I am working on a project with iMXRT1064.
I am using a SuperCapacitor as a replacement for a coin cell battery.
As per indications on the development kit schematic, I connected supercap to VDD_SVNS_IN.
However, the MCU does not start working until the capacitor has been discharged.
So after use, I have to wait 15 to 20 minutes to get the board running again.
Looking at the datasheet, i found that VDD_SVNS_IN pin is multi-featured. RTC is one of the feature.
Could it be that this pin is by default set to GPIO which could be a high drain source?
This could explain why the board does not power up till capacitor has been discharged?
If yes, in order to use a coin cell or supercap, do we need to configure this pin to RTC?
