Hello!

I have a problem with low power mode on stm32f103 and stm32f407. When I try to put them in Stop mode they still consume about 4-5mA which is too much ( it should be about 300uA). Here's the image http://stm32f4-discovery.com/2014/10/library-39-power-consumption-modes-for-stm32f4/ . I put it to Stop mode through:

PWR_EnterSTOPMode(PWR_Regulator_LowPower, PWR_STOPEntry_WFI);

I don't do any RCC on GPIO configuration. Above line is the ony line in my program. 
Also I don't have any external devices connected to STM, any pullup resistors etc.

What am I doing wrong ? 

greetings,
Peter
