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 /* ...

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?
