      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."
