How to replace battery for SNVS without clean ZMK?

Hi,

I am working on IMX8MP evk，I want to implement tamper protection, When tamper happened, ZMK will be cleaned. In my opinion SNVS works in power-always-on domain, so we need to place a cell battery.

My question is when cell battery is dead，the ZMK will be cleaned? And do I have any way to replace a new battery without cleaning the ZMK?

Thanks.

Hi @brucezhao

As far as I know, there is no way to replace to battery without cleaning the ZMK.

Best regards
