Console from Workstation

Use a null modem cable to connect the ARM system to your workstation. If you do not have a COM port on your system (as many newer systems do not), you can find a USB serial adapter that will bring out RS232.

Console from Linux

There are many serial clients for Linux, but 3 simple ones would be picocom, screen, and minicom. These examples assume that your COM device is /dev/ttyUSB0 (common for USB adapters), but replace them with the COM device on your workstation.

Linux has a few applications capable of connecting to the board over serial. You can use any of these clients that may be installed or available in your workstation's package manager:

Picocom is a very small and simple client.

picocom -b 115200 /dev/ttyUSB0

Screen is a terminal multiplexer which happens to have serial support.

screen /dev/ttyUSB0 115200

Or a very commonly used client is minicom which is quite powerful:

minicom -s

• Navigate to 'serial port setup'
• Type "a" and change location of serial device to '/dev/ttyUSB0' then hit "enter"
• If needed, modify the settings to match this and hit "esc" when done:

     E - Bps/Par/Bits          : 115200 8N1
     F - Hardware Flow Control : No
     G - Software Flow Control : No

• Navigate to 'Save setup as dfl', hit "enter", and then "esc"

Console from Windows

Putty is a small simple client available for download here. Open up Device Manager to determine your console port. See the putty configuration image for more details.
