PROFILE
Bh Li
Over five months, Bli contributed to the AmbiqMicro/ambiqzephyr repository by developing and refining storage, memory, and data acquisition features for Apollo510 and Apollo3 boards. Bli implemented flash and NVS storage support, expanded board and driver configurations, and introduced DMA-based ADC data acquisition using C and Device Tree overlays. Their work included aligning SRAM memory maps, enhancing bootloader and test infrastructure, and improving cache coherency and power management. By focusing on device driver development, embedded systems, and configuration management, Bli delivered robust solutions that improved hardware readiness, data resilience, and runtime stability, demonstrating strong depth in low-level firmware engineering.

Dec 1, 2025December 2025: Implemented DMA-based ADC data acquisition across Apollo3 and Apollo510 with ISR-driven processing, overlay configuration, and test/support for low-power operation. Refined DMA/ADC handling to ISR-based processing and ensured complete shutdown of ADC interrupts on completion for stability and power efficiency. Expanded test and sample coverage with overlays to validate end-to-end data paths across boards.
