I tested the following project in FRDM-k64F.
/* MQX task IDs */
#define KTEST1_TASK 1U
#define CANADA_TASK 2U
#define WORLD_TASK 3U
/* MQX task stack sizes */
#define KTEST1_TASK_STACK_SIZE 1024
const TASK_TEMPLATE_STRUCT MQX_template_list[] =
{
/* Task: Ktest1 */
{
/* Task number */ KTEST1_TASK,
/* Entry point */ (TASK_FPTR)Ktest1_task,
/* Stack size */ KTEST1_TASK_STACK_SIZE,
/* Task priority */ 8U,
/* Task name */ "ktest1",
/* Task attributes */ (MQX_AUTO_START_TASK),
/* Task parameter */ (uint32_t)(0),
/* Task time slice */ (uint32_t)(0)
},
/* Task: CANADA */
{
/* Task number */ CANADA_TASK,
/* Entry point */ (TASK_FPTR)Canada_task,
/* Stack size */ KTEST1_TASK_STACK_SIZE,
/* Task priority */ 8U,
/* Task name */ "Canada",
/* Task attributes */ (MQX_TIME_SLICE_TASK),
/* Task parameter */ (uint32_t)(0),
/* Task time slice */ (uint32_t)(100)
},
/* Task: WORLD */
{
/* Task number */ WORLD_TASK,
/* Entry point */ (TASK_FPTR)World_task,
/* Stack size */ KTEST1_TASK_STACK_SIZE,
/* Task priority */ 8U,
/* Task name */ "World",
/* Task attributes */ (MQX_TIME_SLICE_TASK),
/* Task parameter */ (uint32_t)(0),
/* Task time slice */ (uint32_t)(100)
},
TASK_TEMPLATE_LIST_END
};
void Ktest1_task(uint32_t task_init_data)
{
_task_id ktest1child;
ktest1child = _task_create(0, CANADA_TASK, 0);
if(ktest1child==MQX_NULL_TASK_ID)
{
printf("\nFailed to create task Canada\n");
}
else
printf("\nSuccess to create task Canada\n");
ktest1child = _task_create(0, WORLD_TASK, 0);
if(ktest1child==MQX_NULL_TASK_ID)
printf("\nfailed to create task World\n");
else
printf("\nsuccess to create task World\n");
_task_block();
}
void Canada_task(uint32_t task_init_data)
{
int counter = 0;
printf("\nHellow Canada\n");
while(1) {
counter++;
/* Write your code here ... */
}
}
void World_task(uint32_t task_init_data)
{
int counter = 0;
printf("\nHellow World\n");
while(1) {
counter++;
/* Write your code here ... */
}
}
When I run this project, the status of task ktest1 is blocked. the status of _mqx_init_task is terminating. the status of task Canada is always active, and the status of task World is always ready, even I set the Canada_task as MQX_TIME_SLICE_TASK. It still looks like FIFO Scheduling.
