Where are the NatureDSP unit tests?

[abdob]

Hi, 

This DSP User's guide:

https://www.nxp.com/docs/en/user-guide/IMX_DSP_USERS_GUIDE.pdf

refers to the unit_tests in this location:

Unit test location: rootfs: /unit_tests/DSP/naturedsp_test

Where can I find the unit tests? I've tried downloading and extracting the packages in the user guide, but I don't see the unit_tests directory anywhere.

Thanks,
Abdo

firstly download images to your board, then you can find this when board boot up

I was able to extract the rootfs from the I.MX 8M Plus EVK and I.MX 8QuadMax MEK images, I see /unit_tests/DSP directory however it only contains dsp_rend_test.out and dsp_test.out.

I don't have the actual boards but I am attempting to reuse the test vectors for the MIMRT685 EVK which includes the HIFI4 DSP but is not a linux-based board.

Is the content inside naturedsp_test accessible without having the linux-based boards?

the user guide you refer to is for i.mx processor, if you are interested with IMXRT, pls create a new thread and put it in the i.mxRT community, the IMXRT engineer would check this for you, I'm not sure this package is available for imxRT or not

Hi, 

Although I have the i.mxrt board, I am running HIFI4 DSP examples using simulation.

This question is independent of the specific NXP board, I posted the question in this i.MX forum because the document refers to the DSP unit_test which I don't see present in the downloads mentioned.

I would appreciate it if I get any pointers to locate the unit tests.

Thanks,
Abdo
