To configure u-boot for evaluation board, in danube-uboot/include/configs/danube.h, set #define USE_EVALUATION_BOARD #undef USE_REFERENCE_BOARD and vice-versa. To let u-boot boot from ebu(flash,e.g), in danube-uboot/include/configus/danube.h, set #define DANUBE_BOOT_FROM_EBU Otherwise u-boot will be compiled for booting from RAM. To use DDR RAM running at 111M, in danube-uboot/include/configus/danube. h, set #define DANUBE_DDR_RAM_111M #undef DANUBE_DDR_RAM_166M and vice-versa. To define RAM size of RAM, in danube-uboot/include/configus/danube. h, set #define RAM_SIZE 0x2000000 /*32M ram*/ This is an example for a 32M RAM. Besides above settings, user need to change danube-uboot/board/danube/config.mk to set the loading address of u-boot. If U-Boot is to boot from EBU(flash), user needs to set TEXT_BASE=0xB0000000 If u-boot is to boot from RAM, user needs to set TEXT_BASE=0xa0400000 Use the script gct to build a uart downloadable u-boot image: ./gct danube_ref_ddr166.conf u-boot.srec u-boot.asc
