Hi
I was Downloaded LPC1788 CMSIS and use GPIO Interrupt Project and run keil Debugger.
Problem is that GPIO Handler Never Call.
NVIC_SetPriority(GPIO_IRQn, 1);
NVIC_EnableIRQ(GPIO_IRQn);
GPIO_IntCmd(2, 1<<9, 1);
but with Software Trriger, GPIO Handler called :
NVIC->STIR = GPIO_IRQn;

I have used GPIO interrupt with the following code:

LPC_IOCON->P2_9 = 0x30; // Setup P2.9 as Input with Hysterese

// Interrupts for Rising AND falling edge

LPC_GPIOINT->IO2IntEnR = (1 << 9);

LPC_GPIOINT->IO2IntEnF = (1 << 9);

// Enable Interrupt
NVIC_EnableIRQ(GPIO_IRQn);

void __attribute__ ((interrupt)) GPIO_IRQHandler(void)
{
// do something

// Reset all Interrupt Flags

LPC_GPIOINT->IO0IntClr = 0xFFFFFFFF;
LPC_GPIOINT->IO2IntClr = 0xFFFFFFFF;
}
