xt-ld.exe cannot find CMSIS DSP library

aravindt over 2 years ago

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 Aravind,

I was wondering if you actually found the CMSIS DSP sources for Xtensa DSPs? The only sources I can find are the NatureDSP ones.

Thank you,

Volodymyr

Hi Volodymyr,

Thank you for your response.
I was trying to link the wrong library. Yes, I am using NatureDSP library to exercise FFT functions.

Please close this issue.
Best regards,

Aravind.
