STM32L1 and low power stop mode

Hi,

 

I am using a stm32l1 on the STM32L152c-discovery and trying to reach a lower power consumption.

But I can't reach less than 0.6mA !!! (10x more than in theory).

Where this current is going?

Any idea?

 

HAL_Init();
HAL_PWREx_EnableUltraLowPower();
HAL_PWR_DisablePVD();
SysTick->CTRL=0;
HAL_PWR_EnterSTOPMode(PWR_LOWPOWERREGULATOR_ON,PWR_STOPENTRY_WFE);

while(1);

 

Thanks!
