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
