH**,
将**D:\Software\Nuclei\gcc\bin;D:\Software\Nuclei\openocd\bin;**增加到**PATH**中。
或者在ENV工具命令行中运行
~~~cmd
set PATH=D:\Software\Nuclei\gcc\bin;D:\Software\Nuclei\openocd\bin;%PATH%
~~~
#### Linux
假设工具安装在 **~/Software/Nuclei**目录下, 通过在Linux的``.bashrc``增加如下一行代码
来添加环境变量。
~~~bash
export PATH=~/Software/Nuclei/gcc/bin:~/Software/Nuclei/openocd/bin:$PATH
~~~
或者在ENV工具命令行中运行
~~~bash
export PATH=~/Software/Nuclei/gcc/bin:~/Software/Nuclei/openocd/bin:$PATH
~~~
**注意**: 对应的RISC-V GCC和OPENOCD的路径请替换成自己安装的路径。
## 烧写及执行
### [驱动设置](https://doc.nucleisys.com/nuclei_board_labs/hw/hw.html#on-board-debugger-driver)
### 编译程序
下载好[RT-Thread](https://github.com/RT-Thread/rt-thread)的代码和[ENV工具](https://www.rt-thread.org/document/site/tutorial/env-video/)以后。
按照ENV工具的教程, 在**rt-thread\bsp\nuclei\gd32vf103_rvstar**目录打开ENV工具命令行。
**注意**: 请确保Nuclei GCC和Nuclei OpenOCD的路径设置正确无误。
1. 运行 ``pkgs --update``来下载最新的依赖的**Nuclei SDK**开发包
2. **可选**: 运行 ``menuconfig``来进行内核配置
3. 运行 ``scons -c``清理之前的编译结果
4. 运行 ``scons``来进行代码的编译
### 下载程序
在保证程序能够正常编译后, 在相同ENV终端执行``scons --run upload``进行代码的下载。
正常下载的输出如下:
~~~

下载程序之后, 连接串口(115200-N-8-1), 可以看到 RT-Thread 的输出信息：
```

```
在串口终端(我这里使用的是TeraTerm)输入``ps``即可查看当前线程工作情况:
~~~

### 调试程序
在保证程序编译成功后, 在相同ENV终端执行``scons --run debug``进行代码在命令行下进行GDB调试。
正常的调试输出如下：

为了更方便的进行调试, 也可以下载**Nuclei Studio**集成开发环境, 创建一个Debug Configuration, 选择编译好的
ELF文件, 然后配置OPENOCD和GDB即可, OPENOCD配置文件路径为**bsp\nuclei\gd32vf103_rvstar\packages\nuclei_sdk-latest\SoC\gd32vf103\Board\gd32vf103v_rvstar\openocd_gd32vf103.cfg**
## 驱动支持情况
| 驱动 | 支持情况 | 备注 |
| ------ | ---- | :------: |
| UART | 支持 | RV-STAR板载串口是UART4 |
**注:**
- 适配RT-Thread的驱动框架的代码在 [../libraries/gd32vf103/HAL_Drivers](../libraries/gd32vf103/HAL_Drivers)目录下。
- 如果有开发者想适配更多的驱动, 请在对应目录下增加驱动适配支持。
