Embedded Linux Development

When a product needs rich connectivity, existing driver ecosystems, and enough compute for on-device inference or complex workflows, embedded Linux is the right choice. We build custom BSPs on Yocto and Buildroot, integrate proven SoMs, and take products through secure boot and update paths.

What it is

What embedded Linux is and when it fits.

Embedded Linux is the kernel and userspace running on Cortex-A-class SoCs (NXP i.MX, TI Sitara, Rockchip, Allwinner, NVIDIA Jetson, and increasingly RISC-V). Compared to MCU-class firmware, it brings the whole Linux ecosystem: standard networking stacks, container runtimes, mature driver support for peripherals, and rich middleware.

We reach for embedded Linux when the compute headroom matters (graphics, inference, complex application logic), when time-to-market benefits from existing driver ecosystems, or when the product needs a familiar userspace for the deployment team. We stay on MCU when the power budget or determinism argues against it.

Where we use it

Embedded Linux Development in shipped programs.

  • Autonomous mower compute stack - Jetson-class embedded Linux running ROS 2 and vision inference
  • Field service management edge devices - Linux terminals with offline-first application logic
  • Manufacturing execution edge computers - Linux industrial PCs bridging PLCs to cloud

Patterns and gotchas

What embedded Linux gives you free - and what still bites.

Start on a SoM, not a custom SoC design. System-on-modules (Toradex, Compulab, Variscite, Seeed) let you validate the software stack on a proven CPU/memory/PMIC combination while your carrier board takes an iteration to catch up. First-project custom SoC layouts are a category of pain we generally recommend against.

Yocto is a job; pick the layers early. Yocto is powerful and steep. We normally start from the vendor BSP layer, add meta-openembedded, and take on custom recipes only where necessary. Buildroot is a legitimate simpler alternative for smaller feature sets - the choice is per-project, not a favourite.

Secure boot means the whole chain, not just the bootloader. Every production Linux product we ship has a secure boot chain (bootloader signature, kernel signature, initramfs signature) and signed A/B partition updates. Retrofitting this after launch is expensive; designing it in adds a week.
