C2000 Embedded coder -- Change default time-out

Hi all,

I am trying to run a model in external mode, but keep getting the error " Unable to connect to the 'TI Delfino F2833x' target for ..." and " 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 first connect response packet. Possible reasons for the time-out:"

When I type command ticcs into Command Window I get:

>> ticcs

TICCS Object:
  Processor type   : TMS320C28xx
  Processor name   : TMS320C2800_0
  Running?         : No
  Board number     : 0
  Processor number : 0
  Default timeout  : 10.00 secs

    RTDX channels    : 0

If I reduce the number of elements in the model, I can connect. I suspect time-out is too low.

How to change time-out?

Hi Mike,

Usually the External mode time out is more then enough and the fact that you hit it probably means that you have a connection problem. I'm not sure which version of MATLAB you are using and what connection you are trying to use. We support CAN and Serial for TI C2000.

• Here is a detailed description on how to run External mode for serial: Parameter Tuning and Signal Logging with Serial External Mode
• If using serial, you might find this page useful as well: Set Up Serial Communication with Target Hardware.
• If using an XDS100 based board (LaunchPad, controlCards, docking stations, TI evaluation boards, etc.), here is a useful page to setup the serial port of the XDS100: Using the serial adapter of XDS100

I hope it helps,

Antonin.
