Hello everyone, I am experiencing difficulties when trying to open "Monitor & Tune" in Matlab to read a digital signal from the User button. I am using the NUCLEO-144H723ZG board. While I can successfully "Build and start" the LED control project, clicking "Monitor & Tune" does not work.

I am certain that I have already checked the COM port accurately.

You can refer to the following link for external mode debugging steps: https://www.mathworks.com/matlabcentral/answers/2048172-why-am-i-receiving-a-xcp-internal-timeout-error-when-starting-external-mode-on-an-stm32-board-using

An issue with the COM port could also lead to the displayed error. Try changing the COM port in device manager (https://www.startech.com/en-eu/faq/change-com-port-number-windows), and in the Simulink hardware settings.

If the problem still persists, contact MathWorks Technical Support: https://in.mathworks.com/support/contact_us.html
