Is it possible to change the status of the "SNVS security state machine" programmatically?

[stefanotatini]

Processor IMXRT1175 (SDK_2.x_MIMXRT1175xxxxx version 2.13.0)

Is it possible to bring back to state machine to the INIT state programmatically (with a software reset)? In other words: is it possible to induce the CPU to reassess the security status of the system programmatically, by invoking "NVIC_SystemReset()" or using some other reset procedure, or is it absolutely necessary to have a physical power cycle?

I refer to the document "Safety Reference Manual i.MX RT1170 processor" par. 6.4.1 Security Monitor (SNVS) security states

Thanks for the support.

Hi @stefanotatini ,

You must trig a POR reset to renew the key as the SRM says.
