This is very strange,
I use ddr test run on sabrelite and on ott tv-box, and my custom board , all these works fine, but when I run ddr test on hdmi-dongle board, I can't pass DQS gating, read/write delay calibration. Why this happened? I have tried ddr test v1.0.3, the result is same. But when I run u-boot.bin in the board, and run command mtest, the board worksf fine. Here is the log.

Would you like to run the write leveling calibration? (y/n)
Please enter the MR1 value on the initilization script
This will be re-programmed into MR1 after write leveling calibration
Enter as a 4-digit HEX value, example 0004, then hit enter

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

Would you like to run the DDR Stress Test (y/n)?
Enter desired START freq (135 to 672 MHz), then hit enter.
Note: DDR3 minimum is ~333MHz, do not recommend to go too much below this.

Hi chuanyan
from log you used DDR script for "MX6Q_SabreSD" board
"SabreSD\RevC_and_RevB\MX6DQ\MX6Q_SabreSD
_DDR3_register_programming_aid_v1.5.inc"
also from log:
"MX6DL opened."
So really you are using different processor (MX6DL) and different board (hdmi-dongle).
You should obtain personal script for this board and processor using links below
and create script for this specific configuration ((MX6DL + hdmi-dongle board ).
