PROFILE
Manikandan Muralidharan
Manikandan contributed to the flipperdevices/u-boot repository by developing and refining board support for ARM-based platforms, focusing on the SAM9X60 and SAM9X75 families. He enhanced device tree integration and alignment with Linux Devicetree conventions, improving hardware bring-up and kernel compatibility. Using C, DTS, and Kconfig, he implemented features such as AIC support, pinctrl and GPIO enhancements, and full SAM9X75 Curiosity board initialization. His work included codebase maintenance, restructuring device tree bindings, and streamlining clock subsystem logic. These efforts improved maintainability, reduced integration risk, and accelerated development for embedded systems targeting ARM architectures within U-Boot.

Jun 1, 2025June 2025: Delivered SAM9X75 Curiosity board support (DTS, board init, MMC boot defaults); cleaned up outdated header includes in clock code; strengthened clock subsystem by removing unnecessary parent_name check. Collectively these changes improve hardware bring-up speed, reliability, and maintainability for the SAM9X7/75 family, while reducing documentation and include-path maintenance overhead.
