AM68A: INMP441 integration with AM68A

Rishad KP

Part Number: AM68A
Other Parts Discussed in Thread: SK-AM68, AM68

Tool/software:

Dear TI team,

1) I'm trying to integrate 4 INMP441 microphone with I2S interface with SK-AM68 development board. As the best of my knowledge it needs device tree changes to work with this microphone. Could you guys help me with a Guide or documentation that could help me with dtsi files and integration of the microphone?

2) While approaching this on my own I couldn't get my build complete (using yocto-build) as my system crashes while trying to build. Is there any system requirements other than the 250 GB of free space to accomplish the build?

Hello Rishad,

The audio support/McASP driver for AM68 is still unavailable as part of the latest SDK 9.2 on ti.com. The current plan is to have the driver support as part of the 10.1 release at the end of this year.

For building Yocto, suggest referring to the FAQ - https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1281833/faq-processor-sdk-j784s4-how-do-i-build-yocto-images-and-packages-for-j7-devices This applies to AM68 as well.

Thanks.

Also is there any native code through which we can integrate and implement this microphone with am68 like stm32 has HAL library is there any such way from TI? We've committed this with our customer from australia so if there is no way we can implement this on Am68 we've to switch Nvidia to implement the same. Hope to get a swift reply from you guys.

Can you share more details on what USB device you use as a microphone? Based on that, we suggest looking into the USB audio class driver to see if there is support for it as part of the Linux kernel documentation.

No, we don't have such HAL library code. As previously noted, the 10.1 SDK would have this feature available as part of the PSDK Linux release.

Thanks.
