I am trying to use a GPIO as interrupt in Cortex M4 of i.MX7. For that I refer the example driver application “gpio_imx” provided in freeRtos code."I understood the entire code but one thing i am not able to track is the interrupt handler BOARD_GPIO_KEY_HANDLER that is defined as macro in board.h file as GPIO2_INT31_16_Handler. but where does this GPIO2_INT31_16_Handler defined.
Example code is building successfully.
