简短教程

本来是写了不少的, 但是因为这个编辑器的问题, 因为提前填好了验证码,验证码栏尾部也呈现 绿色√, 然后再写的帖子,

结果发表帖子的时候提示 验证码 错了, 然后就强制返回到编辑页面, 也只有标题还在了, 内容全部消失了.................

搭建环境
让小安派 Ai-M61-32SU 进入烧录模式
1. 长按不放开 Type-C 右侧的烧录按钮 -[IO2] (中文名:烧录|英文名:Flashing)
2. 按一下 Type-C 左侧的重置按钮 -[EN] (中文名:重置|英文名:Reset)
3. 松开先前长按的烧录按钮, 则进入烧录模式了
  1. 图片来源:[[持续更新]小安派S1&M61从编译到烧录]
修改 //AiPi-Open-Kits/aithinker_Ai-M6X_SDK/examples/peripherals/gpio/gpio_input_output 里的 main.c, 将 main.c 的内容替换为下面贴出的 核心代码
开始烧录程序到 小安派上
1. terminal 进入 //AiPi-Open-Kits/aithinker_Ai-M6X_SDK/examples/peripherals/gpio/gpio_input_output 目录
2. terminal 输入以下内容
3. make clean
4. make
5. make flash CHIP=bl616 COMX=/dev/ttyUSB0
  1. 其中 COMX=/dev/ttyUSB0 则需要替换 [/dev/ttyUSB0] 为你电脑上小安派实际接口
  2. Linux 环境下输入 ls /dev/tty* 可用查看所有端口, 例如: [COMX=/dev/ttyUSB0]
  3. Windows 环境下用设备管理器查看小安派实际 COM, 例如: [COMX=COM5]
6. 烧录结束之后, 点击小安派的 Reset 按钮一下, 烧录的程序则开始运作.
