1.17.4. Stage 1: Read Calibration Part One—DQS Enable Calibration and DQ/DQS Centering Read calibration occurs in two parts. Part one is DQS enable calibration with DQ/DQS centering, which happens during stage 1 of the overall calibration process; part two is read latency minimizat...
Before the write calibration, the deskew calibration algorithm performs a guaranteed write, and then sweeps dqs_in delay values from low to high, to find the right-hand edge of the read window. The algorithm then sweeps dq_in delay values from low to high, to find the left-hand edge of...
NV-DDR3 introduced several calibration techniques, including ZQ Calibration, Duty Cycle Correction (DCC) and read/write DQ Calibration. As mentioned above, ONFI 3.0 introduced

Error: failed during ddr calibration Is it possible that JTAG somehow influences DDR operation? Or maybe there are some hardware constrains for JTAG to successfully operation with i.MX6? One other question is about Register Programming Aid v2.4 for IMX6DQ. We have 4 DDR3 chips all connecte...
Refer to 44.12.46 MMDC PHY Read DQS Gating Control Register 0 (MMDCx_MPDGCTRL0) in MCIMX6DQRM(Rev.2). Are these below description typo?? 1. Supported Mode Of Operations: === For Channel 0: DDR3_x16, DDR3_x32, DDR3_x64 For Channel 1: DDR3_x64 === 2....
In another embodiment, the output of calibration register 270 is received at a node that also receives an output from data input buffer 205. From this point, the DQtest signal travels though the data delay 247 to the input timing device 250, which has an output on line 252 coupled with ...
