|
||
|
||
## 简介
|
||
|
||
**RVSTAR开发板** 是由[芯来科技Nuclei](https://nucleisys.com/)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-doc-u-rvstar.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,修改链接脚本。
|
||
|
||
```c
|
||
.stack ORIGIN(RAM) + LENGTH(RAM) - __TOT_STACK_SIZE (NOLOAD) :
|
||
{
|
||
...
|
||
PROVIDE( _sp = . );
|
||
PROVIDE( __rt_rvstack = . );//在链接脚本中补充该条语句
|
||
} >RAM AT>RAM
|
||
```
|
||
|
||
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:
|
||
|
||
~~~bat

#### 命令行GDB调试
|
||
|
||
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：
|
||
|
||

||
#### Nuclei Studio IDE调试
|
||
|
||
为了更方便的进行图形化调试, 也可以下载并使用[**Nuclei Studio IDE**](https://nucleisys.com/download.php)集成开发环境.
|
||
|
||
1. 打开Nuclei Studio IDE, 创建一个名为**Nuclei_RT-Thread**的**C Project**，Project Type选择**Empty Project**,
|
||
Toolchain选择**RISC-V Cross GCC**, 然后点击**Finish**.
|
||
|
||
|
||
|
||
2. 选中**rt-thread**的代码目录，然后鼠标左键拖到Nuclei Studio中创建好的**Nuclei_RT-Thread**工程中，选择
|
||
**Link to files and folders**, 点击**OK**, 就将**rt-thread**的代码拖到了工程中并创建软链接，注意这里建立的工程
|
||
仅用于调试，不可以用于编译，编译请使用上文中提到的`scons`命令。
|
||
|
||
|
||
|
||
3. 创建一个OpenOCD Debugging Configuration, 选择编译好的ELF文件, 并选定**Disable auto build**, 如下图所示:
|
||
|
||
|
||
|
||
4. 然后打开**Debugger**Tab, 配置好OPENOCD的配置文件路径, 其中OPENOCD配置文件路径为
|
||
*bsp\nuclei\gd32vf103_rvstar\packages\nuclei_sdk-latest\SoC\gd32vf103\Board\gd32vf103v_rvstar\openocd_gd32vf103.cfg*，
|
||
请在配置时使用完整绝对路径，根据自己文件所在目录来提供。配置完毕后，点击 **Debug**，开始下载调试。
|
||
|
||
|
||
|
||
5. 最终调试界面如下所示
|
||
|
||
|
||
|
||
6. 上面步骤中的路径请根据自己的环境进行调整，调试时请确保开发板正常连接到电脑，并且调试器驱动安装正确。
|
||
|
||

|
||
### 适配开发板Pinmux
|
||
|
||
如果需要使用到其他的外设驱动，则首先需要运行`menuconfig`命令，在
|
||
`Hardware Drivers Config -> On-chip Peripheral Drivers`中使能对应的外设接口，
|
||
但是由于针对不同的外设接口GPIO的pinux配置不一样，开发者仍需要根据自己的需求
|
||
在 `board/board.c` 中的 `rt_hw_drivers_init`入口函数中找到需要使用到的子函数，
|
||
并在对应的子函数中进行功能适配。
|
||
|
||
**使用举例**
|
||
|
||
* I2C外设Pinmux
|
||
|
||
如果需要将I2C1的SCL和SDA配置在PB10和PB11，首先需要在menuconfig中将I2C1使能，然后
|
||
更改board.c中`rt_hw_i2c_drvinit`函数，并进行如下设定。
|
||
|
||
~~~c
|
||
/* Configure PB10 PB11 (I2C1 SCL SDA) as alternate function */
|
||
gpio_init(GPIOB, GPIO_MODE_AF_OD, GPIO_OSPEED_50MHZ, GPIO_PIN_10 | GPIO_PIN_11);
|
||
~~~
|
||
|
||
* SPI外设Pinmux
|
||
|
||
如果需要将SPI0的SCK MISO和MOSI配置在PA5, PA6和PA7，首先需要在menuconfig中将SPI0使能，
|
||
然后更改board.c中的`rt_hw_spi_drvinit`函数，并进行如下设定。
|
||
|
||
~~~c
|
||
/* Configure PA5 PA6 PA7 (SPI0 SCK MISO MOSI) as alternate function */
|
||
gpio_init(GPIOA, GPIO_MODE_AF_PP, GPIO_OSPEED_50MHZ, GPIO_PIN_5 | GPIO_PIN_7);
|
||
gpio_init(GPIOA, GPIO_MODE_IN_FLOATING, GPIO_OSPEED_50MHZ, GPIO_PIN_6);
|
||
~~~
|
||
|
||
* 其余类似的外设也是如上做适配处理
|
||
|
||
### 注意
|
||
|
||
- 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。
|
||
- GD32VF103的驱动适配开关在 `menuconfig -> Hardware Drivers Config -> On-chip Peripheral Drivers` 可以找到。
|
||
- HWTIMER和PWM都是采用的TIMER模块进行功能实现，所以在使用驱动时，请务必注意不要重叠使用相同模块。
