rt-thread上的STM32虽然没有F2系列的BSP，但芯片同样也是coretx-M3架构，正好手头上有微雪电子的stm32f205rb板子，就基于F1系列的BSP开始修改。

前期准备
STMCUFinder
cubemx
Rt-thread v3.13

cubemx里面f2固件更新到最新
下载安装好Keil.STM32F2xx_DFP.2.9.0.pack

step1:
从stm32\libraries\templates里面复制stm32f10x并改名为stm32f20x，清空board\CubeMX_Config里面的文件![step1.jpg](/uploads/201910/19/175656w6p13l7nvf1wuffg.jpg)step2:STMCUFinder里面选中stm32f205rb双击自动执行cubemx。选用uart1, usb device,开中断，配置好clock，起好项目名并生成代码，再把生成的代码项目文件剪切到上一层，重新打开cubemx的项目，这样以后重新生成的代码文件目录不会改变。

step4:
在stm32\libraries下新建目录STM32F2xx_HAL，将上面cubemx生成的代码drivers下的驱动库复制到STM32F2xx_HAL里面，SConscript脚本就复制F1的好了，修改SConscript的内容，注意的是F2没有xx_cec.c和xx_gpio_ex.c。修改stm32\libraries下的Kconfig，添加SOC_SERIES_STM32F2。回到stm32\stm32f20x目录，修改目录下的SConstruct脚本中的stm32_library在此目录下开启env，menuconfig配置好保存， scons 重新生成项目，打开project会发现已经添加好F2库，options选stm32f205rb。编译发现drv_dma.h报错，UART1_CONFIG undefined报错drv_dma.h添加SOC_SERIES_STM32F2，在stm32\libraries\HAL_Drivers\config下新建f2目录，将f1的文件复制到f2；回到stm32\libraries\HAL_Drivers下修改drv_config.h；再编译drv_uart报错,修改drv_usart.h添加SOC_SERIES_STM32F2。编译无误，下载固件顺利运行。

menuconfig选好 USB device --> win usb，scons重新生成项目，可以看到已经有了rt_usbd库，编译无误，下载运行。插上USB显示rtt win usb，注意cubemx里面NVIC要开启USB 中断。
