Can't find CMSIS/lib while try to use CMSIS-DSP

polarwang · ‎2025-07-23

I am using stm32f407 in stm32cubeide. When I tried to follow the steps in the forum to access the DSP library, I found that there was no CMSIS/lib in my firmware package. Neither in both firmware package follows.

This is my screenshot in: C:\Users\dingh\STM32Cube\Repository\STM32Cube_FW_F4_V1.28.2\Drivers\CMSIS

In the relevant posts I found on the forum, there should be a lib folder in this folder. I‘m trying to link the dsp static library. Any idea how to find this folder？

Weird, it appears to be missing for the STM32F4.

Download a different Cortex-M4 chip library such as STM32L4. They're in there.

Hello @polarwang and welcome to the community,

Since CMSIS V 5.8.0, the CMSIS-DSP libraries are supplied as an individual package.

Before you get started, open the ARM.CMSIS.pdsc file in \STM32Cube_FW_xx_Vx.x.x\Drivers\CMSIS folder with notepad to know which CMSIS version is included in the package.

The CMSIS V5.9.0 version is integrated in STM32Cube_FW_F4_V1.28.2.

I recommend you to follow the steps shared in How to integrate CMSIS-DSP libraries on a STM32 project FAQ to integrate the DSP libraries in your project when using STM32CubeIDE toolchain. This FAQ provides an example based on the STM32CubeF4 package version 1.28.0.

I hope this help you.

Thank you.
