An embedded Linux platform your product can live on for a decade

The work spans the whole stack. Board support packages for common silicon — NXP i.MX, TI Sitara, Rockchip, and others — get tailored device trees describing your hardware, plus kernel drivers where your peripherals need them. Images are stripped to what the product requires, which shrinks both attack surface and boot time. Updates use an A/B partition scheme through RAUC or Mender: the new image installs to the inactive slot, the bootloader tries it, and a failed boot rolls back automatically — so a bad update in the field is an inconvenience, not a brick. Secure boot and signed images keep untrusted code off the device.

Production success is measured in dullness: fleet update success rates near total, reproducible builds under version control, and a CVE patching cadence that keeps security teams satisfied without destabilizing devices. Factory provisioning — flashing, serialization, per-unit keys — is part of the deliverable, because a platform that cannot be manufactured efficiently is not finished.

Hardware choice shapes everything downstream, so we weigh it early. A system-on-module from an established vendor — with a maintained kernel tree and published longevity commitments — is usually the right foundation for volumes below the point where a fully custom board pays for itself; it moves the hardest layout and memory-interface work onto a supplier and leaves a simpler carrier board to design. Where a custom board is justified, we pick silicon with mainline or well-supported vendor kernels, because a chip that only boots on a frozen fork becomes the ceiling on your product's security and lifespan.

Above the OS, the application layer is kept separate from the platform so each can move at its own pace: application code deploys as its own package or container, talks to the outside world over standard interfaces — MQTT, REST, a local database — and never depends on undocumented quirks of a particular image. Everything is handed over in a repository you own: the build configuration, layer recipes, signing setup, and a written procedure for producing a release from a clean machine. The maintenance arrangement is explicit — who tracks upstream kernel and package advisories, how often patched images ship, and how a release is qualified before it reaches the fleet.
