9 Commits • 4 Features
Aug 1, 2025August 2025 monthly summary for flipperdevices/u-boot focused on consolidating hardware defconfigs, hardening boot-time checks, and improving platform readiness. Delivered VAB defconfig consolidation with CRC32 enablement and support for a larger kernel, added IOSSM mailbox compatibility check, disabled Agilex5 read cache to prevent hangs, fixed DDR calibration status polling, and advanced platform readiness with watchdog timer enablement, NAND controller addition for Stratix 10, and removal of hardcoded flash speed/mode values. These changes increase reliability, reduce runtime risks, and speed up production deployments across Agilex7, N5X, SoCFPGA, and Stratix 10 devices. Technical skills demonstrated: device tree tuning, defconfig management, DDR calibration, and hardware-boot reliability.
