Hope attachment might help

------------------

//do something

rtc_unlock_seq();

printf("RTC: %x\n\r",MCF_RB_RTC_CFG_DATA);

MCF_RB_RTC_CFG_DATA = 0x00000008;

printf("RTC: %x\n\r",MCF_RB_RTC_CFG_DATA);

RTC_GetTime();

------------------

Good luck

Hi Paolo,

Thanks for the information. It was helpfull, now my RTC is clocking.

One question about RTC:

What is the meaning of OSCBYP=0 On-chip 32-kHz oscillator not bypassed ?

Does it mean that the 32Khz is taken from the internally clock system and not from the external 32KHz crystal at RTC_EXTAL ?

Best regards

Pierre Schneider

Nice to hear things are working at your side Pierre. OSCBYP=0 means ext 32.768KHz is used as the RTC reference. If this post helps you, don't forget to mark it as the solution :-)
