ARM® Cortex®-M4F - Trustzone?

[allenbjr]

Can anyone confirm; CXD5602PWBMAIN1, does not have TrustZone?

If it does not, is there a roadmap or plan to offer M4+ that has TrustZone instructions?

Hi @allenbjr

This is the answer I got for you: "Spresense doesn't support TrustZone because its chip (Cortex-M4F) is based on ARMv7-M architecture.
TrustZone is the feature of ARMv8-M architecture."
