Hi,

With WICED_ENABLE_MCU_RTC, I would expect after setting RTC time and reboot

then I can still get correct rtc time.

However, I found platform_rtc_init will always setting the rtc time to default_rtc_time during boot.

As a result, everytime reboot the device, the rtc time is wrong.

Note, all support platforms has such behavior - always setting the rtc time to default_rtc_time during boot.

Can someone explain this?

It is true that after reboot, platform_rtc_set_time() will write default RTC time in platform_rtc_init(). Check if you can periodically update the DCT with RTC time and after reset, read the last RTC update saved in DCT.

[AxLi_1746341]

In my use case, the NTP sync may fail.

So I expect I can read correct RTC value after reboot even if NTP sync failure.

You cannot expect people to update RTC value via DCT because I cannot always

get correct date-time to update RTC.

(And if I can always get correct date-time, I even don't need RTC at all.)

I think current implementation is SDK bug.

I re-think your reply and I think it's *wrong*.

No matter how frequently you periodically save the RTC time in DCT, after reboot, the saved-time is incorrect anyway. The time past away.

I agree with your comment... saving time periodically in the DCT is not a good idea.

It's not about agree or not. It just won't work, it's clearly a bug.

And the point is I have waited too long (almost 10 months since I reported it) and still not sure when will the fix available.

Ill see if I can figure out what the state of the JIRA is.

Any update? Can I expect this issue to be fixed in next release?

The same issue was reported here:

Hi cypress team,

Can I expect RTC to be working in next release?

Any update? (This was reported 6 months ago).

[GauravS_31]

I am following up with the engineers (again) for an update. A ticket had been raised on this issue in December. So no comments right now.

It has been quite long time since I reported this issue.

Will upcoming release fix the RTC issue?

wiced-6.6 does not include the fix.

It has been quite long time since this issue was reported, can you update the status?

Still no update?

Reviving this post to see if there has been any updates. I am encountering the same issue with RTCC and wish to not only preserve the time while in hibernate but increment time too.

As of now, when I wake from hibernate, the RTCC registers is reset. NTP is not an option during this mode and i need to timestamp events for a log.

I don't get any update.
