Rubik Pi 3 QCS6490: Is ADSP AudioReach custom CAPI module development supported?

Canonical Ubuntu
1

Hi Rubik Pi / Thundercomm team,

I am a developer working on audio DSP experiments with the Rubik Pi 3 / QCS6490 platform.

I am trying to evaluate whether it is possible to add a custom AudioReach CAPI module into the ADSP AudioReach/SPF runtime on Rubik Pi 3.

So far, I have done the following:

  • Built a custom AudioReach module based on the open-source audioreach-engine
  • Successfully generated a Hexagon v68 DSP libspf.so
  • Confirmed that the generated libspf.so contains my custom CAPI symbols
  • Generated H2XML / JSON / AMDB metadata for the custom module
  • The custom module ID I am using is 0x0800F001

However, the actual board-side ADSP firmware appears to be loaded from:

qcom/qcs6490/Thundercomm/RubikPi3/adsp.mbn

My current understanding is that this adsp.mbn already contains the ADSP runtime, AudioReach/SPF, AMDB, and built-in CAPI modules such as the factory MSIIR module.

I would like to ask:

  1. Does Rubik Pi 3 provide any official BSP / SDK package that includes the ADSP source tree, such as adsp_proc, AudioReach/SPF integration sources, and ADSP firmware build scripts?

  2. Is it possible for developers to rebuild or customize the Rubik Pi 3 ADSP firmware image, especially:

qcom/qcs6490/Thundercomm/RubikPi3/adsp.mbn

  1. Is there an official way to add a custom AudioReach CAPI module into the ADSP AudioReach/SPF runtime?

  2. Should such a module be built statically into adsp.mbn, or is dynamic CAPI module loading supported on Rubik Pi 3?

  3. Is AudioReach Creator / ARC / QACT available for custom module registration on this platform?

  4. Are there any firmware packaging, test-signing, or signing requirements for loading a developer-built ADSP firmware image on Rubik Pi 3?

  5. If ADSP custom module development requires NDA, licensed developer access, or a partner program, could you please point me to the correct contact channel?

My goal is not to modify Linux user-space FastRPC libraries. I am specifically trying to understand whether a custom AudioReach CAPI module can be added to the ADSP AudioReach graph and executed on the QCS6490 ADSP.

Any guidance, documentation, or recommended development path would be greatly appreciated.

Thanks!
