We use DDR tool 2.1 to tuning our new LPDDR4 memory on iMX8MQ. That pass the Calibration, and do the stress test, the result is fail. When we check "Disable DDR Memory Cache", and retest again, it pass. Then we direct use "Gen Code" and compiler with uboot, the result is my system sometime boot success and sometime boot fail on memory panic. Have any thing we can change on DDR tool or ds file?
