Feb 1, 2026February 2026 (OpenSiFli/SiFli-SDK) focused on stabilizing the WiFi module initialization path and reducing SDIO latency. Delivered a bug fix that resolves system freezes during WiFi init by addressing initialization thread mutex contention and shortened the SDIO wait window from 5 seconds to a few hundred milliseconds. These changes improve boot reliability and WiFi readiness, reducing mean time to repair (MTTR) and enhancing user experience for devices relying on SiFli-SDK. Commit 07459a52bf3c59910325c2d348335d08ec65083ff was applied with detailed SDIO wait-logic improvements.

Jan 1, 2026January 2026 (OpenSiFli/SiFli-SDK) performance and delivery snapshot focusing on hardware add-ons, WiFi reliability, and driver robustness. Key features delivered include: 1) WiFi support improvements with wake-up pin configuration and module integration, plus a comprehensive README for the Wi‑Fi example to accelerate customer adoption; 2) I2C EEPROM example board support updated to add sf32lb56x, widening hardware compatibility; 3) New board configuration sf32lb55-lcd_n16r4n4 with LCD and touch panel initialization, Kconfig, and source changes to enable ready-to-use LCD/touch workflows. Major bugs fixed: SDHCI driver DMA data buffer address handling corrected to use the SBUS address (starting at 0x60000000), improving stability of SD host operations under SBUS addressing. Overall impact and accomplishments: Expanded multi-board support and robust WiFi integration, enhanced developer/docs experience, and improved driver reliability. These changes reduce integration friction for customers onboarding new hardware variants and increase correctness of memory addressing in the SDHCI path, contributing to lower field incidents and faster time-to-value. Technologies/skills demonstrated: embedded C/driver development, kernel-like subsystems (SDHCI, I2C, WiFi), Kconfig and board-level configuration, hardware-software integration, and clear documentation for developer adoption.
