Monthly summary for 2026-05 focused on USB networking reliability and driver architecture improvements in Nuttx (apache/nuttx). Delivered a lower-half architecture refactor for the USB Host CDC-ECM driver to improve modularity and performance by removing full network driver callbacks, and fixed critical transfer and MTU handling issues to increase stability in embedded USB networking.

April 2026 Nuttx USB subsystem milestones focused on expanding host capabilities, improving hardware compatibility, and stabilizing the STM32 USB driver stack. Delivered configurable USB host device selection, STM32H5 host mode support, and CDC-ECM host integration, along with targeted stability and compiler fixups.

October 2025 monthly update focused on PPP stability in apache/nuttx-apps. Restored the original LCP state management formatting and comments in PPP negotiation and fixed LCP_RX_UP handling during peer reconnection to align with expected PPP behavior. This maintenance work preserves protocol compatibility, improves connection stability, and reduces regression risk for embedded deployments.

March 2024 monthly summary for espressif/openocd-esp32: Delivered a targeted Cortex-M stack alignment and backtrace reliability fix in NuttX, addressing critical stack alignment issues and register offset calculations for Cortex-M targets. This improvement enhances debugging accuracy and reduces backtrace failures, aligning with the current NuttX version and OpenOCD integration goals.
