Worked on the espressif/developer-portal repository to enhance the accuracy and clarity of PSRAM configuration documentation related to Zephyr RTOS. Focused on removing the unused ESP_HEAP_SEARCH_ALL_REGIONS parameter from the Zephyr PSRAM usage documentation, aligning the content with actual Zephyr capabilities and reducing potential confusion for developers. Utilized Markdown for documentation updates and applied strong documentation skills to improve maintainability and onboarding for new contributors. The work addressed a specific documentation bug, resulting in clearer configuration options and lowering the risk of misconfiguration. This targeted update contributed to more reliable support and streamlined developer experience within the project.
