[U-Boot-Users] I cann't initialize OR/BR registers in cpu_init.c?

hello ! all I'm porting u-boot-0.4.0 to my WindRiver MDP PRO board now,some addressing specifications are listed below.I choose the

fads823 as the model.I have vision ICE ii & vision CLICK to program flash and debug the code. I compile the code in the vmware linux environment.After "make myboard_config" and "make",I copy the u-boot(ELF) to the

vision CLICK path in windows environment，then Convert to .BIN file, program to flash,run,use the hyperterminal as the

console. Now in the cpu_init.c ,I masked all the OR/BR initialization clause,for when I released them there's nothing displayed on

the hyperterminal ;but when masked them ,the program can run to the "=>"(after main_loop();)with the vision ICE II and to the

relocate_code()(in the board_init_f();)without the visionICE II ,some register value are listed below in the vision CLICK BKM

mode.

**1.why I cann't initialize the OR/BR registers in the cpu_init.c **2.how to modify the dram initialization to pass the relocate_code() 3.can you tell me something details about the BCSR register in the FADS823 model. 4.are there any better model for WindRiver MDPRRO board ?

Any suggests are very appreciated!

specifications: Addressing: Total address range 4GB (on and off board) Flash Memory 1.0MB on board 16MB SIMM (4MB Std.) SRAM Memory 2MB (512K Std.) DRAM Memory 32MB SIMM (16MB Std.) EEPROM 8K
