Hello,

How did you generate the code? With CubeMx?

To give better visibility on the answered topics, please click on "Accept as Solution" on the reply which solved your issue or answered your question.

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.

https://github.com/FreeRTOS/FreeRTOS-Kernel/blob/30afc1a2c05157fcac1a46dc773b0125bd680b82/tasks.c#L8578

Haithem.
