Precompiled CMSIS-DSP library (.a file) for LPC55S69 EVK

[Norihiro]

Hello, 

To compare the performance of mathematical processing between CM33 and PowerQuad, 

I'm looking for CMSIS-DSP precompiled library file(.a) can be used in MCUXpresso for LPC55S69EVK, 

But I can't find it anywhere. It is not included in SDK generated by MCUbuilder site.

I need to build the library from CMSIS DSP source code?

Regards,

If you want to call the CMSIS-DSP function based on CM33 based on LPC5569, you can not import an SDK example, but you can follow up the  procedure, the condition is that you have dragged the LPC55S69 SDK package to the Installed SDKs:

1)Create a new project by clicking New->Create a new C/C++ Project
