I have a new project and the SOC is iMX7s.
I need to implement tamper detection function.
According to the "i.MX 7Solo Applications Processor Reference Manual" in section "188.8.131.52 Tamper Detection", it descriptors the tamper detection function need an always-ON power supply (coincell battery) should be present in the system.
But my project has size limitation and can't support an always-ON power supply (coincell battery).
My question is if there isn't exist an always-ON power supply, how to implement tamper detection function in my project?
