Workaround

Configure any one of the following parameters to a different value using the MSS Configurator when the Write Calibration training fails:

Memory CA ODT
FPGA DQ Drive
FPGA DQS Drive
FPGA DQ ODT
FPGA DQS ODT
Memory Pull-Down Drive Strength

The following figure shows the configuration of DQ/DQS drive or ODT in the DDR Controller tab.
