Part Number: TMS320F28035

I want to implement the matlab simulink model on Texas F28035 DSP. But when I run the program, below error occured. Can anyone help for this subject?

Error occurred while executing External Mode MEX-file 'ext_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:Block diagram errorUnable to connect to the 'TI Piccolo F2803x' target for 'untitled'.

Hi,

Also ensure the model step time is around 100usec or less i.e 1ms say. Many times, customer try to run the model with step times of say 1usec or 10usec which is doesn’t work with external mode.

If none of these helps, please contact Mathworks Technical Support @ www.mathworks.com/.../contact_us.html

Hi,

On the F28035 please check the position of the SW1 switch ON THE control card. The switch should NOT be towards the ON position. i.e if the switch is towards ON, pull it down.
On the USB docking station ensure the J9 connector is closed. This connector is Just besides the FTDI chip near the USB connector.

Dear customer,
We noticed that you rejected the resolution. As indicated by both TI & Mathworks, please pursue this issue with Mathworks, not on the e2e forum.

Please contact MathWorks Tech Support directly, as they do NOT read TI E2E forums. Please be prepared to send them your model for review, so they can assist you in getting it working.

Thanks,

-Brian

1] Be sure that you have correctly done what venkatesh chilapur said. If in doubt, you can read on your own the help documentation in Simulink about how to connect your control card [F28035].

2] Please read --> processors.wiki.ti.com/.../C2000_Archived_Workshops --> Piccolo Multi-Day Workshop Student Guide (pdf file) [last pages: Boot Selection Mode etc]
