Hallo All, I'm using win8.1_64bit, matlab 2014a. I'm using STM32F4DISCOVERY board, and I have a problem to load and run the code. I have no problem to generate the code using matalb, then I can load it by ST-link utility without problem. when I set the configuration to build, load and run, I got this error:
"C:\MATLAB\SupportPackages\R2014a\stm32f4discovery/openOCD_client.bat" "C:\MATLAB\SupportPackages\R2014a\openocd-0.6.1/bin/openocd-0.6.1.exe" "-f board/stm32f4discovery.cfg" ../stm32f4discovery_led4.hex ### Launching openOCD server C:\MATLAB\SupportPackages\R2014a\openocd-0.6.1/bin/openocd-0.6.1.exe -f board/stm32f4discovery.cfg: Following error captured during invoking of openOCD server:

Could you please help me? Best regards,
