Worked on stability improvements for the zephyrproject-rtos/trusted-firmware-a repository, focusing on resolving a critical boot-time issue affecting Neoverse platforms. Addressed an assertion failure in SMMU routines by moving timer initialization earlier in the boot process, ensuring that dependencies were properly ordered and preventing startup crashes. This fix involved careful analysis of the platform’s initialization sequence and required changes to embedded C firmware. Leveraged expertise in embedded systems, firmware development, and platform setup to enhance reliability for Neoverse deployments. The work resulted in a traceable, concise code change that improved overall platform stability without introducing new features during the period.
