PROFILE

Simon Holesch

Worked on expanding hardware support in the flipperdevices/u-boot repository by implementing DRAM size detection and enabling 256 MiB DRAM support for the imx6ulz_smm_m2 board. Developed and integrated DDR timing configurations for both 128 MiB and 256 MiB variants, updating the SPL boot sequence to automatically detect and configure DRAM size at startup. Modified Makefile build paths to accommodate new RAM configurations, ensuring compatibility across hardware variants. Focused on low-level hardware initialization and Board Support Package (BSP) development using embedded C, with an emphasis on robust DRAM configuration. No major bugs were addressed during this development period.
