STM32F4 simulink external mode error

Latest activity Answered by Abhishek GS on 18 Jun 2015
I am trying to run "stm32f4discovery_external_mode" example on stm32f4 discovery board. running on Matlab 64bit. getting the below error.
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: 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. Component: Simulink | Category: Model error
What could be the cause and fix for it? Thanks in advance.

This error message can be caused by a variety of factors. Can you try changing the duration of the model to "Inf", rebuild the model and then try to connect again ?
