As an embedded developer, I want vemu to model STM32 OTFDEC on-the-fly flash decryption, so that I can build and test firmware that needs Running encrypted XIP images on STM32L5/U5/H7B as the boot ROM expects long before the hardware is in hand.

Why it matters

Running encrypted XIP images on STM32L5/U5/H7B as the boot ROM expects

Summary

On-the-fly AES decryption of execute-in-place code/data fetched over OCTOSPI

Scope of work

Not present today. Deliver a behavioral model of STM32 OTFDEC on-the-fly flash decryption. What it is: On-the-fly AES decryption of execute-in-place code/data fetched over OCTOSPI. Why it matters: Running encrypted XIP images on STM32L5/U5/H7B as the boot ROM expects.

Current state

Status: stub. Notes / evidence: STM32-specific IP modeled in crates/vemu-soc-st; no generic story covers it.
