Now its working... by default the data width of bus was 64bit and ddr2
was configured for 32-bit.. so i change the data width and now its
working...
Thanks a lot for lighting up the path...
now i am trying to configure like CPU:1200 MHz, MPX:600 MHz DDR:300
MHz (600 MT/s data rate) but i its stucking before relocation... its
working file at DDR 250Mhz.. is it because DDR or FLASH configuration.??
Thanks again and Regards
