void * bsp_idle_thread

(

uintptr_t

ignored

)

This BSP provides its own IDLE thread to override the RTEMS one.

Optimized idle task.

So we prototype it and define the constant confdefs.h expects to configure a BSP specific one.

This idle task sets the power mode to idle. This causes the processor clock to be stopped, while on-chip peripherals remain active. Any enabled interrupt from a peripheral or an external interrupt source will cause the processor to resume execution.

To enable the idle task use the following in the system configuration:

#include <bsp.h>
 
#define CONFIGURE_INIT
 
#define CONFIGURE_IDLE_TASK_BODY bsp_idle_thread
 
#include <confdefs.h>
