移远通讯BC260Y CN STM32G0串口下载教程
下载前，需要先断电并将BOOT0处红⾊开关拨 ⾄“NO”，并再次接上数据线，打开STM32CubeProgrammer，选择UART模式，点击右上⻆的“Connect”按钮，显示绿⾊“Connected”图标时即为连接成功
点击左侧的下载图标，进⼊Erasing & Programming界⾯，并点击“Browse”选择需要的烧录的 程序
点击右上⻆的“Disconnect”按钮断开连接，并断电，将底板上的红⾊开关码拨到“1”，拔掉数据线重启后再连接。
下载好后显示的灯
一个红色1个蓝色常量
注意下载的时候波特率是115200，使用串口软件是9600 ，程序路径不要有中文
