FaultIsr() on Master M3 of F28M35

Hello,

Unfortunately, when my program is running FaultIsr() interrupt is triggered.

1 - Where can I find information(documentation) to get the cause of this ISR ?

2 -I use uart. I noticed that this interruption is triggered from the moment the uart receives data.

   Here is the sample code of the Uart

//Initialization

#ifdef UART0

// Configure the GPIO settings for the UART0 pins. This function also gives
// control of these pins to the UART0 hardware. Consult the data sheet to
// see which functions are allocated per pin.
// The pins are assigned as follows:
GPIOPinTypeUART(GPIO_PORTJ_BASE, GPIO_PIN_3); 
GPIOPinTypeUART(GPIO_PORTJ_BASE, GPIO_PIN_2); 

// Configure the pin muxing for UART0 functions 
GPIOPinConfigure(GPIO_PJ3_U0RX); 
GPIOPinConfigure(GPIO_PJ2_U0TX); 

//PULL UP
GPIOPadConfigSet(GPIO_PORTJ_BASE,GPIO_PIN_3,GPIO_PIN_TYPE_STD_WPU);//push pull with weak pull up 
GPIOPadConfigSet(GPIO_PORTJ_BASE,GPIO_PIN_2,GPIO_PIN_TYPE_STD_WPU);//push pull with weak pull up 

// 8 bits, 1 bit de stop, pas de bit de parité, en 9600 bauds
UARTConfigSetExpClk(UART0_BASE, SysCtlClockGet(SYSTEM_CLOCK_SPEED), 9600, //(JPP)
(UART_CONFIG_WLEN_8 | UART_CONFIG_STOP_ONE |
UART_CONFIG_PAR_NONE));

// Enable the UART interrupt.
IntRegister(INT_UART0, UARTIntHandler); 
IntEnable(INT_UART0); 
UARTIntEnable(UART0_BASE, UART_INT_RX | UART_INT_RT/*| UART_INT_TX */); 

#endif

(...)

//Interrupt

void UARTIntHandler(void) 
{

(...)

unsigned long ulStatus;
// Get the interrrupt status.
ulStatus = UARTIntStatus(UART0_BASE, true);
// Clear the asserted interrupts.
UARTIntClear(UART0_BASE, ulStatus);

(...)

}
