Access to the CMSIS library functions

[gkosteva]

Hi,

I'm using the IMXRT1064 evaluation kit on version MCUXpressoIDE_win_11.3.1_5262. The SDK version is SDK_2_9_2_EVK-MIMXRT1064. I do not see any math.a files in the SDK for the CMSIS functions.

There is a 2016 technical note here: https://community.nxp.com/t5/Kinetis-Design-Studio-Knowledge/Adding-CMSIS-DSP-Library-to-a-KSDK-2-x-...  which describes adding the CMSIS-DSP library located at "SDK...\CMSIS\DSP_Lib\Source\...". However, the CMSIS folder in SDK_2_9_2_EVK-MIMXRT1064 does not contain any of these CMSIS subfolders.

Would you know the pathname to access the CMSIS library of math functions for the IMXRT1064?      Do I need to use a different SDK?

Thanks!

Hi,

You can find math.a library in this path: SDKPackage\CMSIS\DSP\Lib\GCC I checked using latest SDK version (2.10.0). Also you can find a more updated version of the document you are referring using MCUXpresso IDE and SDK in the link below.

Hope it helps.

Have a great day,

Felipe
