I am doing audio signal processing on an nRF52840 (Arm Cortex M4f) platform. I am using precompiled CMSIS DSP libraries (specifically, libarm_cortexM4lf_math.a), which were shipped with the nRF5 SDK. Based on arm_math.h, the CMSIS DSP version is V1.6.0 and dated 18. March 2019.
In the meantime there is a version 1.10.0, which provides new functionality I'd like to use. I found the source code, but, unfortunately, I can neither find a precompiled library, nor am I able to build it on my own.
So my question is: is there a repository, where I can get the precompiled libarm_cortexM4lf_math.a for CMSIS DSP v1.10.0?
Thanks in advance,Tamas
