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.

I encountered a similar issue when trying to use "Monitor & Tune" with my NUCLEO-144H723ZG board in MATLAB R2023b.
I found that using an old ‘.ioc’ file caused problems. When I created a new ‘.ioc’ file directly from Simulink, it worked and allowed the board to enter the External Mode.
By generating a new ‘.ioc’ file, I was able to get "Monitor & Tune" to function properly. I suggest giving this a try to see if it resolves your issue.
