RVSTAR开发板 是由芯来科技Nuclei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
硬件 | 描述 |
---|---|
内核 | Nuclei N205 |
架构 | 32-bit RV32IMAC |
主频 | 108 MHz |
请根据安装Nuclei RISC-V GCC Toolchain和OpenOCD 来安装依赖的工具。
将Nuclei RISC-V GCC Toolchain和OpenOCD的环境变量进行设置。
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
set PATH=D:\Software\Nuclei\gcc\bin;D:\Software\Nuclei\openocd\bin;%PATH%
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。
export PATH=~/Software/Nuclei/gcc/bin:~/Software/Nuclei/openocd/bin:$PATH
或者在ENV工具命令行中运行
export PATH=~/Software/Nuclei/gcc/bin:~/Software/Nuclei/openocd/bin:$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。
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。
运行 pkgs --update
来下载最新的依赖的Nuclei SDK开发包,修改链接脚本。
.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
可选: 运行 menuconfig
来进行内核配置
运行 scons -c
清理之前的编译结果
运行 scons
来进行代码的编译
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:

scons
命令。驱动 | 支持情况 | 备注 |
---|---|---|
UART | 支持 | RV-STAR板载串口是UART4, 默认使能 |
GPIO | 支持 | 默认使能,支持中断控制 |
SPI | 支持 | 默认关闭 |
I2C | 支持 | 默认关闭 |
HWTIMER | 支持 | 默认关闭 |
PWM | 支持 | 默认关闭 |
WDT | 支持 | 默认关闭 |
RTC | 支持 | 默认关闭 |
ADC | 支持 | 默认关闭 |
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
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。
/* 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);
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。
/* 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);
menuconfig -> Hardware Drivers Config -> On-chip Peripheral Drivers
可以找到。维护人:
