TI C2000 Delfino 28335 - Error Unable to connect to the 'TI Delfino F2833x' target for 'c28x_serial_ext'.

조회 수: 15 (최근 30일)
I can't run successfully c28x_serial_ext on a Delfino F28335 Dockcard. Hardware itself is working fine, since I can run my own programs from CCS 7.1.0 and CCS 6.2.0.
I have one TMP100 I2C temperature sensors connected to dock pins 32 and 33 and no other hardware attached.
I've set baud rate to 115000 in Control Panel -> Device Manager, matching example instructions and Configuration Parameters. Also tried a slower baud (9600), setting it both in Device Manager and Configuration Parameters. I notice there is an initial communication, since LEDs are reset after I click Run, then one LED goes up and gets locked.
Here is the error message:
Error occurred while executing External Mode MEX-file 'ext_serial_win32_comm': Failed to connect to the target. A time-out occurred while waiting for the connection response from the target. Possible reasons for the time-out: a) The target is not switched on. b) The target is not connected to your host machine. c) The application for the model is not running on the target. You might have clicked the Stop button. If the Run button is not dimmed, click it. Otherwise, click the Build button, which downloads and runs your application on the target. Component: Simulink | Category: Model error Unable to connect to the 'TI Delfino F2833x' target for 'c28x_serial_ext'.

Hi I have the same problem with c28x_serial_ext. Did you find any solution?
I really need real-time logging and tuning.

Could you please check on the following points:
1. Ensure the GPIO pins for SCI_A port and the one configured on simulink are same. 2. Ensure the COM port as detected in device manager is same as specified in the external mode pane. http://processors.wiki.ti.com/index.php/Using_the_serial_adapter_of_XDS100 3. Also ensure the jumper settings on the DOCK and any DIP switch on control card are in a position to support serial communication. https://www.mathworks.com/help/supportpkg/texasinstrumentsc2000/ug/set-up-the-hardware-target.html
