答案对人有帮助，有参考价值 0 鉴于flymcu下载时有点慢，flash_loader.exe容易卡死的原因，所以决定自己写个串口编程和控制台程序。然后写成bat文件，再整合到Visual studio的外部工具里，实现一键下载。 STM32_ISP的协议文档可以在st的官网上找到。先说下控制台的大致思路：程序的目标：把.bin文件通过指定串口发送到stm32,stm32把收到的.bin文件数据存到指定的flash地址。控制台这边要给的指令是：例如：COM4 256000 0X08000000 M:codedebugtext.bin 1.电脑的串口编号: COM4 2.要使用的串口波特率: 256000 3.编程地址: 0X08000000 4..bin文件路径: M:codedebugtext.bin 所有的指令可以通过int main(int argc, char* argv)，的argv指针获得。例如：把上面的指令通过CMD输入后程序： int main(int argc, char argv) { for (int i = 0; i < argc; i++) { printf("argv[%d]:%sn", i, argv); } } 运行结果： argv[0]:M:stm32_isp_programerstm32_isp_programmerDebugstm32_isp_programmer.exe argv[1]:COM6 argv[2]:256000 argv[3]:0X08000000 argv[4]:M:codedebugtext.bin 但是获得只是文本类型（char ）。 windows 要打开串口的话用需要用WCHAR 类型。所以要做一定的类型转换。字符串转WCHAR: #include wchar_t wstr[20]; swprintf(wstr, 20, L"%S", str); LPCWSTR wstr_p= wstr; 字符串转10进制字符串转16进制 #include long baudrate = strtol(setBuadrate_p, &endptr, 10); long writeAddress = strtol(writeAddress_p, &endptr, 16); 然后是打开串口： SerialPort.hSerial = CreateFile(filename, //lpFileName GENERIC_READ \| GENERIC_WRITE,//dwDesiredAccess 0, //dwShareMode NULL,//lpSecurityAttributes OPEN_EXISTING,//dwCreationDisposition FILE_ATTRIBUTE_NORMAL, NULL);//hTemplateFile 串口配制： SerialPort.NewDCBParams.BaudRate = baudrate; SerialPort.NewDCBParams.ByteSize = 8; SerialPort.NewDCBParams.StopBits = ONESTOPBIT; SerialPort.NewDCBParams.Parity = EVENPARITY; if (!SetCommState(SerialPort.hSerial, &SerialPort.NewDCBParams)) { printf("nSetCommState error!n"); fflush(stdout); return(1); } COMMTIMEOUTS timeouts = { 0 }; timeouts.ReadIntervalTimeout = 1000; timeouts.ReadTotalTimeoutConstant = 1000; timeouts.ReadTotalTimeoutMultiplier = 10; timeouts.WriteTotalTimeoutConstant = 50; timeouts.WriteTotalTimeoutMultiplier = 10; if (!SetCommTimeouts(SerialPort.hSerial, &timeouts)) { printf("nSetCommTimeouts error!n"); fflush(stdout); return(1); } 串口读写： DWORD serial_write(unsigned char* buffer, DWORD len) { DWORD lengthwrote; if (!WriteFile(SerialPort.hSerial, buffer, len, &lengthwrote, NULL)) { if (GetLastError() == ERROR_IO_PENDING) { printf("Error:%d Serial write fail, exiting lengthwrote:%dn", GetLastError(), lengthwrote); } printf("Error:%d Serial write fail, exiting lengthwrote:%dn", GetLastError(), lengthwrote); exit(1); } return(lengthwrote); } DWORD serial_read(unsigned char* buffer, size_t len) //windows version { DWORD bytesread; if (!ReadFile(SerialPort.hSerial, buffer, len, &bytesread, NULL)) { printf("Error: Serial read fail, exitingn"); exit(1); } return(bytesread); } 如果有加了RTS#控制的话，还可以用RTS来控制单片机复位： void hardwareReset() { UINT8 restTime = 5; while (restTime--) { if (!EscapeCommFunction(SerialPort.hSerial, SETRTS)) { printf("nEscapeCommFunction error in serial_config, SETRTSn"); fflush(stdout); exit(1); } Sleep(100); if (!EscapeCommFunction(SerialPort.hSerial, CLRRTS)) { printf("nEscapeCommFunction error in serial_config, SETRTSn"); fflush(stdout); exit(1); } Sleep(100); printf("%dn", restTime); } } 后面是STM32 ISP协议部分：主要用到这几个： void autoBaudrateStart(void);//自动识别波特率 void clear_writeprotect(void);//清除写保护 void get_version(void);//获取bootloader版本号，不同版本支持的指令不一样 void get_id(void);//获取芯片ID void globalerase_flash(void);//全片清除flash void program_memory(void);//flash编程然后是通信格式：基本是： 1字节命令+1字节命令反码 N字节内容+1字节所有内容字节的^（异或运算）通信流程：发送指令，等待ACK或者NACK,发送内容，等待ACK或者NACK 主程序： #include #include #include #include "Serial.h" #include "action.h" #include /* COM3 115200 0X08000000 D:SDALJGG.BIN / int main(int argc, char* argv) { SYSTEMTIME bootTime; SYSTEMTIME exitTime; char* selectPort_p; char* setBuadrate_p; char* writeAddress_p; char* loadFile; GetSystemTime(&bootTime); for (int i = 0; i < argc; i++) { printf("argv[%d]:%sn", i, argv); } selectPort_p = argv[1]; setBuadrate_p = argv[2]; writeAddress_p = argv[3]; loadFile = argv[4]; printf("selectPort:%sn", selectPort_p); printf("setBuadrate_p:%sn", setBuadrate_p); printf("writeAddress_p:%sn", writeAddress_p); printf("loadFile:%sn", loadFile); char endptr; long baudrate = strtol(setBuadrate_p, &endptr, 10); long writeAddress = strtol(writeAddress_p, &endptr, 16); hostHandle.baudrate = baudrate; hostHandle.loadFile = loadFile; hostHandle.serialDev = selectPort_p; hostHandle.writeAddress = writeAddress; serial_init(selectPort_p, baudrate); autoBaudrateStart(); get_version(); get_id(); clear_writeprotect(); globalerase_flash(); program_memory(); printf("Isp complete and reseting...n"); hardwareReset(); GetSystemTime(&exitTime); size_t timeUse = (exitTime.wMinute 60 + exitTime.wSecond) * 1000 + exitTime.wMilliseconds; timeUse = timeUse - ((bootTime.wMinute * 60 + bootTime.wSecond) * 1000 + bootTime.wMilliseconds);
