Battery RAM not saving data

Walter Gazdzik

Having problem with Battery RAM area 0xE0084000 - 0xE00847FF. Have 32 data stored there, but it is lost when power is removed.
Vbat is connected and battery voltage is good. RTC retains date & time data just fine.

Made sure the Linker Scatter file does not have zero-init applied.

Not sure what I'm missing?

Any help would be appreciated.

Thanks,

Walt

    Seems that when the Battery RAM area is allocated with linker, the area is set for zero-init (ZI). When I removed all reference for allocation (in scatter file), it now works, but I get a warning on the linker that no algorithm found for the Battery RAM area. ..... go figure?

    To all, the help is appreciated!
