    HI Yash,

    GPIO227 is an AGPIO. Meaning it can have either digital or analog functionality. When using an AGPIO pin  you must set the analog mode as disabled using the following function:

    GPIO_setAnalogMode(227, GPIO_ANALOG_DISABLED)

    Or writing to the corresponding AGPIOCTRLH register.

    You also need to configure your GPIO as an output using the GPHDIR register.

    Thank you,

    Luke
