PROFILE

Simon Holesch

Simon Holesch developed expanded DRAM support for the imx6ulz_smm_m2 board in the flipperdevices/u-boot repository, enabling compatibility with both 128 MiB and 256 MiB memory variants. He implemented DRAM size detection at boot by updating the SPL initialization sequence and configured DDR timings for each supported size. Simon also modified the Makefile to accommodate new RAM configurations, ensuring robust build processes for different hardware variants. His work focused on low-level hardware initialization and Board Support Package (BSP) development using embedded C, addressing the need for broader device support and improved boot reliability in embedded systems without introducing new bugs.

May 2025: Focused on expanding hardware support in U-Boot for imx6ulz_smm_m2. Key feature delivered: DRAM size detection and 256 MiB DRAM support, including DDR timing configurations for 128 MiB and 256 MiB, SPL initialization to detect DRAM size at boot, and Makefile updates to accommodate new RAM configurations. No major bugs fixed this month. Impact: enables 256 MiB memory variant compatibility, broadens device support, and improves boot robustness across hardware variants. Technologies/skills demonstrated: embedded C, U-Boot board-level development, DDR timing configuration, SPL boot sequence, Makefile integration, hardware initialization."
