After searching source code,I have 3 questions: the first,board "EVB64260" may be the best suitable to mine? the second,In evb64260.h, BAT of SDRAM is: /* SDRAM */ #define CFG_IBAT0L (CFG_SDRAM_BASE | BATL_PP_RW | BATL_CACHEINHIBIT) #define CFG_IBAT0U (CFG_SDRAM_BASE | BATU_BL_256M | BATU_VS | BATU_VP) #define CFG_DBAT0L (CFG_SDRAM_BASE | BATL_PP_RW | BATL_CACHEINHIBIT | BATL_GUARDEDSTORAGE) #define CFG_DBAT0U CFG_IBAT0U I found attribute of SDRAM is not BATL_GUARDEDSTORAGE in some board configuration file,and some others is not BATL_GUARDEDSTORAGE.And I think SDRAM should not be BATL_GUARDEDSTORAGE,right? The last question is when I using Windriver ICE debug u-boot,after I run program to set MMU,CPU_SDRAM,CPU_DEVICE registers,Workbench Register window display correct number of MMU,but display all "ffffffff" of CPU_SDRAM,CPU_CONFIGURATION.when I "RUN" u-boot in flash,it stop and run into address 0x800 exception program.Anyone can direct me how to explain it? Thank you very much!Hope reply. -- View this message in context: http://www.nabble.com/questions--about-porting-to--MPC7410%2BEVB64260-tp16418464p16418464.html Sent from the Uboot - Users mailing list archive at Nabble.com.
