本次测试STM32F407ZGT6的离线功能。

一、准备固件

因为测试的是STM32F407ZGT6的烧写，刚好手头有款原子的探索者，顺手就用上了。反正都是JTAG，都连的上。

LVGL的功能，固件比较大，hex size为716K。

二、固件上传至烧写器

离线烧写固件，第一步是将生成的固件上传到fireFlasher Mini 脱机烧录器，打开野火脱机烧录器上位机，直接识别出MCU，然后选择“加载固件”将需要上传的固件导入，比较大的话，上位机会提示是否切分。

[21:00:31.758]>>>已连接到fireFlasher_Mini
[21:00:43.124]>>>当前MCU型号: STM32F407ZG

选择“一键烧录”，将固件上传至fireFlasher Mini 脱机烧录器。

选择“退出配置”，退出FlashLoader状态，此时固件已经上传至 fireFlasher Mini 脱机烧录器，马上就可以单独使用脱机烧录器给开发板烧录程序了。

[21:01:19.972]>>>已退出配置，长按连接到上位机，或者重新插拨烧录器usb

[21:01:20.089]>>>fireFlasher_Mini 已断开连接

三、一键烧写

此时可以拔掉type-c连接线，保留fireFlasher Mini 脱机烧录器与开发板的JTAG连接即可，按下红点键，此时绿灯闪烁，随着滴的一声，固件离线烧写完毕。
