PROFILE
Lukasz Majewski
Lukma developed and optimized embedded Ethernet and board bringup features across the kholia/zephyr and flipperdevices/u-boot repositories. In kholia/zephyr, Lukma reworked the LAN865x driver to use a RAM-allocated configuration table, reducing flash usage and improving update efficiency, while also aligning PLCA control register handling with AN1760 guidelines for better reliability. For flipperdevices/u-boot, Lukma enabled BTT i.MX287 device support and resolved critical boot-time issues on vf610 boards, including QSPI memory recognition and pinctrl misconfigurations. These contributions, implemented in C and Device Tree, demonstrated strong skills in driver development, hardware configuration, and embedded systems engineering.
