AcousticBF initialization not working on STM32H7

[AAMAN.1]

Hi,

I'm trying to setup the SMARTMIC package on my STM32H743 board with the CCAO2M2 board and MEMS microphones, and I want to use the beamforming library (AcousticBF version V2.2.0).

But when i call the BF_init function, I pass in the HardFault_Handler function at the AcousticBF_setConfig function call.

I've tested many things and i noticed that when I comment the SIDE_X line (SIDE_X = 147) we don't pass anymore in the HardFault_Handler function.

I have the same problem when i call the AcousticBF_FirstStep function : even if I comment the SIDE_X line in my initilization, I still pass in the HardFault_Handler function.

 

What could explain this behavior ?

Thank you for your help.

Hello @AAMAN.1​ and welcome to the STM32 Community :)

You are using the AcousticBF library version V2.2.0.

I advise you to update and use the latest release of AcousticBF library (v2.2.1) within the latest version of SMARTMIC package published on ST web site.

This may help solving your issue.

Please try it and let me know if it is ok with the latest release.

@Imen DAHMEN​ Hi, Thank you for your help.

I think this version is not publicly available yet, because on ST web site there is the 2.2.0 and 2.0.0 version and not the 2.2.1.

But maybe I'm looking in the wrong place.

Hi @AAMAN.1​ ,

In your initial post, you mentioned that you are using AcousticBF library (version V2.2.0).

But the latest release of FP-AUD-SMARTMIC1(v 2.2.0) available in the ST web site is updated with AcousticBF library V2.2.1 / 03-Apr-2020, and it's recommended to use this latest release that contains enhancements and fixes.

Please keep me updated.

@Imen DAHMEN​ Hi and thank you for your reply.

Since the beginning, i'm using the SMARTMIC version 2.2.0 with the AcouticBF library version 2.2.0 and the problem still there.

However the use of this library is not a problem with de SMARTMIC package on the STM32F446 board but there is a problem when I use it with the STM32H743 board.

@Imen DAHMEN​ I'm sorry but with this link :

https://www.st.com/en/embedded-software/fp-aud-smartmic1.html

I downloaded the latest version of the SMARTMIC package (2.2.0) but the version in the AcousticBF library still 2.2.0 even if in the release note of the library it's clearly marked that it was updated on 03-Apr-2020.

Hi @AAMAN.1​ ,

Sorry for the delayed reply on this, but I was waiting our team for the new version of the AcousticBF library which fix the issue.

As this request is also received via Online-support, our FAE will provide you the library to check the patched version with your full HW setup.

Thanks for your contribution.
