Safety Review
Boot and secure-storage sequencing review
Tightens early boot order, key material handling, and rollback paths for field updates.
Indicative fee: 3 600 000 Ft · informational only
Scope narrative
Boot paths are easy to overfit to the happy case. We walk your ROM loaders, secure-storage policies, and update stubs, highlighting race windows and power-loss corners. Output is engineer-readable, not slide-deck fluff.
Included focus areas
- Boot timeline diagram with measured segments
- Secure key integration review without vendor lock-in pitches
- Rollback matrix for A/B and single-slot schemes
- Flash wear notes where logging verbosity collides with endurance
- UART/USB recovery path sanity check
- Checklist for manufacturing provisioning scripts
Outcomes you can archive
- Fewer bricked units during aggressive field trials
- Clearer responsibilities between BSP and product firmware
- Traceable answers for penetration testers
FAQ
Do you perform penetration testing?
We prepare firmware for tester questions and close obvious gaps. Full pen-tests are a separate engagement.
Which vendors are supported?
We stay vendor-neutral; specifics live under your NDA.
What if keys live in a secure element?
We review the contract between MCU and element, not the silicon internals.
Experience notes
They mapped rollback corners we had hand-waved. Manufacturing stopped arguing about provisioning scripts.
