Periodic RTC wakeup without LSE

Hi,

I'm trying to make STM32F3 device wake up from sleep using LSI. According to datasheet it should not require LSE for such operation. I do get no wakeup interrupt if I don't connect 32khz external crystall or disable LSE by software. Maybe it could be a problem with my code, but I see the same behaviour on IAR examples too ("StdPeriph_Lib\Project\StdPeriph_Examples\RTC\RTC_LSI")

I've tried that on STM32L-discovery too. Results are the same. Does anyone tried to run STM32 RTC wakeup functions without external crystal?
