The DDR controller and DDR PHY have a large number of parameters to configure. To facilitate the configuration, an online tool (SysConfig tool) is provided that generates an output file consumed by the driver. Choose DDR Subsystem Register Configuration from the Software Product pulldown menu and choose the required processor. This tool takes system information, timing parameters from DDR device data sheet, and IO parameters as inputs and then outputs a header file that the driver uses to program the DDR controller and DDR PHY. The driver then kicks off the full training sequence.
The SDK will have an integrated configuration file for the device mounted on the EVM. If you need a configuration file for a different device, you need to generate the new configuration file with the DDR Register Configuration tool.
