本次测试STM32F103RET6的离线功能。

一、业务场景

对于一些设备在户外，无法进行OTA升级，这个时候脱机烧录器就很贴心很好用了。

二、固件上传脱机烧录器

连接脱机烧录器到PC，选择MCU为STM32F103RET6, 把编译生成的hex文件，加载到APP，固件较大的时候，上位机APP会自动提示分段，点击确认即可。

点击上位机APP上的“一键烧录”，上位机软件会分析hex文件并将文件烧录至脱机烧录器。

三、脱机烧录

fireFlasher Mini 脱机烧录器使用SWD协议对芯片进行下载，不支持JTAG协议的接口。

既然只能SWD，那就4根线了，TMS + TCK， VREF + GND随便接接，脱机烧录器随带的线很赞，每根线头都有标记。

点击脱机烧录器的红色按钮，一会儿固件就从脱机烧录器烧写至目标开发板。
