xt-ld.exe cannot find CMSIS DSP library

aravindt

Platform: iMXRT500

SDK: SDK_2_11_1_EVK-MIMXRT595

Xtensa Xplorer IDE version: 8.0.15 Windows

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:

Library search path is correct. But then, I still see this linker error:

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

Please help.

Thank you,
Aravind.

  • Hi,

    I was linking the wrong library. My objective is to run FFT on DSP instead of 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,

    Aravind.
