To start the utility in Catch-Up Mode

Enter the command:

mnand_rfsh -d <dev_path> -p <file_path>
-C <time_msec> [-t <date_time>] [-m time_sec] [-y days] [-v verbosity]

The utility attempts to ensure that the mNAND device is refreshed within the time specified by the –m parameter, as described in Algorithm for Converging to the Refresh Schedule. The utility issues a refresh command every <time_msec> milliseconds until the desired refresh progress is achieved, or the run time specified by <time_sec> expires.
