Change Note 2026-02-13

Secure/Non-secure program separation, part 4 (RP2350, update).

Test Program

A pure TrustZone implementation for the separation of Secure and Non-secure programs for MCUs with ARM TrustZone technology: [Secure/Non-secure Part 4]({{< relref "/docs/examples/v3/secure3" >}}).

Implemented on the RP2350 – not using bootrom's secure_call, but real NSC veneers, just as for the STM32U585.
