Thanks For reply, i check DDR configuration using Code warrior, and successfully getting read/write from DDR. I use the following configuration in code warrior and same in u-boot... writemem.l 0xf8006000 0x0000001f # CS0_BNDS writemem.l 0xf8006080 0x80914102 # CS0_CONFIG writemem.l 0xf8006100 0x00070000 # TIMING_CFG_3 writemem.l 0xf8006104 0xFF770F0F # TIMING_CFG_0 writemem.l 0xf8006108 0x7F78F777 # TIMING_CFG_1 writemem.l 0xf800610C 0x00205114 # TIMING_CFG_2
writemem.l 0xf8006110 0x43088008 # DDR_SDRAM_CFG writemem.l 0xf8006114 0x24401000 # DDR_SDRAM_CFG2 writemem.l 0xf8006118 0x43800E52 # DDR_SDRAM_MODE writemem.l 0xf800611C 0x8000C000 # DDR_SDRAM_MODE_2 writemem.l 0xf8006120 0x00000000 # DDR_SDRAM_MD_CNTL writemem.l 0xf8006124 0x05080000 # DDR_SDRAM_INTERVAL writemem.l 0xf8006128 0x00000000 # DDR_DATA_INIT writemem.l 0xf8006130 0x03800000 # DDR_SDRAM_CLK_CNTL sleep 200 writemem.l 0xf8006110 0xC3088008 # DDR_SDRAM_CFG but I did not understand... can you give some light on this. thanks again...
