Dear stefan.
I Made my board config header, and using yosemite's init.S & u-boot.lds, mft.c(Yosemite.c) Only change config header , but it's not working .
1. First The difference of my SDRAM configuration is *** (PPC440EP supported four external DDR_SDRAM Banks.) *** But Our used only external DDR_SDRAM Bank_0(BANKSEL_0) on the New design Board.
2. Second my config header is Include/configs/mft.h ________________________________________________________________________________________ #define CONFIG_440EP 1 /* Specific PPC440EP support */ #define CONFIG_HOSTNAME mft
#define CONFIG_440 1 /* ... PPC440 family */ #define CONFIG_4xx 1 /* ... PPC4xx family */ #define CONFIG_SYS_CLK_FREQ 66666666 /* external freq to pll */
#define CONFIG_BOARD_EARLY_INIT_F 1 /* Call board_early_init_f */ #define CONFIG_MISC_INIT_R 1 /* call misc_init_r() */ #define CONFIG_BOARD_RESET 1 /* call board_reset() */
/*----------------------------------------------------------------------- * Base addresses -- Note these are effective addresses where the * actual resources get mapped (not physical addresses) *----------------------------------------------------------------------*/ #define CFG_MONITOR_LEN (512 * 1024) /* Reserve 512 kB for Monitor */ #define CFG_MALLOC_LEN (256 * 1024) /* Reserve 256 kB for malloc() */ #if 1 //steven #define CFG_MONITOR_BASE (-CFG_MONITOR_LEN) #else #define CFG_MONITOR_BASE TEXT_BASE #define CFG_SDRAM_BASE 0x00000000 /* _must_ be 0 */ #define CFG_FLASH_BASE 0xfc000000 /* start of FLASH *
... /*----------------------------------------------------------------------- * DDR SDRAM *----------------------------------------------------------------------*/ #undef CONFIG_SPD_EEPROM /* Don't use SPD EEPROM for setup */ #if 0 //steven #define CFG_KBYTES_SDRAM (128 * 1024) /* 128MB */ #else #define CFG_KBYTES_SDRAM (64 * 1024) /* 128MB */ #endif #if 1 //steven #define CFG_SDRAM_BANKS (2) #else #define CFG_SDRAM_BANKS (1) #endif
define CONFIG_SDRAM_BANK0 1 _________________________________________________________________________________________
The difference of your SDRAM configuration?
Best Regards. Steven

I’m using u-boot1.1.3 with Yosemite configuration.
Please use the latest version from the DENX git repository.
When I boot with Yosemite conf , it stops SDRAM:256 , it’ shows cpu, pci conf
So it most likely crashed upon relocation into SDRAM. So its an SDRAM configuration problem.
My New Board configuration is only different SDRAM Size and Flash Size.
Where can I modify my Yosemite configuration.
Init.S and Yosemite.h
Yosemite uses a board specific SDRAM init routine. I suggest that you use the common DDR2 init code by enabling it in your board config header (include/configs/board.h):
#define CONFIG_SDRAM_BANK0 1 /* init onboard DDR SDRAM bank 0*/
You can also define CONFIG_SYS_SDRAM_TABLE if you have an uncommon SDRAM configuration. What's the difference of your SDRAM configuration?
Best regards, Stefan
