Hello Champs,

 

From AN4467 i.MX 6 Series DDR Calibration, DQM looks to be evaluated during calibration in 64 bit operation.

 

"associated DQS, DQM signals (as well as DDR clock). DDR_PHY1 delay and status registers are used for calibration of DQ[63:32] and associated DQS, DQM signals."

How about in 32-bit operations?

Is DQM used in Sabre SDP?

 

BR,
