Regarding Reset

The Board I am using is NUCLEO-f767zi.The Board is getting reset after few minutes of usage. I am not sending any reset command at that time or not using hard_reset, but eventually board is getting reset. Please let me know if there is any way to solve this problem. Thanks in advance.

Thanks for reporting this.
Can you confirm which application you’re using and version of Mbed OS?

are you using windows and is the board connected to USB? Windows does something on the USB, I think it was the MSD. Can you try to disable it or to use some other supply (simple USB powerbank) and do not connect to the Windows host?
