NRF5340 Enabling dual TrustZone?

[sacca]

Hi, since the Nrf5340 has two identical Cortex-M33 cores, I was wondering whether it would be possible to enable the trustzone for both cores, and if yes, how.

Thanks.

Hi,

The Arm TrustZone for Armv8-M Security Extensions are optional on the Cortex M33 and they are not implement on the Network core MCU (Ref. https://docs.nordicsemi.com/bundle/ps_nrf5340/page/chapters/cpu_network/doc/cpu.html#ariaid-title4).

Best regards,

Vidar

The net core does not have trust zone support AFAIK.
