To build a u-boot for danube board, user need to do the following things:
|
|
To configure u-boot for a proper board, user need to modify two files accordingly.
|
|
|
|
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
|
|
