#define In_Pb6                          GPIO_PB6
#define PB6_FUNC                        AS_GPIO
#define PB6_INPUT_ENABLE                1
#define PULL_WAKEUP_SRC_PB6             1     // PM_PIN_PULLUP_1M

void user_init_peripheral(intretention_flag)

{

    gpio_set_interrupt(GPIO_PB6 ,pol_falling);

}

voidgpio_irq(void)
{
    if((reg_irq_src & FLD_IRQ_GPIO_EN)==FLD_IRQ_GPIO_EN)
    {
        reg_irq_src |= FLD_IRQ_GPIO_EN;
        mini_printf("Interrupt!! GPIO ");

        if( 0== gpio_read(In_Pb6) )
        {
            mini_printf("PB6!! \n");
        }
        else
        {
            mini_printf("Other \n");
        }
    }
}

_attribute_ram_code_void irq_handler(void)

{

    gpio_irq();

}

I set it up to use GPIO Interrupt as above.
However, interrupts are not occurring properly in irq_handler. Is there a problem with the code above?
