Scope
This briefing maps your cold boot chain, isolates blocking I/O, and proposes a staged bring-up plan that keeps deterministic checkpoints for factory and field.
Included analyses
- Vector table and early clock verification checklist
- Flash XIP vs copy-to-RAM trade study for your geometry
- Driver staging matrix with parallelizable steps
- Watchdog and brown-out interaction review
- Signed image path latency audit
- Deferred service table for non-critical peripherals
Outcomes you can publish internally
- A ranked backlog of boot contributors with measured deltas
- A two-sprint sequencing plan aligned to your release train
- Instrumentation hooks your CI can keep running
Lead advisor
Haneul Park
Principal firmware advisor focused on deterministic start-up for connected devices.
FAQ
Do you rewrite our bootloader?
We recommend changes; your team retains implementation authority. We do not ship proprietary bootloaders.
What if our toolchain is vendor-locked?
We document constraints honestly. Some vendor blobs cannot be optimized without cooperation from the silicon partner.
Is on-site work included?
Travel is quoted separately for Seoul metro; remote-first is default to keep calendars predictable.
Experience notes
“The Boot Ledger brief named our SPI flash contention issue before we burned another EVT cycle.”
