Build, recover and manufacture
Production Firmware Pro
Turn prototype code into testable, versioned and recoverable firmware with traceable device identity and manufacturing evidence.
Architecture
Non-Blocking Firmware Architecture
Replace long delays and blocking I/O with deadlines, events, bounded work and observable task health.
Open production lab →ArchitectureState-Machine Design and Validation
Model operating modes, events, transitions, guards and timeouts explicitly.
Open production lab →RTOSFreeRTOS Task and Queue Design
Partition work into bounded tasks with queues, ownership, priorities and measurable stack margins.
Open production lab →ReliabilityWatchdog Configuration and Recovery
Configure watchdog coverage so a stalled critical path resets safely and records a useful cause.
Open production lab →PowerDeep Sleep and Battery Optimisation
Measure active/sleep current, duty cycle and wake reliability to estimate realistic battery life.
Open production lab →ReleaseSemantic Firmware Versioning
Create traceable semantic versions, build identifiers and hardware compatibility rules.
Open production lab →OTAOTA Update Pipeline
Download, authenticate, stage and confirm firmware without replacing the known-good image prematurely.
Open production lab →OTAAutomatic Rollback and Recovery
Return to confirmed firmware when the candidate crashes, fails health checks or misses confirmation.
Open production lab →SecuritySecure Boot Planning
Establish a vendor-supported chain of trust from immutable boot code to signed application images.
Open production lab →SecurityFlash Encryption Planning
Protect code and sensitive data at rest using the MCU vendor’s supported encryption lifecycle.
Open production lab →SecurityEncrypted Configuration Storage
Store credentials and configuration with authenticated encryption, schema versioning and safe update semantics.
Open production lab →LifecycleFactory Reset and Recovery
Return user configuration to a defined state without accidentally destroying required manufacturing identity.
Open production lab →ManufacturingDevice Provisioning Workflow
Create a unique, auditable device identity and inject only the minimum required configuration.
Open production lab →IdentitySerial Numbers and Hardware Revisions
Maintain stable device identity and explicit compatibility across board changes.
Open production lab →ManufacturingCalibration Record Management
Store traceable calibration coefficients with units, method, date, equipment and integrity protection.
Open production lab →ManufacturingManufacturing Self-Test
Run deterministic fixture tests and produce a per-device pass/fail record before packing.
Open production lab →DiagnosticsDiagnostic Export and Service Bundle
Export useful health evidence while removing credentials, personal data and raw cryptographic material.
Open production lab →ReleaseProduction-Readiness Release Gate
Require evidence for architecture, security, recovery, manufacturing and support before approving release.

Firmware production workbench
A/B update exercise
OTA and automatic rollback simulator
Advance one validated stage at a time. A failed boot test returns the device to the previous slot.
- Running confirmed firmware from Slot A.
Release gate
Production-readiness checklist
A downloadable release decision is generated only after every mandatory control is confirmed.
