This is explained here: http://www.freertos.org/a00110.html Priorities are controlled by two macros: - configKERNEL_INTERRUPT_PRIORITY determines the priority of the RTOS daemon task - configMAX_API_CALL_INTERRUPT_PRIORITY dictates the priority of ISRs that make API calls Notes: 1. Interrupts that do not call API functions should be >= configKERNEL_INTERRUPT_PRIORITY and will nest. 2. Interrupts that call API functions must have priority between KERNEL_INTERRUPT_PRIORITY and MAX_API_CALL_INTERRUPT_PRIORITY (inclusive). 3.

See http://www.FreeRTOS.org/RTOS-Cortex-M3-M4.html If you call a FreeRTOS API function from an interrupt with priority higher than MAX_API_CALL_INTERRUPT_PRIORITY FreeRTOS will generate an exception. If you need to call a FreeRTOS API function from your system’s highest priority interrupt you must reduce all interrupt priorities to MAX_API_CALL_INTERRUPT_PRIORITY or lower. If your system pipe (IPC) interrupt priority is less than or equal to MAX_API_CALL_INTERRUPT_PRIORITY then care must be taken with code that writes to flash (including the Flash/BLE/Emulated EEPROM/Bootloader drivers from Cypress PDL). The duration of critical sections must be kept short - see the Configuration Considerations section of the flash driver in the PDL API Reference. */ /* Put KERNEL_INTERRUPT_PRIORITY in top __NVIC_PRIO_BITS bits of CM4 register */ #define configKERNEL_INTERRUPT_PRIORITY 0xFF /* Put MAX_SYSCALL_INTERRUPT_PRIORITY in top __NVIC_PRIO_BITS bits of CM4 register NOTE For IAR compiler make sure that changes of this macro is reflected in file portable\IAR\CM4F\portasm.s in PendSV_Handler: routine */ #define configMAX_SYSCALL_INTERRUPT_PRIORITY 0x3F /* configMAX_API_CALL_INTERRUPT_PRIORITY is a new name for configMAX_SYSCALL_INTERRUPT_PRIORITY that is used by newer ports only.
