iMX6Q LPDDR2 MT42L128M64D2LL-25 IT_1 configuration problem

[selvakumarvelan]

Hi,

In our custom  iMX6q board we are using LPDDR2 MT42L128M64D2LL-25 RAM. The MMDC channels are configured by using the Mx6DQSDL LPDDR2 Script Aid V0.04-new.xlsx script. Please refer the attached script.

The DDR configuration is done thru DCD settings in our custom boot loader.

Now i load the DDR calibration tool (i.MX6/7 DDR Stress Test Tool V2.20) from my boot loader. The DDR calibartion binary image is started.

But while starting DDR calibaration it stops at Test Channel 0.

Also i attached the DDR stree test binary image log.

Let me know if i miss anything.

Thanks in advance.

Regards,

Selvakumar V
