Hello,

How did you generate the code? With CubeMx?

Complaining you have two instances of the function, or source for it, check your project trees.

Where it lacks for a definition/prototype, make sure you're including a .H that does so in the source file that's USING it.

Hi @Kai_Satone 

it seems that you are setting the configKERNEL_PROVIDED_STATIC_MEMORY to 1 in your FreeRTOSConfig.h file

if it is the case then please unset it. It is clearly stated in FreeRTOS comments below.
