参考代码 C#串口下载烧写bin文件 www.youwenfan.com/contentcsv/111953.html
三、使用说明
1. 硬件连接
-
将开发板的串口连接到电脑
-
确保开发板进入Bootloader模式
- STM32: BOOT0拉高，复位
- ESP32: GPIO0拉低，复位
-
连接电源
2. 软件操作
- 运行SerialFlashTool.exe
- 选择串口和波特率
- 选择协议类型
- 点击"浏览"选择Bin文件
- 设置烧写参数
- 点击"开始烧写"
3. 支持的芯片
- STM32系列: F0/F1/F2/F3/F4/F7/H7
- ESP32系列: ESP32/ESP32-C3/ESP32-S3
- GD32系列: GD32F103/GD32F303
- CH32系列: CH32F103/CH32V103
4. 常见问题
| 问题 | 解决方法 |
|---|---|
| 无法打开串口 | 检查串口是否被占用，以管理员身份运行 |
| 检测不到芯片 | 检查Boot模式，确认硬件连接 |
| 烧写失败 | 降低波特率，检查电源电压 |
| 校验失败 | 检查Flash大小，重新编译固件 |
5. 扩展功能建议
- 多文件烧写: 支持同时烧写多个Bin文件
- 加密烧写: 支持加密固件
- 批量烧写: 支持多设备同时烧写
- 自动检测: 自动识别芯片型号
- 日志记录: 保存烧写日志到文件
- 命令行支持: 支持命令行操作
