[question] kernelpatch develop

[Empier]

I'm trying to develop a feature that retrieves the return address when performing a hook, so I can identify where the function was called from.
However, when I try to build KPImg and perform intermediate testing, it seems like I have to patch the boot.img and flash the device every time.

Is there a simpler or more efficient way to apply changes without having to reflash the boot image each time?
