Wakeup from an GPIO interrupt not working

Hello Support

 

I have LPC 54102 board with me and I have tested MCU_Power_Profile. It works fine.

When I press button it comes out of the sleep.

But now when I used the same example to wake up via a GPIO pin it does not work. The ISR is not called.

If I test the interrupt pin separately it works fine.

So no problem in the interrupt configuration.

Can you please tell me if there is any example where the MCU wakes up from an interrupt on GPIO?
