Embedded Systems Development
Processor, platform, and software engineered as one system — from bare-metal control loops to embedded Linux.
What is embedded systems development?
Embedded systems development is the engineering of the computer inside a product: selecting the processor, designing the supporting hardware, and writing the software that runs on it. We build embedded platforms from bare-metal microcontrollers to embedded Linux, developed alongside the boards they run on so hardware and software are never strangers.
Hardware and software, one conversation
Embedded work goes wrong when the software team and the hardware team are different companies. The firmware engineer discovers a missing pull-up after the boards are fabbed. The hardware engineer picks a part whose software support turns out to be abandoned. Here, the person writing the driver can walk over to the person routing the board.
That proximity shows up in the product. Pin assignments get chosen for software sanity, test points land where debugging needs them, and the board that arrives is one the software team already knows how to bring up.
Written for the engineer who inherits it
An embedded product ships once and then lives for years, which means someone has to work on the code long after the launch team moves on. We write embedded software for that future: version-controlled from the first commit, built by CI rather than one engineer's laptop, documented at the architecture level, and covered by tests that let the next person change things without fear.
It also means we are comfortable inheriting other teams' projects. An audit tells you what you have. Stabilization comes before new features. Rescues are some of the most valuable work we do.
Bare-metal vs RTOS vs embedded Linux: which platform fits?
The software platform is the biggest architectural decision in an embedded product. Bare-metal keeps everything under direct control on small microcontrollers, an RTOS adds scheduling discipline as complexity grows, and embedded Linux brings a full operating system where the product needs one. Each moves the cost, power, and capability dials differently.
| Bare-metal | RTOS (FreeRTOS, Zephyr) | Embedded Linux | |
|---|---|---|---|
| Best for | Simple, cost- and power-critical devices with one bounded job | Products juggling several real-time tasks at once | Products needing rich networking, displays, filesystems, or heavy computation |
| Typical hardware | 8- to 32-bit MCU with internal flash and RAM | 32-bit MCU, often with wireless on chip | Application processor (MPU) with external RAM and storage |
| Determinism | Total — you wrote every instruction | Hard real-time by design | Soft real-time; hard deadlines need care or a co-processor |
| Startup & power | Instant-on, lowest sleep currents | Milliseconds to start, excellent low-power modes | Seconds to boot; low power is possible but takes engineering |
| Development cost | Low at small scope, grows badly with complexity | Moderate; the structure pays for itself as features stack up | Highest platform cost, fastest application development once running |
Where we work across the stack
How an embedded platform comes together
- 01
Platform Definition
Requirements set the processor and the software platform: bare-metal, RTOS, or embedded Linux. The rest of the project inherits this decision, so it gets made against measured needs.
- 02
Board Bring-Up
Support code comes first — clocks, memory, power states, and a driver for every peripheral, proven with a debugger before application work begins.
- 03
Application Development
Product behavior is built on the stable base: task architecture, state machines, and communication stacks, with code review and CI builds from the first commit.
- 04
Integration & Debug
Software meets real hardware under real conditions. Instrumented builds and logic analyzers chase the issues that only exist at the boundary between the two.
- 05
Verification & Release
Regression suites and hardware-in-the-loop testing gate the release. You receive source, documentation, and images ready for manufacturing programming.

Embedded Systems Development FAQs
An MCU is usually right when the product does a bounded set of jobs and cares about cost, power, and instant startup. An MPU is the right call when you need Linux, rich networking, a display stack, or heavy computation. The choice ripples into board complexity and software platform, so we make it early and against measured requirements.
Yes. We build embedded Linux platforms with Yocto or Buildroot on ARM application processors, including board support, driver work, and boot-time optimization.
Yes, and it is common. We audit the existing code and hardware, document what is there, then stabilize before extending. You get a clear read on what is salvageable — sometimes that is most of it, sometimes it is not.
At several levels. Unit tests run off-target in continuous integration, integration tests exercise drivers on the real board, and hardware-in-the-loop rigs run regression suites against production-intent hardware. For long-life products we also soak-test for the failure modes that only appear after weeks of uptime.
