Embedded Linux Engineering

Developing a Linux-based embedded product is complex. Hardware bring-up, firmware and kernel configuration, driver development, and system updates all require deep expertise across hardware, software, and toolchains. Small mistakes can trigger delays, unexpected bugs, and exacerbate long-term maintenance burdens.

RISCstar helps embedded product teams move fast, avoid common pitfalls, and deliver robust, secure Linux platforms on Arm and RISC-V. Whether you’re building a custom board, updating an existing platform, or integrating new silicon, our engineers ensure your Linux BSP is stable, secure, and built for the future.

The Challenge: Accelerate Bring-Up. Reduce Risk. Ship 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Vendor BSPs that are outdated, unstable, or poorly maintained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 response to CVE’s, updates in the field

These issues can stall production schedules and increase long-term development costs. RISCstar provides the expertise required to overcome these issues, enabling you to accelerate your embedded board bring-up, reduce your development risk and ship your product on time and within budget.

RISCstar Approach to Embedded Linux

RISCstar has a wealth of experience in embedded Linux development and we can often be of help in the following areas:

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 when working =with OpenSBI, TrustedFirmware A, U-Boot and EDK2/UEFI.

We have a wealth of experience supporting SoC’s and peripherals found on embedded boards. We work with mainline Linux, LTS Linux versions and vendor kernels.

We ensure your BSP is cleanly integrated and reproducible no matter what Linux distribution you use. We have a wealth of experience with Buildroot, Yocto/OpenEmbedded as well as Debian or RPM package based systems.

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

RISCstar works with you to provide secure OTA updates for your product with rollback safe deployment. We can work with your board manufacturer on manufacturing provisioning workflows.

RISCstar is an expert at long term maintenance, ensuring reliability of updates using regression testing and CI integration. We can help reduce technical debt by upstreaming and ensure security by addressing CVE’s.

Our engineers’ vast experience with embedded Linux, has allowed us to provide solutions for many SoC vendors and OEM’s in a wide variety of areas:
