******************************
=======DDR configuration==========
DDR type is DDR3
Data width: 16, bank num: 8
Row size: 14, col size: 10
Chip select CSD0 is used
Density per chip select: 256MB
==================================
What ARM core speed would you like to run?
Type 0 for 650MHz, 1 for 800MHz, 2 for 1GHz
ARM set to 800MHz
Please select the DDR density per chip select (in bytes) on the board
Type 0 for 2GB; 1 for 1GB; 2 for 512MB; 3 for 256MB; 4 for 128MB; 5 for 64MB; 6
for 32MB
DDR density selected (MB): 256
Calibration will run at DDR frequency 400MHz. Type 'y' to continue.
If you want to run at other DDR frequency. Type 'n'
DDR Freq: 396 MHz
Would you like to run the write leveling calibration? (y/n)
You have chosen not to run the write level calibration
Would you like to run the DQS gating, read/write delay calibration? (y/n)
Starting DQS gating calibration...
. . . . . . . . . . . . . . ERROR FOUND, we can't get suitable value !!!!
dram test fails for all values.
The DDR stress test can run with an incrementing frequency or at a static freq
To run at a static freq, simply set the start freq and end freq to the same valu

Hi Liang
you can check common guidelines
Freescale i.MX6 DRAM Port Application Guide-DDR3
regarding "DQS gating calibration.... . . . . . . . . . . . . . ERROR FOUND, we can't get suitable value !!!!"
first time you can just ignore it and continue to run remaining tests, just check if they will work.
This error is caused by excessive board noise, one can try to play with
drive strength settings (both i.MX6 and DDR memory), try different DDR_SEL options, use WALAT=1
and decrease operating frequency as much as possible.
Best regards
igor
