fsl_rtc... Why do not save time?

Hi to all.

I'm developing on K20; I use KDS 2.0.0

I use the RTC_LDD component for Real-Time-Clock without using KSDK (for K20 KSDK is not ready yet...).

I set via the time via my Firmware and I turn off my device for two days.... and turn on... It give me the correct date and time!

Now I try to use KSDK 1.1.0 setting K60 uP instead K20; all seems work correctly but fsl_rtc component don't work well...

For the first thing I see that If i do not explicit do this instruction:

 

    uint32_t rtcBaseAddr = g_rtcBaseAddr[FSL_RTCTIMER1];

    RTC_HAL_EnableCounter(rtcBaseAddr, true);

 

the automatic init procedure do not enable it automatically.

 

The second (and very big problem....) is that if I turn off and turn on my device it will lost my time!

 

I suppose that this component do not work right... what I can do for preserve my time during turn off?

 

Many thanks,

Massimiliano
