MQX Lite Initialization Structure

The MQX Lite initialization structure defines parameters of the application and target hardware.

typedef struct mqxlite_initialization_struct
{
    _mqx_uint           PROCESSOR_NUMBER;
    pointer             START_OF_KERNEL_MEMORY;
    pointer             END_OF_KERNEL_MEMORY;
    _mqx_uint           MQX_HARDWARE_INTERRUPT_LEVEL_MAX;
    _mem_size           INTERRUPT_STACK_SIZE;
    pointer             INTERRUPT_STACK_LOCATION;
    _mem_size           IDLE_TASK_STACK_SIZE;
    pointer             IDLE_TASK_STACK_LOCATION;
    TASK_TEMPLATE_STRUCT_PTR    TASK_TEMPLATE_LIST;
} MQXLITE_INITIALIZATION_STRUCT, * MQXLITE_INITIALIZATION_STRUCT_PTR;

For a description of each field, see the Freescale MQX™ Lite RTOS Reference Manual (MQXLITERM).

The MQX Lite initialization structure is generated automatically by the PEx based on the MQX Lite component settings and can be found in the Generated_Code\<MQXLiteComponentName>.c (for example, MQX1.c) file. This is an example of the initialization structure:

/* MQX Lite initialization structure */
const MQXLITE_INITIALIZATION_STRUCT  MQX_init_struct =
{
/* PROCESSOR NUMBER                 */  1,
/* START OF KERNEL MEMORY           */  __KERNEL_DATA_START,
/* END OF KERNEL MEMORY             */  __KERNEL_DATA_END,
/* MQX_HARDWARE_INTERRUPT_LEVEL_MAX */  1,
/* INTERRUPT STACK SIZE             */  sizeof(mqx_interrupt_stack),
/* INTERRUPT STACK LOCATION         */  mqx_interrupt_stack,
/* IDLE_TASK STACK SIZE             */  sizeof(mqx_idle_task_stack),
/* IDLE_TASK STACK_LOCATION         */  mqx_idle_task_stack,
/* TASK TEMPLATE LIST               */  (TASK_TEMPLATE_STRUCT_PTR)&MQX_template_list[0]
};
