Marginal issues on CA, Write DQ/DQS, or Read DQ/DQS. When the Write Calibration training fails, a dialog box appears as shown in the following figure.Figure 5-16. Write Calibration Training
Workaround
Configure any one of the following parameters to a different value using the MSS Configurator when the Write Calibration training fails:
FPGA DQ Drive
FPGA DQS Drive
FPGA DQ ODT
FPGA DQS ODT
Memory Output Drive Strength
The following figure shows the configuration of the DQ/DQS drive or ODT in the DDR Controller tab.Figure 5-17. Configuring DQ/DQS Drive or ODT—DDR Controller TabThe following figure shows the configuration of output drive strength in the DDR Memory Initialization tab.Figure 5-18.
