Error: Core panicked IllegalInstruction

[Marceeel]

Hello, I have a problem in monitor serial. It sends me back the error IllegalInstruction. I have been looking for several days but I didn't find the solution..

Please help me

Seems your log states it sends back LoadProhibited, not IllegalInstruction, and that it happens somewhere in the log() function of your sketch. Without you posting your code, that's about all we can say about that.
