◆ 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.

◆ console_inbyte_nonblocking()

int console_inbyte_nonblocking ( int  port)

This method polls the specified port for an input character. console port.

Parameters
[in]portis the input port
Returns
This method returns the character read of -1 if there is no data.

◆ 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]handleris the isr routine
[in]vectoris the vector number
[in]typeindicates whether RTEMS or RAW intr
Returns
returns old vector
