[rk1825]

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?

Thanks, Dave

DDR2 is used in our board with following clock configuration:-
Clock configuration:
  Coherent System Bus:  166 MHz
  Core:                 333 MHz
  Local Bus Controller: 166 MHz
  Local Bus:             41 MHz
  DDR:                  333 MHz
  SEC:                   55 MHz
  I2C1:                 166 MHz
  I2C2:                 166 MHz
  TSEC1:                166 MHz
  TSEC2:                166 MHz
  USB MPH:                0 MHz
  USB DR:                55 MHz
CPU: MPC8313E, Rev: 10 at 333.333 MHz
Board: S600 CPU BOARD
I2C:   ready
DRAM:  Initializing
   DDR RAM: 128 MB

ACR settings defined are as follows:- 
Arbiter pipeline depth (0-3)
Arbiter repeat count (0-7)
