I am using a custom board with MPC8313E processor. In u-boot prompt, when i
do TFTP of large size files, sometime it hangs completely and, sometimes it
says bus fault, prints following message and resets the board.

Did you have one stable memory system?
What is the clock information? Such as core/csb/ddr data rate?
What is the ACR value?
