Dharun Krithik K developed and integrated hardware support features across Zephyr-based repositories, focusing on Infineon PSoC4 platforms. He delivered DMA, SPI, UART, and watchdog functionality in nrfconnect/sdk-zephyr and nxp-upstream/zephyr, using C, DTS, and YAML to implement device drivers, device tree bindings, and board overlays. His work included refactoring device trees for maintainability, aligning clock and divider configurations with hardware specifications, and expanding peripheral support for boards like CY8CPROTO-041TP. By enabling robust testing frameworks and cross-repository collaboration, Dharun improved hardware validation, reduced integration risk, and established a foundation for reliable, scalable embedded systems development within Zephyr projects.
For 2026-03, key development focused on expanding hardware capabilities and improving testability in the nxp-upstream/zephyr repository. Major bugs fixed: none reported in this period; effort was concentrated on feature delivery and validation improvements. Overall impact includes broader device support, enhanced test coverage, and stronger validation workflows, contributing to faster time-to-value for new boards and peripherals. Technologies demonstrated include DMA integration, peripheral expansion (SPI, I2C, ADC, counter, watchdog, PWM, flash), SPI loopback testing, and Zephyr board configuration via YAML.

Month: 2025-12. Focus: deliver PSoC DMA platform-wide support and testing in nxp-upstream/zephyr. Key work delivered includes unified DMA support across PSoC platforms: Infineon DMAC driver for PSoC4 Series, DMA controller support for PSoC 4100TP, and board-level DMA testing overlays for CY8CPROTO-041TP. This work is backed by three commits with explicit messages. Impact: enables cross-platform DMA functionality, improves test coverage, reduces integration risk for DMA features, and accelerates time-to-market for PSoC-based platforms. Technologies/skills demonstrated include device-tree integration (infineon,dmac.yaml), board overlays, and driver development for DMAC. Business value: higher performance DMA paths across PSoC devices, streamlined validation, and stronger platform consistency.
