The vendor-specific definitions, which are required for FreeRTOS, are the following:
FreeRTOSConfig.h
#define configCPU_CLOCK_HZ ( SystemCoreClock ) #define configPRIO_BITS __NVIC_PRIO_BITS /* Definitions that map the FreeRTOS port interrupt handlers to their CMSIS standard names. */ #define xPortPendSVHandler PendSV_Handler #define vPortSVCHandler SVC_Handler #define xPortSysTickHandler SysTick_Handler
