Part Number: TM4C123GH6PGE
Hi all, I am running a strange problem by running blinky example code on DK-TM4C123G launcher pad. First of all, to avoid confusion, the original example code runs fine on this launcher pad board without any problem, the problem occurs when I changed the GPIO pin to PD7, the my code has a FaultISR error. Can anyone explain what is causing it? Here is my code (without minor alteration on the example project):
"
#include <stdint.h>
#include <stdbool.h>
#include "inc/hw_memmap.h"
#include "driverlib/gpio.h"
#include "driverlib/sysctl.h"
#define TEST_GPIO_PORT GPIO_PORTD_BASE
#define TEST_GPIO_PIN GPIO_PIN_7

//! A very simple example that blinks the on-board LED.
//
//*****************************************************************************
//*****************************************************************************
//
// Blink the on-board LED.
//
//*****************************************************************************
int
main(void)
{
volatile uint32_t ui32Loop;
//
// Enable the GPIO port that is used for the on-board LED.
//
SysCtlPeripheralEnable(SYSCTL_PERIPH_GPIOG);
//
// Check if the peripheral access is enabled.
//
while(!SysCtlPeripheralReady(SYSCTL_PERIPH_GPIOG))
{
}
//
// Enable the GPIO pin for the LED (PG2). Set the direction as output, and
// enable the GPIO pin for digital function.
//
GPIOPinTypeGPIOOutput(TEST_GPIO_PORT, TEST_GPIO_PIN);
//
// Loop forever.
//
while(1)
{
//
// Turn on the LED.
//
GPIOPinWrite(TEST_GPIO_PORT, TEST_GPIO_PIN, TEST_GPIO_PIN);
//
// Delay for a bit.
//
for(ui32Loop = 0; ui32Loop < 200000; ui32Loop++)
{
}
//
// Turn off the LED.
//
GPIOPinWrite(TEST_GPIO_PORT, TEST_GPIO_PIN, 0);
//
// Delay for a bit.
//
for(ui32Loop = 0; ui32Loop < 200000; ui32Loop++)
{
}
}
}

Thanks!
