Worked on improving image cache reliability for the lvgl/lvgl repository, specifically targeting Nuttx-based embedded systems. Addressed a cache management issue by implementing invalidate_cache and flush_cache callbacks within the image_cache_draw_buf_handlers, ensuring that stale image data would no longer persist during rendering. This technical approach involved careful sequencing of cache invalidation and flushing, aligning with LVGL’s broader caching policies. The work was carried out using C and leveraged expertise in cache management, driver development, and embedded systems. By focusing on this targeted bug fix, the developer enhanced the stability and reliability of image rendering for Nuttx deployments without introducing new features.
