Problem Description

I've tried to search for the function that cause the problem (vApplicationGetTimerTaskMemory) But i only found an extern vApplicationGetTimerTaskMemory. in timer.c

NVM, I've just read the comment

    /* If static allocation is supported then the application must provide the
    following callback function - which enables the application to optionally
    provide the memory that will be used by the timer task as the task's stack
    and TCB. */
