I am using Freertos on a Intel Galileo Gen 2 board and I am having problems to launch a task. I have a reduced version of the demo main.c just eliminating the references to the demos. I have correctly compiled an run different functions but when I try to launch a Task, as described in the documentation I see no sign of it actually running. This is the code I am testing:
~~~
void frogaTask (void *pvParameters ){
( void ) pvParameters;
g_printf("GET IN");
for ( ;; ){
g_printf("LOOP");
}
vTaskDelete( NULL );
}
int main( void )
{
/* Optionally wait for a debugger to connect. */
prvLoopToWaitForDebugConnection();
/* Init the UART, GPIO, etc. */
prvSetupHardware();
g_printf("1");
BaseType_t ret = xTaskCreate( frogaTask, "Froga" , configMINIMAL_STACK_SIZE , NULL, tskIDLE_PRIORITY + 1, NULL );
g_printf("2");
/* Start the tasks and timer running. */
vTaskStartScheduler();
g_printf("3");
return 0;
}
~~~
When I run it i see nothing on the teminal but the 1 and 2 numbers. This means that Task is actually created (I have checked that ret has a 1 value, what I understand is a correct output) and Scheduler runs and never returns control, what I think is correct, but I don't see the "GET IN" and "LOOP" messages.
What I am missing? How can I get some visibility of what is going on?
Thanks
If you stop the debugger, what code is executing? Could you be in an assert() (ensure configASSERT() is defined), or in a stack overflow hook (ensure stack overflow checking is set to 2).
What happens if you toggle an LED instead of calling g_printf() in the task? Use a delay so you can see the LED toggling, something like:
~~~
for( ;; )
{
ToggleLED(); /* whatever the function is really called).
vTaskDelay( pdMSTOTICKS( 500 );
}
