  Figure 3-1.ODT is not Turning ON

Workaround
  Configure any one of the following parameters to a different value using the MSS Configurator when ODT does not turn ON:
  - Memory CA ODT
  - FPGA ADD/CMD Drive
  - FPGA Vref CA
  The following figure shows the configuration of CA ODT in the DDR memory Initialization tab.
