Embedded Linux is a superpower — and a trap. The flexibility of the Linux kernel means you can run on almost any hardware, but getting a stable, minimal, production-ready image that boots in under 3 seconds, fits in 128MB of flash, and survives 10 years of field operation requires deep expertise in the Yocto Project build system, the Linux kernel, and the hardware itself.
Codewave Labs has built Yocto BSPs from scratch for industrial IoT gateways, medical imaging devices, smart EV chargers, digital signage players, and custom NXP i.MX8 and Xilinx Zynq platforms. We write clean, upstreamable meta layers, not one-off hacks.
We also take over troubled BSPs — if your Yocto build is slow, your image is bloated with packages you don't need, your kernel is out of date, or your board has a mysterious 30-second hang during boot, we can fix it.
Full BSP layer creation from bare metal: machine configuration, U-Boot recipe, kernel recipe, device tree, machine features, and DISTRO configuration.
Minimal production images with only required packages, read-only rootfs, overlay filesystems, A/B partition schemes, and secure boot integration.
U-Boot porting, SPL/TPL configuration, custom board files, display init, network boot, USB mass storage, and verified boot chain.
Complete device tree and device tree overlay development for custom hardware: pin mux, clock tree, regulators, display pipelines, and PCIe.
SWUpdate, Mender, RAUC, or custom OTA pipelines. A/B rootfs, delta updates, rollback safety, hardware-enforced update verification.
Systemd analysis with systemd-analyze, initramfs optimisation, kernel config trimming, parallel boot sequencing. We routinely achieve sub-3s boot times.
Review schematics, SoC reference BSP, and existing codebase. Identify clock tree, power domains, and peripheral requirements.
Design clean meta layer structure, machine config, kernel config fragments, and recipe organisation before writing a line of BitBake.
Bring up U-Boot → kernel → rootfs incrementally. Each peripheral validated on hardware before moving on.
Security hardening, read-only rootfs, OTA pipeline, boot time optimisation, and full documentation handoff.
