Embedded Linux Engineering

Move fast, avoid pitfalls, and deliver robust, secure Linux platforms on Arm and RISC-V. RISCstar engineers ensure your BSP is stable, secure, and built for the future — from first boot to long-term maintenance.

Accelerate Bring-Up. Reduce Risk. Deploy Faster.

Software development for embedded Linux devices is difficult and exacting work. Development teams face challenges such as:

Vendor BSPs that are outdated, unstable, or poorly maintained
Missing or incompatible drivers in firmware, bootloaders, and the Linux kernel
Complex interactions between power, clocks, PMICs, and peripheral subsystems
Security requirements — secure boot, measured boot, OP-TEE, OS hardening
Distribution and build system fragmentation (Yocto, Buildroot, Debian, Ubuntu)
Long-term maintenance — upstream patch management, timely CVE response, field updates

These issues will stall deployment schedules and increase long-term development costs. RISCstar provides the expertise required to overcome them, enabling you to accelerate board bring-up, reduce development risk, and deploy on time and within budget.

The RISCstar Approach to Embedded Linux

RISCstar has a wealth of experience in embedded Linux development and can help with:

We are experts in debugging boot scenarios and low-level device bring-up and verification — UART, DDR, clock, PMIC, and other peripherals.

We ensure a reliable boot flow and secure foundation for embedded devices. We excel working with OpenSBI, Trusted Firmware-A, U-Boot, and EDK2/UEFI.

We have a wealth of experience supporting SoCs and peripherals found on embedded boards, across mainline Linux, LTS versions, and vendor kernels.

We ensure your BSP is cleanly integrated and reproducible across Buildroot, Yocto/OpenEmbedded, Debian, and RPM-based systems.

RISCstar can help with secure and measured boot, OP-TEE and trusted applications, and securing your user space.

We work with you to provide secure OTA updates with rollback-safe deployment and support manufacturing provisioning workflows with your board manufacturer.

We ensure reliability of updates using regression testing and CI integration, reduce technical debt through upstreaming, and keep your product secure by addressing CVEs.

Why RISCstar? Proven Experience Across Platforms

Embedded Linux engineering spans an unusually broad stack, and few teams have deep expertise across all of it. RISCstar does. Our experience includes:

Accelerating board bring-up for a major SoC vendor by resolving critical boot and peripheral initialization issues across firmware and kernel layers
Delivering a production-ready secure boot and OP-TEE implementation for a medical device platform with strict regulatory requirements
Reducing long-term maintenance costs for an industrial IoT OEM by upstreaming key drivers and eliminating a divergent vendor kernel fork
Integrating a full Yocto-based BSP for a networking platform, enabling clean distribution support and reproducible builds across multiple hardware variants

RISCstar is the partner you want when your embedded Linux platform needs to be right — stable, secure, and built to last.
