HAL库U盘升级 STM32F407 CUBEMX：FATFS + USB_HOST + USB_OTG_FS

时间：2022-03-07 13:03:06

一、测试平台：

MCU:STM32F407VET6

固件库：CUBEMX

IDE:MDK

二、实验目的：

将U盘里面的bin文件插入要升级的设备，通过BootLoader来进行升级

在这是用板载的LED灯来显示升级情况：

不进行升级：LED灯是灭的状态

升级成功：LED灯以100ms在闪烁

接下来先进行BootLoader的配置以及程序编写，再配置APP

三、BootLoader：

1 下载器配置

2 时钟源配置

3 LED配置

4 串口配置开启全局中断

5 USB_OTG_FS配置

6 USB_HOST配置

7 FATFS配置

8 时钟树配置 48M是用来操作U盘的，所以必须要有

9 工程配置

10 生成工程

11 创建两个空白文件文件
