Worked on the zephyrproject-rtos/poky repository to deliver a compatibility update for Yocto Uninative, enabling support for glibc 2.41. The update involved upgrading yocto-uninative to version 4.7 and extending the maximum supported glibc version, with refreshed checksums for aarch64, i686, and x86_64 architectures. This work, implemented in C and focused on build systems and embedded systems, addressed reproducibility and reliability issues in continuous integration pipelines. By mitigating rebuild breaks with newer toolchains, the update strengthened downstream compatibility and ensured that builds remained consistent across multiple architectures, supporting ongoing development and deployment in embedded environments.
