Using serial connection

The following illustration shows how to connect to the device using a null modem cable.

Any communication port on your PC can be used. Whereas, only Comm:2 port is used to connect on the device to avoid interference on Comm:0.

Setting up serial connection

The following procedure must be followed to set up the serial connection.

On the device

  1. Modify the stat.ini file as shown in the following example.

    [SectionOne]
    comport= 2 
    [SectionTwo]
    transport= serial
    [SectionThree]
    logging= 0
    debugport=1
  2. Set the com port to 2 for serial connection. This is because COMM:0 is usually unavailable and access is denied when trying to connect. (Logging should be left at 0, as it is only used for TestDriver debugging). The stat.ini file can then be included in the ROM in the sys\data directory or in the CF card in the sys\data directory.

On your PC

Connect a null modem cable to the com port of your PC and comm:2 of the device.

Example

The command-line option to run a test over a serial connection is:

> testdriver run -s root -p arm4 -b urel -s test1.test3 -t serialX

where, serialX specifies that serial communication port X on the PC.

NOTE: If -t option is not specified, the transport defaults to serial2 that is serial communication port 2.
