GNU屏幕

在终端中运行

  sudo屏幕port_name 115200 
  

请参见下文（ 步骤2 ）找出 port_name ，例如 / dev / ttyUSB0 。按 Ctrl-A ，然后按 K ，然后按 Y 退出屏幕。如果未安装，请执行 sudo apt-get install屏幕。

Minicom

• 简短回答

在终端中运行

  sudo minicom -b 115200 -o -D port_name 
  

请参见下文（第2步）以找出 port_name ，例如 / dev / ttyUSB0 。按 Ctrl-A ，然后按 X 退出 minicom 。

• 长答案（UI）

minicom 应该正确配置才能打开连接。常规步骤如下：

1. 安装 minicom with

     sudo apt-get install minicom 
     




2. 
   
   

   其中 ttyUSB0 是委员会。

   
   

   3. 运行 minicom 并选择串行端口设置，并带有

        sudo minicom -s 
        

   
   

   您应该看到

   
   
   
   
   
   4. 检查（或设置） tty 连接的设置。确保 / dev / ttyX 与您的连接相对应，该连接是您在步骤2中获得的，而不是 X ，和 Bps / Par / Bits 按照
      
      
      5. 现在点击退出并且，如果一切都已正确设置，则连接应该正在运行。如果键入 ls 命令，您应该会看到 Android Thing 的根目录
      
      
      
      
      6. 对于退出 minicom ，按 Ctrl-A ，然后按 Q ，然后是：
      
      
      
      

      I've been trying to connect to the serial console of a Raspberry Pi 3 with Android Things using USB to TTL cable from my Linux (Ubuntu) machine. Despite I connected the cable as per the documentation, all I get when executing the minicom command is the following

      with no chance to type in any character. So I neither can see any kernel messages nor shell into the device.

      What am I missing?

      GNU Screen

      Run in terminal

      sudo screen port_name 115200
      

      See below (step 2) to find out port_name, e.g /dev/ttyUSB0. Hit Ctrl-A, then K, then Y to exit screen. Execute sudo apt-get install screen if not installed.

      Minicom

      • Short answer

      Run in terminal

      sudo minicom -b 115200 -o -D port_name
      

      See below (step 2) to find out port_name, e.g /dev/ttyUSB0. Hit Ctrl-A, then X to exit minicom.

      • Long answer (UI)

      minicom should be properly configured in order to open the connection. The general steps are as follows:

      1. Install minicom with

         sudo apt-get install minicom
         

      2. Connect Rpi3 with your host machine using USB-to-TTL cable and open the terminal. Find the tty connections with

         dmesg | grep -e tty
         

      In my case I get

      where ttyUSB0 is the board.

      3. Run minicom and select the serial port setup with

         sudo minicom -s
         

      You should see

      4. Check (or set) the settings for the tty connection. Make sure that /dev/ttyX corresponds to your connection, the one you get in the step 2 instead of X, and Bps/Par/Bits set as per the documentation.

      Similar to

      5. Now hit Exit and, if everything had been properly set up, the connection should be running. If you type the ls command you should see Android Thing's root directory
      6. For exiting minicom hit Ctrl-A, then hit Q, then Yes:
