General • Timer Interrupt does not work with MacBook M2 + OpenOCD + GDB.

# My environment
Macbook Air M2 (Sequoia)
Raspberry Pi Pico (RP2040)
I am building a remote debugging environment using OPenOCD + GDB.
I have set up a debug probe on Pico.
I have wired the official docs and it works fine.

# My problem
I start OpenOCD and GDB and the program starts with the following command.
The timer interrupt process I set up is evaluated without any problems.
GDB> reset monitor

However, the timer interrupt process is not evaluated with the following command
GDB> monitor reset init
GDB> continue

# What I want to solve
Monitor reset does not allow me to set breakpoints or check variables.
The only way to debug is to put the process of flashing the LED in the code.

I would like to put a break or step execution on the interrupt process.

Has anyone encountered the same problem as me and solved it?
Please let me know how to solve it.

# Postscript.
I have found the register settings to be.
By setting a value in the timer register DEBUGPAUSE, the timer worked even when using DebugProbe.
DEBUGPAUSE.DBG0 <-- 0x00
DEBUGPAUSE.DBG1 <-- 0x00

Code added to the timer configuration.
Is this correspondence correct?
