Hello Jami, For DDR size problem, I think we could enable CONFIG_OF_BOARD_SETUP, then use ft_board_setup() to apply fdt_fixup_memory()? Just like what they did in spl.c: https://patchwork.ozlabs.org/project/uboot/patch/20230615093652.23161-12-yanhong.w...@starfivetech.com/ Best regards, Shengyu (This mail is sent twice because the first one didn't use reply all)
