PROFILE
Naman Jain
Naman Jain developed and maintained embedded device drivers and system features for the Samsung/TizenRT repository, focusing on hardware-software integration for platforms like rtl8730e and bk7239n. He implemented touch and LCD display support, including multi-touch handling, power management, and vendor-specific initialization, using C and Makefile for low-level programming and build system management. His work included modularizing kernel and application boundaries, enhancing test coverage, and improving debugging through targeted logging and fault visibility. By addressing both feature delivery and codebase cleanup, Naman ensured robust hardware compatibility, streamlined configuration, and maintainable embedded systems, demonstrating depth in driver development and system configuration.

Feb 1, 2026February 2026 — Samsung/TizenRT: Focused on modularity improvements. Key feature delivered: Separation of kernel and application headers for bk7239n. Removed app-related header files from bk7239n board to ensure kernel headers do not include application headers, reducing dependencies and enabling cleaner kernel/app boundaries. This work improves maintainability and sets the stage for broader modularization across the project. Commit 42a2777782263b61f29de8475868e2146ee1a190 documents the change (os/board/bk7239n/src/: Remove app related header from bk7239n board file; Kernel files should not include app header files). The same commit touches BEKEN internal debug CLI tooling to remove an extra header as part of the modularity effort.

Sep 1, 2025September 2025 (Samsung/TizenRT): Implemented backlight PWM frequency control for the ST7785 MIPI LCD. Delivered a new feature to set the PWM frequency for the LCD backlight with an initial default of 20 kHz. The frequency is configurable in the device header file but cannot be changed at runtime by applications due to vendor-defined constraints. Commit: 723af19a3b75aa248c375f6a54f6e3cd88ab84d2 (os/: Add PWM frequency set for ST7785 MIPI LCD).
