Dear,

I have some problems with Deep Sleep mode.
The problem is about LM3S5T36 is taking to much power: about 6.674mA at deesleep mode.
I'm using Code sourcery compiler and StellarisWere library. Here is simple code which should put the device in deep sleep mode:

void main()
{
//
// Set the clocking to run directly from the external crystal/oscillator.
// TODO: The SYSCTL_XTAL_ value must be changed to match the value of the
// crystal on your board.
//
SysCtlClockSet(SYSCTL_SYSDIV_1 | SYSCTL_USE_OSC | SYSCTL_OSC_MAIN |
SYSCTL_XTAL_16MHZ);

SysCtlPeripheralPowerOff(SYSCTL_PERIPH_GPIOA);
SysCtlPeripheralPowerOff(SYSCTL_PERIPH_GPIOC);
SysCtlPeripheralPowerOff(SYSCTL_PERIPH_GPIOD);
SysCtlPeripheralPowerOff(SYSCTL_PERIPH_GPIOE);
SysCtlPeripheralPowerOff(SYSCTL_PERIPH_I2C0);
SysCtlPeripheralPowerOff(SYSCTL_PERIPH_I2C1);
SysCtlPeripheralPowerOff(SYSCTL_PERIPH_PWM0);
SysCtlPeripheralPowerOff(SYSCTL_PERIPH_CAN0);
SysCtlPeripheralPowerOff(SYSCTL_PERIPH_UART0);
SysCtlPeripheralPowerOff(SYSCTL_PERIPH_UART1);
SysCtlPeripheralPowerOff(SYSCTL_PERIPH_UART2);
SysCtlPeripheralPowerOff(SYSCTL_PERIPH_SSI0);
SysCtlPeripheralPowerOff(SYSCTL_PERIPH_SSI1);
SysCtlPeripheralPowerOff(SYSCTL_PERIPH_USB0);

SysCtlPeripheralEnable(SYSCTL_PERIPH_GPIOB);

GPIOPinTypeGPIOInput (GPIO_PORTB_BASE, GPIO_PIN_7);
GPIOIntTypeSet(GPIO_PORTB_BASE, GPIO_PIN_7, GPIO_HIGH_LEVEL);
GPIOPinIntEnable(GPIO_PORTB_BASE, GPIO_PIN_7);
IntEnable(INT_GPIOB);
IntMasterEnable();

SysCtlPeripheralClockGating(true);
// Shutdown the USB PHY
HWREG(0x40050001) = 0x21;
SysCtlPeripheralDeepSleepEnable(SYSCTL_PERIPH_GPIOB);

SysCtlDeepSleepClockSet(0x00000030); // use INT_30K
SysCtlDelay(500000);
SysCtlDeepSleep();

while(1)
{
SysCtlDelay(50000);
}
}

   Does  anyone meet the power problem at the deepsleep mode ?

    thanks!
