Hi T.F. and adding Alif as well. Long story short it fails on Altera trunk as follow: 1: Altera trunk force enable the driver of DESIGNWARE_WATCHDOG 2: It is not allow to remove by default git pull 3: After manually remove via Kconfig modification config TARGET_SOCFPGA_GEN5 bool # select DESIGNWARE_WATCHDOG 4: The DESIGNWARE and all CYCLIC are turned off DTS, .config had double confirmed the setup Test result: U-Boot SPL 2025.07-g35abb4f1cedc-dirty (Nov 28 2025 - 20:19:39 +0800) SDRAM calibration failed. ### ERROR ### Please RESET the board ### Long story short the inherent patch for this series is actually correct. The WDT introduces calibration failures. Thanks, Brian
