August 2025 monthly summary for geerlingguy/linux focusing on reliability and hardware compatibility improvements in the NAND subsystem. Key features delivered: - NAND read timing reliability improvement: NRD_SETUP now uses the maximum of tAR and tCLR instead of a fixed zero to ensure proper detection and reliable reads on affected Toshiba TC58NVG2S3ETAI0 and similar NAND chips. This change aligns with existing timing specs and reduces read failures in affected hardware. Major bugs fixed: - Bug fix in NAND read timing path preventing unreliable reads on affected chips by adjusting NRD_SETUP calculation (tAR/tCLR) as the maximum value, ensuring robust operation across the impacted devices. Commit: fd779eac2d659668be4d3dbdac0710afd5d6db12. Overall impact and accomplishments: - Enhanced data integrity and system reliability for storage read paths across affected NAND devices. - Improved hardware compatibility and reduced read-related field issues, contributing to lower support load and higher customer satisfaction. - Clear risk reduction in NAND path timing through precise timing parameter handling and alignment with chip specifications. Technologies/skills demonstrated: - Linux kernel NAND driver development and timing parameter calculations. - Hardware-aware software engineering, patch creation and review, and managing compatibility across chip variants. - Proven ability to identify, verify, and fix critical reliability bugs with measurable business value.

Monthly development summary for February 2025 focused on the u-boot repository work and bug fixes.

January 2025: Focused work on the U-Boot bootloader for Capricorn CXG3. Implemented Watchdog Timer (WDT) support and improved debugging capabilities for hardware watchdog across Capricorn CXG3 platforms. Delivered with a clean commit and streamlined board configuration.

December 2024 monthly summary: Focused on stabilizing networking initialization in U-Boot for flipperdevices, specifically preventing gigabit advertisement on MII/RMII interfaces to ensure reliable connectivity and reduce negotiation timeouts across hardware revisions.

November 2024: Completed watchdog timer cleanup in the U-Boot driver for flipperdevices/u-boot, removing an obsolete clock-rate hack and aligning WDT behavior with Linux kernel fixes to ensure reliable timeout semantics.
