右下图情况是由于没有正确装载Driver导致,可以通过右击“DFU in FS Mode”选择更新驱动程序软件\浏览计算机以查找驱动程序软件(驱动文件位于DfuSe v3.0.5安装目录\DfuSe v3.0.5\Bin\ Driver)。 打开DfuSeDemo,结合下图步骤,点击’Choose’加载之前转换的.dfu文件;选择配置;点击’Update’完成擦除与下载;另外,可以...
利用USB DFU实现IAP功能
1.下载STM32_USB-FS-Device_Lib_V3.2.1.rar 2.安装DfuSe_Demo_V3.0_Setup.exe。 3.打开...\STM32_USB-FS-Device_Lib_V3.2.1\Project\Device_Firmware_Upgrade\MDK-ARM\DFU.uvproj 修改://#define ApplicationAddress 0x08003000为#define ApplicationAddress 0x08004000(因为要修改程序增加空间) 编译程序,...

为了能使STM32F103C8进入DFU模式,选择一个按键作为进入DFU模式的开关,此处我选择PA5(COL5)和PA15(ROW3)这连个IO进行设置,然后通过程序使得当按下某个键,再插上USB后进入DFU模式。 然后我们生成代码,修改usbd_dfu_if.c文件: //Flash初始化,即解锁FLashuint16_tMEM_If_Init_FS(void){/* USER CODE BEGIN ...
