首先用STM32CubeMX 软件搭建基础工程,来作为二级BootLoader,一级BootLoader是STM32官方自带的startup_stm32f407zgtx.s。我们基于上述最小工程来实现Customer BootLoader的功能。本项目采用的是通过串口实现固件…
Microcontroller address space We will create two projects – one for the bootloader itself and one for the application code. The bootloader code will: execute after power-on-reset check if a button is pressed if so, it will initialize the UART erase the application code flash space wait for ...
@stm32使用i2c或uart实现自举,bootloader自举程序激活说明通过配置特定“系统存储器”配置中的 BOOT0 和 BOOT1 引脚(请参见表 2),然后执行复位即可自动激活自举程序。根据所用引脚配置的不同,可选择 Flash、系统存储器或 SRAM 作为自举空间1.下载编译stm32flash工具$ g
