Hello,
1) I won't use the internal RTC or anti-tampering so, it's necessary to power the SNVS using a battery?
Yes, it's not necessary to power SNVS using a battery. VDD_HIGH_IN and VDD_SNVS_IN can be tied together if the real-time clock function is not needed during the system power-down.
2) Could be possible to authenticate an image that resides on a SD Card?
Yes, this is possible.
Regards,
Victor
