AWS DeepRacer device owners can now install custom operating systems and modern software stacks, extending the hardware's lifespan beyond the limitations of original factory firmware. The company released a new developer bootloader on July 20, 2026, enabling users to bypass previous restrictions that limited devices to outdated Ubuntu 16.04 and 20.04 versions. This tool allows for the deployment of modern Linux distributions, the addition of custom hardware drivers, and the prototyping of vehicle algorithms.

The solution, based on an open-source shim project, provides self-service access through a developer shim that manages certificates and verifies system integrity. When active, the device blinks "DEVELOPER MODE" in Morse code using its onboard lights and displays an on-screen warning via HDMI for 21 seconds during the boot sequence. Developers can manage their own security certificates using standard tools like OpenSSL to maintain cryptographic verification of the boot chain. If a user needs to revert to the factory configuration, the process is fully reversible by following official vehicle update guidelines.

The community-driven adoption is already underway, with the open-source collective at deepracing.io releasing a new custom distribution built on Ubuntu 24.04 and ROS2 Jazzy. This pre-packaged option removes non-essential packages, such as the X Window System graphical interface, to prioritize racing performance while offering an out-of-the-box installation experience. Developers have three primary paths to utilize this new flexibility: installing an existing community distribution, implementing a custom third-party OS by configuring the BOOTX64.EFI file, or building an entirely custom environment from scratch.

This bootloader integration complements the self-managed AWS DeepRacer solution launched on January 26, 2026, granting users end-to-end control over both cloud-based training environments and physical hardware. By placing the shim file in the device's EFI/BOOT directory and storing kernel certificates in the specified EFI/DEVELOPER/CERTS path, developers can run highly customized software stacks. Comprehensive technical documentation, including troubleshooting steps and advanced configuration details, is available in the USAGE.md file provided with the developer shim package.
