PROFILE

Jingxing Lai

Worked on hardware enablement and reliability improvements for the Seeed XIAO nRF54L15 board within the renesas/zephyr and nrfconnect/sdk-zephyr repositories. Delivered features to auto-enable the on-board ceramic antenna and VBAT regulator by default, updating the device tree to configure GPIOs for antenna switching and power control. Enhanced board readiness by enabling wireless and sensing peripherals, adding GPIO mappings, and fixing IMU device tree bindings for proper driver integration. Introduced mass-erase recovery for AP-locked devices using OpenOCD and Tcl, improving recoverability. Focused on embedded systems, device tree configuration, and hardware debugging to streamline onboarding and support Matter-ready applications.
