Save statefile inside a Hook (it hangs) via python script about renode

[asmitaj08]

Hi,
I referred Load and Save feature - https://renode.readthedocs.io/en/latest/basic/saving.html
I was wondering if there is any other way to do it via Python, instead of m.execute(f"Save @{state_file}") ?
Thanks!

I tried EmulationManager.Instance.Save(state_file), but same issue. It just hangs when I do it inside the hook. Unable to figure out. Or is there any other way in which I can save the resister context (snapshot) at a particular address ?
Also, I tried doing it differently, i.e. saving the sate outside based on the flag which is enabled inside the hook. Like :

while reach_target_flag == 0:
    pass
if reach_target_flag == 1:
    mach.sysbus.cpu.Pause()
    try:
        EmulationManager.Instance.Save(state_file)
        print(f"Save command executed: Save @{state_file}")
    except Exception as e:
         print(f"Error executing save command: {e}")
    print("reached flag")
    reach_target_flag = 0

Where reach_target_flag is set inside hook. But it gives me error :
Error executing save command: Error encountered during saving: Pointer or ThreadLocal or SpinLock encountered during serialization.

Some help/suggestions would be appreciated. Thank you!

Able to solve after I removed the Hook, after the flag is set in the 2nd approach.
