stm32 bootloader

STM32 bootloader是一种用于在STM32微控制器上进行固件升级的引导程序。当BOOT0引脚为高电平时，系统存储器中的引导加载程序将在复位后执行。这个引导加载程序通常在出厂时由官方固化在单片机中的一段代码，用户无法修改。在STM32中，常用的串口下载和DFU（Device Firmware Upgrade，设备固件升级）就是通过系统引导加载程序来实现的。

对于STM32F4系列来说，系统引导加载程序的地址是0x1FFF0000。为了正确跳转到引导加载程序，需要将其地址映射到0x00000000。

有关STM32的UART引导加载程序，可以参考官方提供的文档《Programming an external Flash memory using the UART bootloader built-in STM32 microcontrollers, software expansion for STM32Cube (AN4852)》。这个引导加载程序还支持通过Quad-SPI外部存储器进行固件编程。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
