I'm really new to this STM field. I recently bought a STM32f4 Discovery board after some testing it got a issue.

I'm using Keil 5 and matlab simulink for testing.

At the beginning it was working well and the program which comes with the board worked well(which work as a mouse).

Now I can upload the program without any error to the board and using STM utility can read the program too.

But the issue is program doesn't run. I tried few blinking programs and now worked.

If you have simple program that I can test please let me have it to test. If anybody experienced this before please let me know
