Hi all!

I have a problem with STM32 BOOT (I used a STM32F207). If the microcontroller restarts (after power-off), the firmware is blocked during the CLK initialization (and RTC initialization).
I changed capacitor of the RTC (20pF instead of 22pF), and the initialization has been right. But i don't understand why. If you any idea or suggestion ?

Best Regards
