RTC Time changing with SD card

Post by Zacks » Wed Sep 08, 2021 2:59 pm

I am interfacing an RTC with OpenMV Cam, everything is working well with the time always being accurate. However, when I inserts SD card and set the time, it will remain correct but when I disconnect the board and reconnect, the time will change. I did not experience this when I was using the board without the SD. Seems there is a way the SD saves time which is different. I will appreciate any idea on how to resolve this.
