IMX8MP hifi4 dsp codec library

[jiada]

Hello NXP support team

We are evaluating hifi4 dsp on iMX8MP, so far we are able to compile DSP framework, unit-test, from imx-audio-framework , and confirmed hifi4 dsp can be started/stopped via sysfs interface

But executing of unit-test failed with error message

By looking at unit-test source code and  i.MX DSP User's Guide (nxp.com) 

I think this is because I am missing DSP codec and DSP codec wrapper libraries,
which needs authorization from NXP marketing or can be downloaded from yocto mirror server
(but so far I am not able to find where to download)

Could you please provide us required DSP codec and codec wrapper libraries
or let us know where to download?

DSP codec & wrapper library: (need authorization from NXP marketing)

According to the i.MX DSP User's Guide documentation our problem was solved, thank you very much。

I have already  mailed to you, pls check the mail

Hi @joanxie , Can you also send me a copy of the NXP's codec library ? I am stuck in the similar fashion. I could not locate the libraries or the Yocto mirror site. My platform is also a iMX8 MP EVK.

Thankyou

[joanxie]

pls create a new case for your request

Hi @joanxie
I have already resolved the previous issue, but now I want to integrate our own audio codec library because the desired codec protocol is not available. How can we integrate our own audio codec library into the DSP?

[joanxie]

if you still have issue about this, pls create a new case for this, and uploaded detailed your use case information

Hi @joanxie 

I have mailed to you, pls check

Thanks.
