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刷新。 下面简单介绍一下二级BootLoder的功能与作用: 二级Customer
void bootloader_uart_read_data(void) { uint8_t rcv_len=0; printmsg_Host("BL_DEBUG_MSG: Receive CMD\n\r"); // 向主机打印调试信息,表示已准备好接收命令 while (1) { // 关闭指示灯,表示正在等待命令 HAL_GPIO_WritePin(LED2_GPIO_Port, LED2_Pin, GPIO_PIN_RESET); // 清空接收缓冲...
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
UART bootloader for STM32 microcontroller. Table of contents Introduction A bootloader for STM32F100 (STM32VLDISCOVERY board)[1]with UART and Xmodem protocol[2][3]. The software is created with Atollic trueSTUDIO and the drivers are generated with CubeMX. ...
STM32bootloader原理解释一、STM32的常规启动流程STM32的内部flash地址起始于0x8000000,一般情况下,程序文件就从此地址开始写入。此外STM32 butterflydw 2021-08-13 06:31:59 基于STM32开发板的UART收发空闲中断设计 有人在使用STM32的UART收发并开启空闲中断时,有时会发现空闲中断相比预期多进一次的情况。
