We have a custom board for which we refferred SABRESD reference Schematics.In our Board we change the RAM to Micron MT41K256M16TW-107 DDR3 RAM.We have two variants of custom board ,in which one is running on i.MX6 solo with 1GB RAM and another with i.MX6 Dualite with 2GB RAM.
I have done the DDR calibration for both the boards but I have following issues:
1) In solo board I am getting only 4 values from calibration(I have done the calibration multiple times).
2) After looking into others DDR3 configuration I modified my DDR3 configuration for solo but I am getting kernel panic issues continuously.
Is it necessary to run the DDR stress Test for setting up DDR3 settings properly?
I this script I am not getting Data rate option as 1866 (its lasts to 1600) and also I am unable to edit tRCd ,tRC,tRAS values.
Do I need to change Si configuration values?
Kindly help regarding this issue.
