Firmware development services

SaM Solutions provides firmware development services for custom boards, connected devices, and industrial equipment. We build the software that controls your hardware, connects its components, and supports the functions your product needs.

Bring us a device concept, an early prototype, or firmware that needs attention. Our embedded engineers can develop a new solution, resolve performance issues, or adapt existing code to a different platform.

Our firmware development expertise

Custom firmware

We develop firmware for microcontrollers and systems-on-chip, including bare-metal and real-time operating system implementations. The work covers peripheral control, sensor inputs, communication, and application logic within the device’s memory and processing limits.

Android firmware

Our engineers adapt Android to custom hardware, connecting board-level functionality with the operating system and applications. This includes platform configuration and the drivers needed to make device components accessible.

Linux firmware

We build and customize embedded Linux environments, including kernel configuration, peripheral support, and system integration. The aim is a software foundation suited to the board and its intended workload.

Custom firmware development services we offer

Our custom firmware development services cover architecture, implementation, hardware integration, testing, and optimization. You can hire us for a single task, like a driver or a code audit, or have us take the whole product from first requirements to a finished device.

Firmware consulting and audit
Firmware consulting and audit

We read through your requirements, go through the existing code, and look at what the platform can and can’t handle. After that, we give you our findings and a plan for fixing the current firmware or building a new one.

RTOS-based firmware development
RTOS-based firmware development

For systems that run on a real-time OS, such as FreeRTOS or SafeRTOS, we write the tasks, the peripheral handling, and the application logic. We plan around your timing requirements first. Memory use and inter-task communication follow.

Bare-metal firmware development
Bare-metal firmware development

Some devices run without an operating system. We write code that works directly with the hardware, which suits devices that do one job and have very little memory to spare.

Device driver development
Device driver development

We write drivers for sensors, storage, displays, network controllers, and other peripherals, or adapt the ones you already have. Without them, the rest of the software can’t use the hardware.

Real-time applications for SoCs
Real-time applications for SoCs

We build applications for systems-on-chip and handle how processing, memory, and I/O work together. Your response deadlines and the hardware the chip actually offers decide how we design it.

Communication stack development
Communication stack development

We implement wired and wireless communication between components, devices, and outside systems. The protocol depends on range, data volume, power budget, and where the device will operate.

Legacy firmware migration
Legacy firmware migration

If you’re moving existing firmware to new hardware, we port it, rewrite the parts tied to the old platform, and check that the device still behaves the way it should. We can also prepare the product for future updates while we’re at it.

Firmware testing and validation
Firmware testing and validation

Our QA engineers test by hand and with automation, covering functionality, compatibility, reliability, and security. We first check individual components, then the complete device.

Performance and power optimization
Performance and power optimization

If the device starts slowly, wastes processing time, runs out of memory, or drains the battery too fast, we first measure to find the problem, then change the code. That keeps responsiveness, battery life, and resource use in balance.

Custom firmware solutions for IoT & consumer electronics

Linux kernel development

Kernel customization connects the operating system with your hardware and supports the required device behavior.

Board support packages

We assemble bootloaders, kernels, drivers, and build components into a usable software foundation for custom boards.

Digital signal processing

Our firmware expertise includes DSP solutions for processing signals in embedded devices, considering the product’s performance requirements.

Android Open Source Project development

We adapt Android platform software for dedicated devices, enabling hardware-specific features and application integration.

Network connectivity

We connect products through technologies such as Bluetooth/BLE, Wi-Fi, Ethernet, and cellular communication, with the wider IoT architecture considered alongside device behavior.

Device and application integration

We link firmware with mobile apps, cloud services, and back-end systems so users can monitor devices, change settings, and receive relevant information.

FAQ

How much does a custom firmware project typically cost?

It depends on the project. Updating a driver and building firmware for a new connected product are very different amounts of work. The price depends on the hardware maturity, what the device needs to do, which platforms it must support, what it integrates with, and how much testing it requires. Send us your specifications and any existing code. We’ll go through them and prepare a proposal for your project.
