This indeed helped me, while no success yet: U-Boot SPL 2024.01-rc1-45362-g94a35b52f78-dirty (Feb 24 2025 - 17:31:47 +0300) mxstatus=0xc0408000 mhcr=0x0000010b mcor=0x00000003 mhint=0x00004000 Trying to boot from SPI fdt_fixup_memory_banks: FDT_ERR_BADMAGIC Failed to update DTB resetting ... reset not supported yet ### ERROR ### Please RESET the board ### > > Cheers, > Quentin -- With best regards, Matwey V.
