It contains the information on which pages need updating. This is the source of the report that clupdate generates showing the number of pages requiring an update. During the FLUPD process, the CFLDB that resides on the 41CL is updated as each sector is written, so that at the end of the update if you inspected it you would find that all of the updated pages were now marked as unverified. Normally the CFLDB does not need to be retained after an update completes. The only real use for the information it contains is during the update process. So it is nice to have if the update is aborted for some reason, but that is all. Once an update completes properly, the FLDB in Flash memory corresponds to the contents of the Flash and the next update does not need to bother with calculating the CRC on every page. This is why I added the CPONLY option. If you start messing with the contents of Flash, then all bets are off and you should probably run the FLCHK? in the normal mode. Hope this helps. Monte |
