iMx7 tamper

Hi,

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 "3.1.4.2 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?

Thank you.

seems this is not feasible with i.MX7S/D as its tamper functionality requires

always-on power supply.

Best regards
