Error related to OpenOCD with Matlab206b

Hello everyone, I'm using a STM32F4-Discovery and Matlab2016b. I've downloaded the Embedded coder support package for STM32F4. When I try to do an External Mode Simulation with a simple ADC Block and a Display Block, I've the following error :

• The following error occurred during deployment to your hardware board: Error while writing the executable to the STM32F4 flash. OpenOCD returned the following diagnostic message:### Launching openOCD server "C:\Program Files\GNU ARM Eclipse\OpenOCD\0.9.0-201505190955\bin\openocd.exe" -f board/stm32f4discovery.cfg: readline() on closed filehandle $fh at C:\ProgramData\MATLAB\SupportPackages\R2016b\toolbox\target\supportpackages\stm32f4discovery\openOCD_client.bat line 69.Success### Open telnet port for communction with openOCD server.Unable to open a telnet connection to OpenOCD. If you are already connected to OpenOCD via a telnet or a GDB connection, please close the connection. For more information look in the logfile generated by openOCD: C:/Documents/MATLAB/matlab 2016b/STM32-Embeeded Package/test1/test1_ert_rtw/mw_openocd_log.txt. at C:\ProgramData\MATLAB\SupportPackages\R2016b\toolbox\target\supportpackages\stm32f4discovery\openOCD_client.bat line 162.*

I've seen many answers about this same issue but for less recent version of Matlab. Actually I don't have any C:Program\MATLAB\SupportPackages\2016b\openocd file in which I could rename the openocd executable file, so the solution given previously can't work here.

Hi Steve, try with the following steps:

1. Open the folder "C:\Program Files\GNU ARM Eclipse\OpenOCD\0.9.0-201505190955\scripts\board"

2. Edit the file "stm32f4discovery.cfg" in a text editor.

3. Change the next line

source [find interface/stlink-v2.cfg]

to

source [find interface/stlink-v2-1.cfg]

4. Restart Matlab, open the simulink model and Deploy to Hardware.
