We got a problem that uboot of our board seems not work right.
Our host system is Centos 6.3, and we use minicom to connect our board through 232 port.
But it seems have some problem with the message print as below:
U-Boot 2011.12-00025-gc6d9d50 (Mar 17 2013 - 11:09:26)

Error reading i2c boot information!
DRAM: DDR: failed to read SPD from address 82
Error in DDR bus width configuration!
16 MiB (DDR2, 64-bit, CL=0.5, ECC off)
And the printing is just stop there, it seems that DDR3 on board is not detected.
The uboot file is fine that we got it right on another RDB borad in July, is this a hardware issue?
Is there anyone got similar problem? Please help!
Thanks in advance.
