Nano 33 BLE Sense Crash on Machine Learning

Development Tools IDE 1.x

Hi, I recently got Nano 33 BLE Sense and want to perform a machine learning project. I first try the existing gesture recognization project found here: https://github.com/arduino/ArduinoTensorFlowLiteTutorials/blob/master/GestureToEmoji/ArduinoSketches/IMU_Classifier/IMU_Classifier.ino
After I upload the program there is no error. But when I open the serial monitor/plotter, the yellow light is flashing slowly (which I assume the program is crashing) and I can't close the serial monitor. After I press the reset bottom, yellow light stop flashing. I debug step by step and find that when I add machine learning code in the setup part, it will cause this problem. Specifically, the code that causes this problem is (tflInterpreter = new tflite::MicroInterpreter(tflModel, tflOpsResolver, tensorArena, tensorArenaSize, &tflErrorReporter);
The code should be correct since I see several people have successfully implemented this code. But I don't why it failed on my board. Thanks.

Try making this change to see if it fixes it:

Oh, it works after I follow the file and change that byte boundary for tensorArena. Thanks a lot.

You're welcome. I'm glad to hear it's working now. Enjoy!
