启动开发板
开发板启动连接接口如下：
接入③12v电源接口、①OTG和②串口。拨动电源开关（拨动开关朝上图的右边拨动，OTG线不供电），即可启动开发板。
windows下使用 ADB登录系统
连接OTG线
将开发板配套的两根typec线，一根 直接连接至 开发板 OTG烧录接口 另一头连接至电脑的USB接口，开发板默认有系统，接通otg电源线就会通电并直接启动。
安装windows板ADB
点击链接下载Windows版ADB工具 ADB.7z 下载完成后解压，可以看到如下目录，
然后 我们单独 拷贝 上一层的 platform-tools 文件夹到任意 目录，拷贝完成后，记住这个 目录位置，我们接下来要把这个 路径添加至 Windows系统环境变量里。
我这里是把它单独拷贝到了 D盘，我的目录是 D:\platform-tools 接下来 我需要把它单独添加到Windows系统环境变量里面才可以在任意位置使用adb命令。
添加到 Windows系统环境变量里面
打开cmd连接开发板
打开CMD Windows 命令提示符方式有两种
方式1：直接在Windows10/11搜索对话框中输入 cmd 在弹出的软件中点击 命令提示符
方式2：同时按下 wind + r 键，输入 cmd 命令，按下确认 就可以自动打开 命令提示符
打开命令提示符，输出 adb命令可以直接看到我们的adb已经配置成功
连接好开发板的 OTG 并将其连接至电脑上，然后 输入 adb shell就可以自动登录系统

ADB 也可以作为文件传输使用，例如：
C:\System> adb push badapple.mp4 /mnt/UDISK # 将 badapple.mp4 上传到开发板 /mnt/UDISK 目录内
C:\System> adb pull /mnt/UDISK/badapple.mp4 # 将 /mnt/UDISK/badapple.mp4 下拉到当前目录内
使用串口登录系统
1. 连接串口线
将配套的TypeC线一段连接至开发板的串口/供电接口，另一端连接至电脑USB接口，连接成功后板载的红色电源灯会亮起。 默认情况下系统会自动安装串口设备驱动，如果没有自动安装，可以使用驱动精灵来自动安装。
- 对于Windows系统
此时Windows设备管理器 在 端口(COM和LPT) 处会多出一个串口设备，一般是以
USB-Enhanced-SERIAL CH9102开头，您需要留意一下后面的具体COM编号，用于后续连接使用。
如上图，COM号是96，我们接下来连接所使用的串口号就是96。
- 对于Linux系统 可以查看是否多出一个/dev/tty 设备,一般情况设备节点为 /dev/ttyACM0 。
2. 打开串口控制台
获取串口工具
使用Putty或者MobaXterm等串口工具来开发板设备。
- 其中putty工具可以访问页面 https://www.chiark.greenend.org.uk/~sgtatham/putty/ 来获取 。
- MobaXterm可以通过访问页面 https://mobaxterm.mobatek.net/ 获取 (推荐使用)。
使用putty登录串口
使用Mobaxterm登录串口
打开MobaXterm，点击左上角的“Session”，在弹出的界面选中“Serial”，如下图所示选择端口号（前面设备管理器显示的端口号COM21）、波特率（Speed 115200）、流控（Flow Control: none）,最后点击“OK”即可。步骤如下图所示。 注意：流控（Flow Control）一定要选择none，否则你将无法在MobaXterm中向串口输入数据
3. 进入系统shell
使用串口工具成功打开串口后，可以直接按下 Enter 键 进入shell，当然您也可以按下板子上的 Reset复位键，来查看完整的系统信息。
