[i.MXRT595] Could not link CMSIS DSP library in DSP application

[aravind_t]

Platform: iMXRT595

SDK: SDK_2_11_1_EVK-MIMXRT595

Xtensa Xplorer IDE version: 8.0.15 Windows

DSP application: Hello world

I am trying to link SDK_2_11_1_EVK-MIMXRT595\CMSIS\DSP\Lib\GCC\libarm_ARMv8MMLldfsp_math.a to a DSP application. For this, in Xplorer IDE, I set the following:

C:/usr/xtensa/XtDevTools/install/tools/RI-2020.5-win32/XtensaTools/bin/xt-ld.exe: cannot find libarm_ARMv8MMLldfsp_math.a
make[1]: *** [dsp_hello_world_usart_fusionf1] Error 2

I posted the same in Cadence forum.
https://community.cadence.com/cadence_technology_forums/f/digital-implementation/57028/xt-ld-exe-can...

Please help.

Thank you,

Aravind.

Hi @aravind_t,

As this is an issue you are experiencing specifically Xtensa Xplorer IDE (a third part) and not because of our library or SDK, I believe the best support would come from the cadence forum rather than this one. Please continue your inquiry on the cadence post you attacked.

Thank you for your understanding,

Edwin.

Hi Edwin,

I was linking the wrong library. My objective is to run FFT on DSP without using PowerQuad.

I learned that this could be done through NatureDSP library and I was able to run naturedsp stock example:
SDK_2_11_1_EVK-MIMXRT595\boards\evkmimxrt595\dsp_examples\naturedsp

Library link issue is not relevant anymore. Thank you for the support.
