STM32 USB-DFU说明
一：CUBEMAX配置
1.USB驱动选择
2.引脚一览
3.USB配置
#define FLASH_DESC_STR "@InternalFlash /0x08000000/03*016Ka,01*016Kg,01*064Kg,07*128Kg,04*016Kg,01*064Kg,07*128Kg"上面的这个是默认生成的,stm32f407的扇区配置，我们的事STM32F103RCT6 扇区大小2K 共128个,修改如下
#define FLASH_DESC_STR "@Internal Flash /0x08000000/24*002Ka,104*002Kg"boot区24*2=48k 该参数配合图三设置的 0x0800c000,该新芯片后面的扇区大小一样所以直接104*2即可，407的因为扇区大小不一样所以分开写，其他芯片看手册即可
0x0800c000为APP程序的起始空间地址
二： boot代码介绍
1.usbd_dfu_if.c修改 不同IC区别只有扇区擦除函数有差异,最后那个状态获取函数随便填个时间就行
