Building Reliable Systems — Without Losing Control
At Teleconnect, we keep embedded systems simple, cost-driven, and understandable.
That means: BSP-first, minimal deltas, and zero dependence on frameworks we can’t audit or strip. If you want a system you can actually debug in year five, not just demo for a roadmap slide, read on.
What We Actually Do
Start with the BSP: We pick SoCs and vendor BSPs that cut cost and time-to-market, then rip out the bloat. Only the drivers, packages, and services we really need make the cut.
Tailor for Control: CPU and IRQ affinity, bounded work units, hardware acceleration first, minimal software layers. Hot data stays local, no priority inversion, no black-box magic.
Benchmark on Real Hardware: We don’t trust datasheets. We measure latency and jitter end-to-end on your actual board, under your real workload.
Minimal Observability: We add just enough counters, traces, and watchdogs to know what’s happening when things go sideways. No 500 MB monitoring agents. No framework hell.
Security by Design (Not by Checkbox): Attack surface stays small by default. Everything not needed is out. Secure configs, signed updates, and a real support window—not just empty promises.
SBOM and CI: Every release gets a clean, machine-readable SBOM. CI builds are reproducible and auditable. If it isn’t in the SBOM, it isn’t in the field.
How We Handle the EU Cyber Resilience Act (CRA)
The more fuzz and frameworks you have, the harder CRA gets. We do only what’s required—here’s the checklist:
Security Concept: Short, explicit threat model. Secure-by-default settings. Updates and lifecycle policy are documented and enforced.
Vulnerability Handling: Intake, triage, fix, notify. One point of contact. ENISA platform ready by 2026. We don’t just patch; we document what, when, and why.
SBOM: Machine-readable, always fresh, and built right into CI. Only triage CVEs for what’s actually shipped.
CI/CD: Signed artifacts, dependency checks, test evidence for conformity. No bloat, just what’s needed to pass the audit and sleep at night.
Technical Documentation: Risk assessment, SBOM, test logs, update plan, and process docs—present and kept up-to-date, but not a page more than necessary.
The Cost-Driven, BSP-First Truth
BSPs keep us lean, but we read and review every line that ships. If it isn’t understood, it isn’t in production.
Minimalism preserves reliability, security, and long-term maintainability. More frameworks just multiply risk, dependencies, and cost.
We document our deltas, automate what matters, and keep future rebasing cheap and straightforward.
What You Get
A system you can understand, maintain, and audit—in year one or year ten. No hidden magic. No “just trust the framework.”
CRA-readiness baked in: security concept, SBOM, CI, vulnerability process, evidence bundle.
Real-time performance and security—measured on your board, not assumed.
One More Thing: Your Priorities, Not Our Dogma
Our default is minimal, auditable, and under control—because that’s what we’d want to maintain ourselves. But at the end of the day, you’re the customer. If your requirements, ecosystem, or compliance team push us toward a specific stack, framework, or process, we’ll follow your lead and deliver what you need.
We’re not in the business of telling you what’s “right” for your product—we’re here to build the system you actually want. If that means shipping more complexity or integrating the stack your team already knows, we make it work and keep it as robust and maintainable as possible. Our job: deliver what fits your real-world constraints and goals.
If you want embedded systems that ship on time and stay under control, talk to us. We’ll help you keep it simple, secure, and ready for real-world scrutiny—without losing your grip.
