TM4C123GH6PGE LM4F232H5QD

Other Parts Discussed in Thread: TM4C123GH6PGE

Hi TI experts,

I get receives a fault interrupt.

I"m try use USB0 on my Board TM4C123GH6PGE as is EVM LM4F232H5QD OTG USB Host.

I Set the USB0 and the Port B,F,G,L and set the pin config...

But while I use USBOTGMain() and the USBOTGSessionRequest() function is call I get FaultISR()

Startup.c

//*****************************************************************************
//
// External declaration for the interrupt handler used by the application.
//
//*****************************************************************************
extern void USB0OTGModeIntHandler(void);

........

//*****************************************************************************
//
// The vector table. Note that the proper constructs must be placed on this to
// ensure that it ends up at physical address 0x0000.0000.
//
//*****************************************************************************
__root const uVectorEntry __vector_table[] @ ".intvec" =
{
{ .ulPtr = (unsigned long)pulStack + sizeof(pulStack) },
// The initial stack pointer
ResetISR, // The reset handler
NmiSR, // The NMI handler
FaultISR, // The hard fault handler

.........

USB0OTGModeIntHandler, // USB0

........

App.c

//
// Enable the USB peripheral
//
ROM_SysCtlPeripheralEnable(SYSCTL_PERIPH_USB0);

//
// Configure the required pins for USB operation.
//
ROM_SysCtlPeripheralEnable(SYSCTL_PERIPH_GPIOB);
ROM_SysCtlPeripheralEnable(SYSCTL_PERIPH_GPIOF);
ROM_SysCtlPeripheralEnable(SYSCTL_PERIPH_GPIOG);
ROM_SysCtlPeripheralEnable(SYSCTL_PERIPH_GPIOL);

ROM_GPIOPinConfigure(GPIO_PG4_USB0EPEN);
ROM_GPIOPinTypeUSBDigital(GPIO_PORTG_BASE, GPIO_PIN_4);
ROM_SysCtlPeripheralEnable(SYSCTL_PERIPH_GPIOL);
ROM_GPIOPinTypeUSBAnalog(GPIO_PORTL_BASE, GPIO_PIN_6 | GPIO_PIN_7);
ROM_GPIOPinTypeUSBAnalog(GPIO_PORTB_BASE, GPIO_PIN_0 | GPIO_PIN_1);

USBOTGMain(GetTickms());
