I disabled the 2nd core by using "cfg_core1_enable" and D2_MSRCID1 signal is not connected and we are using DDR controller 2... will this create any obstacles to relocate? Is there any other register configuration for DDR? can somebody help me to understand this or give me some pointer to get more understanding for this... I am getting frusted because I am stuck at this point from last 20 days. please help... thanks in advance and Regards

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

sleep 200
writemem.l 0xf8006110 0xC3088008 # DDR_SDRAM_CFG
but I did not understand... can you give some light on this.
thanks again...

It is probably because your DDR wasn't initialized correctly. You can try to dump all DDR registers and check if anyone is suspicious. You can also override any register before enabling the controller.
You may also add some memory test before relocation.

hii I am using MPC8641D based custom board for evaluation purpose. I am using minimal configuration for this board i.e. only FLASH and DDR initialisation. when I compiled U-boot in debug mode its printing addresses, i check for those addresses and found that it is unable to relocate itself to DDR(4*MT47H64M16). The following message was
