I am using tm4c123gh6pm for my projects. but from the moment I received the board, the blue LED is always ON. In debug mode, i thought of seeing the GPIO funtionality of the GPIO_PORTF_DATA_R register,through which we turn on the LED blue. But iam not able to since I am getting a series of errors mentioned below. If possible someone help me out in this issue.CORTEX_M4_0: Trouble Reading Memory Block at 0x400253fc on Page 0 of Length 0x4: Debug Port error occurred.
