Compilation audio server

[benjamin_beck]

Hi,

I have an iMX8M-EVK board and I am trying to reproduce what has be explain in the following document:

Implement Low-Power Audio on i.MX8M  -  Document Number AN12195

I am in the part "Build Cortex-M4 core application" and some files are missing.

I use:

-IAR Embedded Workbench IDE - Arm 8.32.1

-MCUXpresso SDK :    SDK_2.3.0_EVK-MIMX8MQ

The missing files are:

fsl_shell.c

fsl_shell.h

fsl_sdma.c

fsl_sdma.h

fsl_sai_sdma.h

fsl_sai_sdma.c

I can found the fsl_shell.c and fsl_shell.h files on github but then I am not sure if the version is ok.

I can't find the other missing files.

Does anyone know where to found these files ? Is a MCUXpresso SDK version containing these files ?

Thanks you very much

 Hello all

Please guide I am also following the "Low-Power Audio on i.MX8M - Document Number AN12195" but facing issues in doing so of missing files. I am using IMX8M EvK and Linux version is 5.4

Linux imx8mqevk 5.4.70-2.3.2+g5f2220e87dd8 #1 SMP PREEMPT Wed Sep 29 07:46:26 UTC 2021 aarch64 aarch64 aarch64 GNU/Linux

Hello,

Which kernel version are you using?

Best Regards,

Hi,

Do you try to compile and run the low power audio app?

I use the version 4.9.51_imx8m_ga. But I can't get the imx_rpmsg_char and the rmtcore-shm driver working so that I am not sure it is the correct one.

Best regards,

Benjamin

I will start building the audio app for the Linux version that specifies the document that is L4.9.58

I will notify you any update.

Best Regards,

Diego.
