    Not sure what you are referring to in above question.

    We have a debug binary that can dump training values. We ask customers to run it when they are having DDR initialization issues. There is no report associated with it.

    What do you plan to do with the training values?

    Q2, how can we do the DDR stress test? what is the command?

    Q1: we want to optimize our simulation by comparing to the training values, can you share the debug binary that dumps the training value? how to identify the parameter value from dumped data?
