Worked on low-level memory and hardware initialization for the flipperdevices/u-boot repository, focusing on DRAM controller support and device driver development for Sunxi platforms. Delivered features such as LPDDR4 and LPDDR3 DRAM initialization, robust DRAM size detection, and cross-platform code refactoring to improve maintainability and reliability across SoC variants. Addressed hardware compatibility by aligning parameter handling and fixing parsing bugs, while also enhancing eMMC and memory bring-up stability. Contributed to xbmc/xbmc by improving HDR metadata handling at startup. Utilized C, CMake, and Git, applying embedded systems expertise and continuous integration practices to ensure reliable hardware interaction and maintainable code.
Monthly performance summary for 2026-04: Focused on stabilizing memory initialization path for Allwinner LPDDR3 in U-Boot, delivering a targeted fix to DRAM TPR6 parsing and aligning behavior with existing A133/A523 code paths, resulting in improved boot reliability and hardware compatibility across Allwinner platforms.

April 2025 monthly summary for flipperdevices/u-boot: Delivered cross-platform DRAM initialization refactor enabling shared code paths with Sunxi H616. Key changes include const-correct function parameters, splitting the DRAM parameter struct into dram_para and dram_config, and extracting common helpers into shared code to reduce duplication and improve maintainability across H6/H616. In parallel, fixed DRAM size detection on Sunxi H6 by reusing the common DRAM infrastructure and integrating new helper functions into the build, improving initialization reliability. These efforts reduce platform fragmentation, streamline future enhancements, and lay groundwork for broader cross-platform reuse. Technologies demonstrated include C refactoring, const-correctness, modular struct design, and build integration for cross-platform code reuse.

In March 2025, delivered critical low-level improvements for Sunxi H616 bring-up in flipperdevices/u-boot, strengthening hardware reliability and operational stability. Implemented a dedicated MMC reset refactor into sunxi_mmc_reset to stabilize eMMC operations on Sunxi platforms, and enhanced DRAM size detection with a more robust algorithm, testing patterns, and address-wrapping checks to prevent mis-detection and ensure BSP alignment.
