When using JT-LINK to simulate and debug the program, after just a few minutes of debugging, a prompt appears that CORTEX-M cannot be found. What is the reason? The code has been debugged for a long time. How could this error occur? Is it possible that the previously debugged code is not running in the MCU?

Pirated.

Thank you very much. Do you mean my emulator is pirated, or is KEIL5 pirated?

Check the JT-LINK cable.

My JLINK is not pirated. It can only debug one file LED.C. If I change the name to another one, it won't work.

There are many possible reasons for this, such as insufficient power supply, unstable reset pin, hardware welding problems, etc.
