Hello, I am using linux kernel 2.6.30. I am trying to set interrupt type like Falling edge or Rising edge to my GPIO. I am using the following calls: set_irq_type(irq_num, IRQ_TYPE_EDGE_RISING) // here irq_num is 50 for gpio 6 in DM355 But, the value in GPIO register SET_RIS_TRIG is not set. So, my interrupt service route was never called even though my gpio interrupt is registered successfully.
But, if I directly set the value in this SET_RIS_TRIG register for my gpio 6, the interrupt is raised and my ISR is been called. My questions are: 1) If set_irq_type is the right API I should call to set irq type for gpio? 2) If yes, what I am missing? 3) If no, what is the right API I should use to set irq type for gpio? Thanks, Yan
