Unable to download program to STM32F4 Discovery Board using OpenOCD and simulink

Hello All,

I am trying to run example "Getting Started with STMicroelectronics STM32F4-Discovery Support Package"

in MATLAB Simulink. I could build the program and generate .hex and .bin file. But I am unable to download and run that on the hardware. While deploying program to hardware, I got following error -

-------------------------------------------------------------------------------------------

Can you suggest a solution?

Thanks & Regards,

I have this problem too. Unfortunately, I could not find solution.

me too, my solution, change .hex file with st-link utility
