I run object_detection app from Hailo-Application-Code-Examples/runtime/cpp/object_detection/object_detection.cpp at main · hailo-ai/Hailo-Application-Code-Examples · GitHub
It works until 95% and then I get kernel error:
Unable to handle kernel NULL pointer dereference at virtual address 0000000000000000

I see, that error appears in function mutex_lock, but I can’t find, how object_detection.cpp connected with it. Where should I search for the problem function call?
