CMSIS DSP 1.10.0 release libraries

NewtoM

Dear All,

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

    Dear All,

    in the meantime I managed to understand that I needed to build the library with appropriate settings to yield arm_cortex_math_v7em_fpv4_sp_d16_hard_t_le_eabi.a, which now also works flawlessly on the nRF52840 platform.

    Best regards,
    Tamas
