STM32F4 RTC problem
Posted on May 02, 2018 at 14:51
Hello,
I have a problem. I use a STM32F427 with Keil RTX.
If I start my Programm without a backup battery my Programm runs into a rtos error (stack Overflow) if I want to set the date/time, but at this time the os isn't running.
I use an external 32768 Hz oscillator as LSE clock.
Can anyone give me a hint what I can do to solve this problem?
If I have a battery connected the Programm works fine at the second start, if there is a date/time in the system.
Best regards
Stephan
