Deepika developed foundational platform and driver support for Infineon PSoC4 within the nrfconnect/sdk-zephyr repository, focusing on robust device tree integration, CMake-based build infrastructure, and Kconfig-driven configuration management. She implemented core drivers, including clock control and UART, and expanded hardware support through multi-variant device tree overlays. Her work included a TCPWM-based counter driver with alarm handling and sample integration, enabling precise time-based events and improved interrupt management. In the nxp-upstream/zephyr repository, Deepika enhanced the GPIO testing framework by introducing board-specific device tree overlays, streamlining validation across hardware variants. She primarily utilized C, DTS, and YAML throughout these projects.
