March 2026: Delivered IS25WP01GG SPI NOR flash support in U-Boot (MTD: spi-nor-ids). Added a new flash ID entry (ID 0x9d7021) describing 64KB sectors and 2KB page size, with 4K sector support and dual/quad read. Changes validated on N5X boards and aligned with the IS25WP01GG datasheet. Business value: broader hardware compatibility for boot and storage across supported devices, reducing hardware risk and accelerating onboarding of new platforms. No major bugs fixed this month; efforts focused on reliable feature delivery, code quality, and test coverage. Technologies demonstrated: embedded SPI-NOR handling, MTD subsystem integration, device identification, cross-board testing, and documentation.

February 2026 monthly summary for flipperdevices/u-boot: Implemented a bug fix for Cadence XSPI to auto-allocate platform data, stabilizing SPI probe initialization across multiple controllers. This change prevents probe failures by ensuring proper IOBASE/SDMABASE/AUXBASE values and correct cdns_xspi_plat sizing via plat_auto. The fix was tested on an Altera Simics platform with multiple XSPI controllers and is expected to reduce downtime in hardware bring-up. Technologies demonstrated include Linux kernel SPI driver debugging, Cadence XSPI integration, and platform data handling. Business impact: higher reliability and faster hardware initialization, reducing maintenance overhead and facilitating multi-controller deployments.
