Communications error: the communication channel could not be opened RM57Lx Launchpad

I'm working on this example "Processor-in-the-Loop Verification of Simulink Models" but i got communication error

Failed to open serial port '\\.\COM1'. The reported error code is: 2 or 0x00000002. Possible causes are: a) The target is not powered on. b) The specified port number is not correct. c) The specified bit rate is not supported by the host machine. d) The previous connection was not closed correctly. If this is the case, you may need to re-start MATLAB.

Communications error: the communication channel could not be opened.

I have checked this link http://processors.wiki.ti.com/index.php/Using_the_serial_adapter_of_XDS100 but i didn't got the answer as i already change the serial port in model paramaeter configuration as shown in attached picture.

What should i do to eliminate this error? need help in this regards

Hi muhammad usama,

When you encounter a communication error during Processor-in-the-Loop (PIL) verification of Simulink models, especially related to serial port issues, there are several steps you can take to troubleshoot the problem:

• Ensure that your target hardware is powered on and properly connected to the host machine via the serial port.
• Confirm that the serial port number you have configured in the Simulink model parameters matches the actual COM port number that the target hardware is connected to on your computer.
• Make sure that the “bit rate” you have specified in the Simulink model parameters is supported by both the host machine and the target hardware.
• Ensure no other applications are using the same COM port. Close any applications that might be using the COM port before attempting to connect again from MATLAB.

I hope this helps!

Best Regards,
