Cycle counter works only when a program is loaded by debugger.

[suikan4github]

Describe the bug The Cycle counter runs only when a program is loaded by the debugger. This seems to be like :

• Cold Reset: The cycle counter runs.
• Warm Reset: The cycle counter doesn't run.

Pushing the reset button on Nucleo Board makes a warm reset. In this case, the cycle counter shows the same random value.

To Reproduce Steps to reproduce the behavior:

1. Load the program by a debugger to a debuggee.
2. Run it. We will see the cycle counter runs on the terminal.
3. Push the reset button.
4. We will see the cycle counter runs on the terminal.

Expected behavior The cycle counter runs always.

Screenshots The following is when the program is loaded by the debugger and run.

The following is when the program is just reset by the debugger.
