PROFILE

Zjian Zhang

Zjian Zhang developed and integrated hardware platform support for Realtek Ameba devices within the zephyrproject-rtos/zephyr repository, focusing on board bring-up, device tree configuration, and driver development. Over three months, he enabled platform readiness for AmebaG2 and Amebad by implementing pin control, binary blob handling for multi-CPU execution, and streamlined flashing workflows using C, Python, and CMake. His work included adding initial RTL8721F Evaluation Board support and enhancing West YAML configuration for cross-repository compatibility. By addressing compile warnings and automating build and deployment processes, Zjian improved maintainability and accelerated hardware evaluation, demonstrating depth in embedded systems and firmware development.
