Read Gate Training Fail
Workaround
Configure any one of the following parameters to a different value using the MSS Configurator when the Read Gate training fails:
Memory CA ODT
Memory Pull-Down Drive Strength
FPGA DQS ODT
The following figure shows the configuration of pull-down drive strength or CA ODT in the
DDR Memory Initialization
tab.
