Vybrid RTC reset after power off

Hi Vybrid's users.

 

I'm having trouble with the SNVS RTC on Phycore Vybrid board using linux. We have the last revision of Vybrid : "2N02G" (with the VBAT issue solved) and it seems that time is lost when we powered off the board, while we have a battery (Vbat = 3.1V).

We used the default SNVS_RTC driver and looking the source file,  it's said that snvs-rtc is used in non secure mode, is that why the time is not stored? it's a normal feature?
