Building reliable connected devices demands a firmware foundation that is stable, scalable, and purpose-built for the target hardware. Our embedded linux development services at Sunstream cover the complete software stack — from bootloader and kernel configuration through driver development, board support packages, and application integration. We work across ARM, RISC-V, and x86 embedded platforms, tailoring every layer of the software to the specific hardware design. Our structured development process ensures security hardening, traceability, and over-the-air update capability are built in from the very beginning of the project.
