Hello guys. I make speech recognition on STM32F407GV Discovery. Digital microphone have got in this device. Program in the Error Speech recognition.

Error file : feature.hpp

Error Codes : 

    ret = processing::stack_frames(
        &stack_frame_info,
        sampling_frequency,
        frame_length,
        frame_stride,
        false
    );

Program is go to this line on error. Program error than jump to HardFault_Handler interrupt.

Help me please.

Did you port the Edge Impulse exported library to the STM32F407? Often, I find the "hard fault" results from trying to run code on the wrong target microcontroller. The STM32 demos in this repo will only work on the L476RG and the L432KC.

Thank you, I know dude.

@elimsjxr Please open a new issue, as what your describing is not relevant to this thread. In that new issue, please repost your question and answer the following: have you tried one of the demo programs on a known good board (e.g. STM32 Nucleo-L476RG)?
