Monthly summary for 2026-04 focusing on feature delivery for the peterbarker/ardupilot repository: Key features delivered: - FM25Q-series flash memory support and configuration implemented across the system (AP_FlashIface, AP_Logger, AP_Filesystem). This includes JEDEC ID integration (0xA1) for Shanghai Fudan Microelectronics FM25Q64/128/256 and alignment of device recognition and interfacing. - LittleFS storage configuration updated with block counts for FM25Q64/128/256 to ensure reliable storage allocation and compatibility with larger flash parts. Major bugs fixed: - No separate critical bug fixes were recorded for this feature scope in April; work focused on feature expansion and correct device recognition/configuration to prevent storage-related issues. Overall impact and accomplishments: - Expanded hardware compatibility and storage reliability for FM25Q-series NOR Flash, enabling easier onboarding of larger flash devices and reducing integration effort for future models. - Improved stability of storage-related operations by ensuring proper JEDEC identification and correct block sizing within LittleFS, reducing risk of misdetection and data corruption. Technologies/skills demonstrated: - Embedded C/C++ development, flash memory interfacing, and filesystem integration (LittleFS). - JEDEC standard ID handling, device recognition, and cross-module configuration (AP_FlashIface, AP_Logger, AP_Filesystem). - End-to-end traceability with commit-level changes supporting the feature delivery.
