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

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
