Hi everyone,

 

Our custom imx6Q board all functions/components are workable.(The ddr use MT41K128M16*4)

Now, we want to use MT41K256M16(DDR3-1866) instead of MT41K128M16 that imx6Q use it on demo board.

The ram size upgraded from 1GB to 2GB. (MT41K256M16*4)

 

We referenced https://community.nxp.com/docs/DOC-105652 and http://www.imx6rex.com/software/how-to-run-ddr3-calibration-on-imx6/

 

As we used GUI_DDR_TEST_TOOL v2.5.2 or DDR_STRESS_TESTER v1.0.3 to test MT41K256M16, we got some problem as below

We are receiving an error message - " Failed to send calibration command".

But, we used GUI_DDR_TEST_TOOL v2.5.2 to test MT41K128M16 on our custom board, it was successful.

 

 

Here is our setting parameter for MT41K256M16 (Memory type: DDR3-1866)

About MT41K256M16 parameter is as below. (256Meg x 16)

We also tried to use DDR_STRESS_TESTER v1.0.3, but it doesn't work either.

Could you can give me some advice?
