Function Documentation

bsp_idle_thread()

void * bsp_idle_thread

(

uintptr_t

ignored

)

Optimized idle task.

This BSP provides its own IDLE thread to override the RTEMS 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>

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

Optimized idle task.

The MSR[POW] bit is set to put the CPU into the low power mode defined in HID0. HID0 is set during starup in start.S.

set_vector()

rtems_isr_entry set_vector	(	rtems_isr_entry	handler,
		rtems_vector_number	vector,
		int	type
	)

Install an interrupt handler.

This method installs an interrupt handle.

Parameters

[in]	handler	is the isr routine
[in]	vector	is the vector number
[in]	type	indicates whether RTEMS or RAW intr

Returns

returns old vector
