PROFILE

Mattijs Korpershoek

Worked on the flipperdevices/u-boot and linux-riscv/linux repositories, delivering features and fixes across embedded systems, bootloader development, and kernel-level device drivers. Implemented Android boot image parameter appending in C, enhancing boot configurability for Android v4 devices. Improved repository hygiene and governance by updating contributor metadata and MAINTAINERS files, and streamlined build processes using Shell scripting and CI/CD practices. Addressed runtime power management bugs in the Cadence QuadSPI driver, ensuring robust DMA error handling and stable driver probing. Demonstrated strong documentation management and project coordination, with a focus on maintainable, well-documented code and cross-environment compatibility throughout the development cycle.

January 2026 monthly summary for flipperdevices/u-boot: Implemented Android Boot Image Parameter Appending for Android boot image v4. The change adds add_bootconfig_parameters() to append boot configuration entries and was imported/adapted from AOSP with coding-style adjustments to align with U-Boot conventions. This work improves boot configurability and reliability across Android variants and lays groundwork for future boot parameter management. No major bugs fixed were recorded for this repo in Jan 2026. Skills demonstrated include U-Boot internals, Android boot process, AOSP patch adoption, coding-style refactor, and cross-team collaboration.

October 2025 monthly summary for linux-riscv/linux: Delivered a targeted bug fix in the Cadence QuadSPI driver to improve runtime power management and driver probing robustness, with a focus on correct PM state handling during deferred DMA scenarios. The change prevents pm_runtime_disable being invoked without a prior pm_runtime_enable and adds an explicit DMA failure path to preserve stable runtime power states.
