Trying get started with Allwinner SoC-Only 3-Mic Far-Field Dev Kit for Amazon AVS

BPI IoT module Allwinner SoC-3-Mic Far-Field (BPI-R18-AVS)
1

I’m trying to start using this kit and it’s becoming impossible for me. Basically I have flashed the lasted image “tina_tulip-noma_card0 2018-05-17.img”

But when i try to start sampleApp, an error occurred:

Could someone help me with this error?

The banana support pi doesn’t help. They don’t have updated documentation. No images since 2018. There is nothing.

PS: For now, I advise not to buy this kit. There is no support or updated information.

All the information is on WiKi, http://wiki.banana-pi.org/BPI-R18-AI(Allwinner_SoC-Only_3-Mic_Far-Field_Dev_Kit), your feedback was updated on it. As for the schematics and BSP, please write to [email protected], NDA is needed for those documents.

Hi Hi,

I have tested the last image you send me and now Alexa SampleApp works.

Now I have some questions:

  • Using Tina Linux (Last Image), I have sound only on jack connector, but not in speakers connectors (TAS5731M). How I can solve it?

  • Using Ubuntu mate image, I have no audio at all. No Audio in speakers (TAS5731M). No Audio in headphones jack.

  • The development kit includes seven jumpers connectors but I don’t know for what.

Thanks.

Im trying again to start the launch sampleapp and now I always get “Segmentation fault”:

I think that I know what happens. The license of TUTUCLEAR is expired in this image because if I start just after connect to the internet (before the device date is syncronized from the internet) the SampleApp starts. So the question is. How Can I avoid this. I am searching about TUTUCLEAR but nothing appears on the internet. There are some alternative software? What I can do?

Thanks.
