Worked on stabilizing LVGL redraw operations for the qemu_riscv64 target within the zephyrproject-rtos/zephyr repository, focusing on embedded systems reliability. Addressed a stack overflow issue by increasing the main stack size and introducing a qemu_riscv64-specific LVGL sample configuration with 32-bit color depth, aligning with target constraints. These changes improved GUI reliability and test stability, particularly for demonstrations and continuous integration workflows. All modifications were implemented in C, leveraging configuration management skills to ensure traceability and ease of review. The work centered on bug resolution rather than feature development, reflecting a targeted approach to enhancing system robustness and maintainability.
