Hello,

Greeting.

I have developed a customed IM6 Dual board with 2GB  DRAM(4 pieces MT41K256M16TW-107IT:P DDR3 chips by Micron).After configurating the DDR parameter,we tried DDR Stress test using DDR Stress test Tool V1.03 .The configuration progress stucked after starting DQS gating calibration,and the calibration didn't go any further.And it didn't report any "ERROR ".We also tried connecting the board with PC using a USB cabel ,the “MsgTools” can find a device,but  can't load the Uboot. We had reviewed the hardware design by "Check List".

 

 

Does anyone have any idea what I could be doing wrong or give me some suggestion? Thanks in advance for any help.
