Installing minicom

The ARM and PowerPC bootloaders communicate with the host over a serial line at 9600 baud. The bootloader commands are issued over this serial link. The tbdev1 workstation requires a serial terminal emulation program called minicom to issue boot commands to the target boards. Here are the commands to install minicom on tbdev1:

root@tbdev1[531]: apt-get install minicom

After minicom is installed, you need to configure minicom's serial port by following these steps:

  1. Run minicom:

    root@tbdev1[532]: minicom
    
  2. Configure minicom by typing CTRL-a o, select "Serial port setup", and then change your settings to match these:

    A -    Serial Device      : /dev/ttyS0
    B - Lockfile Location     : /var/lock
    C -   Callin Program      :
    D -  Callout Program      :
    E -    Bps/Par/Bits       : 9600 8N1
    F - Hardware Flow Control : No
    G - Software Flow Control : No
    

    Exit from this screen.

  3. Select "Save setup as dfl", and then exit from this screen.

  4. Exit from minicom by typing CTRL-a q.

Now that the root filesystem is created and properly prepared, the TFTP server is configured, tested, and running, and minicom is installed, you are now ready to boot the target boards.
