准备批处理

搜索exe批处理

find_file.bat

@echo off:: 自动识别脚本名和路径
set "SCRIPT_DIR=%~dp0"
set "SCRIPT_NAME=%~nx0":: 检查是否提供了正确的参数

读取bin数据解析

read_bin.py

import struct
import sysdef read_u32_from_bin(file_path, offset):with open(file_path, "rb") as f:f.seek(offset)data = f.read(4)if len(data) < 4:print("文件数据不足。")return Nonereturn struct.unpack("<I", data)[0]  # "<I"表示以小端序读取无符号32位整数if __name__ == "__main__":if len(sys.argv) != 2:print("用法: python read_bin.py <文件路径>")sys.exit(1)file_path = sys.argv[1]u32_value = read_u32_from_bin(file_path, 4) # 跳过前4个字节，读取接下来的4个字节if u32_value is not None:hex_value = hex(u32_value)print(f"{hex_value}")

调用jlink批处理

准备jlink脚本

flash_ram.jlink

// 连接设置
device Cortex-M3
si 1
speed 4000// 重置并停止目标设备
r
h// 下载二进制文件到RAM，路径和地址根据实际情况替换
loadbin BIN_FILE_PATH LOAD_ADDRESS// 设置中断向量表地址（假设中断向量表地址为0x10000000）
w4 0xE000ED08, 0x10000000// 读取中断向量表的第一个条目（初始堆栈指针值）
mem32 0x10000000, 1// 读取中断向量表的第二个条目（复位）
mem32 0x10000004, 1// 设置PC寄存器为读取的第二个32位值
setPC PC_VALUE// 执行程序
g// 等待程序执行
//wait 1000// 停止设备
//halt// 读取并输出当前的PC寄存器值
//regs// 退出J-Link
q

以下设置信息都可在map文件找到
设置SP

设置中断向量表

设置PC = Reset_Handler地址

调用执行
