Firmware & embedded software
The software layer that brings hardware into a working system.
Firmware connects the behaviour of electronic hardware with the functions expected from a product. It operates close to the design constraints of the device, while exposing useful interfaces to the rest of the system. Orelink develops firmware and embedded software alongside its hardware engineering capabilities.
Close to the hardware
Embedded software needs a clear model of the hardware it controls. The relationship between processing resources, memory, peripherals and external interfaces informs the structure of the implementation. Hardware and firmware decisions should be understandable to both teams.
The appropriate execution model, toolchain and operating environment depend on the product. Specific platforms and development technologies should be confirmed within the technical scope of an engagement.
Define behaviour explicitly
Operating states, transitions and the handling of unexpected conditions are part of the software’s behaviour. Making these decisions visible helps connect implementation detail to product requirements.
Interfaces between embedded components and higher-level software also need a clear definition. A well-understood boundary allows the surrounding system to interact with the device without depending on hidden implementation assumptions.
Integration across layers
A firmware task may involve hardware bring-up, device control or communication with other system components. The relevant scope depends on how much of the wider product is included in the engagement.
Orelink’s combination of hardware design and software development supports these cross-layer discussions. The aim is consistency between the electronic design, the embedded behaviour and the expectations of the larger system.
Validation and maintainability
Embedded software needs checks that reflect its relationship with physical hardware. Test conditions, observable behaviour and the intended configuration should be recorded so that results remain useful through integration.
Clear interfaces and documentation support subsequent integration and maintenance. Update behaviour, diagnostic functions and other lifecycle requirements are defined within the product scope.
