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)
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?
