I heard QorIQ Configuration Suite (QCS) support read adjust method
(read leveling) as following.


Automatic CAS to preamble calibration:


Instead of JEDEC’s MPR method, Freescale controllers use a

proprietary method of read adjust method. Auto CPO will provide the

expected arrival time of preamble for each strobe line of each byte

lane during the read cycle to adjust for the delays cased by the fly-by



Does DDR calibration tool for i.MX6* also support this feature?


* such as:
     i.MX6/7 DDR Stress Test Tool V2.20
     i.MX6 DDR Stress Test Tool V1.0.3
