Bootloader & startup review

Focused pass on the code that runs before your application—where bricking costs are highest.

We trace reset vectors, clock initialization, flash programming routines, signature checks, and rollback guards. Engagements usually span two to four reviewer days.

Deliverables match the flagship review format but emphasize boot paths, upgrade state machines, and watchdog behavior during flash writes.

Book this pass when OTA or dual-bank swap is on your roadmap.
