STM32CubeIDE: fatal error: core_cm4.h: No such file or directory

[MM1]

Hi there,

I am having trouble with CubeIDE: When building my project i get the following error:

"fatal error: core_cm4.h: No such file or directory"

I am using:

• MCSDK 5.Y.1
• STM32CubeMX
• STM32CubeIDE 1.6.1
• STM32F302R8 NucleoBoard
• X-NUCLEO-IHM07M1 motor driver
• SPI-Sensor
• two external buttons

What I did to get to this point:

• Generated the project via MotorControl Workbench and CubeMX --> project is for a Motor Control application
• Modified the project with CubeMX: added few GPIO Inputs and Outputs, added a Timer (TIM16) and SPI2
• Added the Project to the CubeIDE workspace
• added some own Code
• hit build
• got the error: "fatal error: core_cm4.h: No such file or directory"
• tried to add the include path manually --> did not work

Hope someone can help me on this

Greetings MM1

Hello @MM1​ ,

It seems the include paths are not properly set up.

Please make sure to configure the include paths and check the path of the core_cm4.h header file. Maybe that folder was not in the include folder list.

Hi Imen,

Thanks for the reply. I double checked the include paths and the path to the core_cm4.h was indeed missing.

It is just sad that you have to do it manually sometimes when using the Toolchain MotorControl Workbench/CubeMX (happened to me before)

hi, I know it has been a year ago, but may I know how to include the path? i mean how to find the path library and put it in the path?

Are you unable of finding files on your PC and using the internet?
