3.2 CMD/ADDR to REF_CLK Training Fail

Possible Reason
Signal integrity issues on CA. When CMD/ADDR to REF_CLK training fails, a dialog box appears as shown in the following figure.
Figure 3-5. CMD/ADDR to REF_CLK Training Fail
Workaround
Configure any one of the following parameters to a different value using the MSS Configurator when CMD/ADDR to REF_CLK (CA/CK) training fails:
  • Memory CA ODT
  • FPGA ADD/CMD Drive
The following figure shows the configuration of CA ODT in the DDR Memory Initialization tab.
