Sometimes a long async blocking hint is useful for debugging. Maybe make it depend to #if (DEBUG_LEVEL >= 7) instead of MAIN_DEBUG?

I agree that long async blocking hint is useful to have. Dependency on DEBUG_LEVEL 7 would be fine.

okay, I would like to suggest that this check is disabled by default.
it should only be enabled if explicitly compiled in, e.g. MAIN_DEBUG or DEBUG_LEVEL.

also, a threshold of 100ms seems a bit low. perhaps 500ms is better.

on embedded platforms, this warning comes up quite a lot due to slow CPU.

Yes, 500ms would be better.

please have a look at the last commit.

MAIN_DEBUG and TMR_DEBUG is off by default.

it can be enabled explicitly:

make EXTRA_CFLAGS=-DMAIN_DEBUG=1
