Worked on the zephyrproject-rtos/poky repository to improve documentation accuracy for Bitbake’s hash server configuration. Focused on updating the BB_HASHSERVE_UPSTREAM reference in the user manual, the developer ensured that the documentation reflected the new hash server address, hashserv.yoctoproject.org:8686, replacing the outdated endpoint. This change aimed to reduce build-time confusion for both users and continuous integration systems by aligning documentation with current infrastructure. The work involved careful editing of reStructuredText (rst) files and emphasized documentation skills, resulting in more reliable build processes and easier maintenance for the project’s user base. No new features were added during this period.
