Program goes into hardfault mode on NUCLEO F767ZI, but not on NUCLEO H7S3L8

[s319189]

The code I’ve written in main.c for a program on NUCLEO H7S3L8 works perfectly fine, but on NUCLEO F767ZI goes into hardfault mode when reaching line 455 “mfcc_compute(mfcc_left, audio_buffer_16bit_left, mfcc_feature_left);” (more precisely, inside this function, at line 263 “float last = (float)audio_data[0] / (1 << 15);”). Can someone tell me how to solve the problem? I’ve declared arrays static to not go into stack overflow. Can someone tell me how to solve the problem? (Int_mic_F7 is the project for NUCLEO F767ZI while audio.zip is the project for NUCLEO H7S3L8)

Hello,

1- How to debug a HardFault on an Arm® Cortex®-M STM32

2- Same code running on a STM32 family but not in the another: did you take into account the memory addresses change/architecture between both products?

  /* set Mfcc DPU to controller */  IDPU * p_dpu = MfccTaskGetDpu((MfccTask_t*)spMfccObj);  AppControllerSetPreprocessDPU((AppController_t*)spControllerObj, p_dpu);

 F767ZI seems dont have DPU inside...

at what line of code should i insert these two suggested lines?
