Debugging a frozen module

[davefes]

I found this clue:

py: Only search frozen modules when '.frozen' is found in sys.path.

What if you want to work on one out of several frozen modules and you don’t have enough flash to “unfreeze” all of them?

The problem I am having is trying to debug micropython/lora on a STM32WL5x board with very limited space on it’s LFS2 filesystem.

Is there some way to have a file on /flash override one that is baked-in?

If you change sys.path to have flash before frozen you can replace one module, eg
sys.path.insert(0, '/flash')

Great I will give a try.
