Engineering insights from EXPERTiS
From proof of concept to a complete embedded product — what the TGV-101 development cycle taught us about hardware design, firmware architecture, and building things that actually ship.
Communication interface, image integrity, transmission security, and fail-safe recovery — the areas every production bootloader must address beyond any available base.
A bootloader is not a feature — it's a parallel project. Why any existing implementation is a starting point, not a solution, and how to validate it before trusting it.
In 1986, a client asked if we could make an AC voltage regulator speak to the user during alert conditions. A look at the SPO256 speech synthesizer, the Intel MC8748, and the firmware decisions that made it work.
