Tom, that could be the case if it's only me, but this has been reported by other users as well. This is my PICkit config: <PICkit2PlatformTool> <property key="pk2settings.3state" value="false"/> <property key="pk2settings.preserveee" value="true"/> <property key="pk2settings.setvddvoltage" value="5,00"/> <property key="pk2settings.userpgmexec" value="true"/> <property key="pk2settings.usetargetpower" value="false"/> </PICkit2PlatformTool> The "5.00 V" setting is marked red with "!!" and "Unknown cause" by the MPLAB config UI -- I don't know what that means.

I've never had anything like that happen and I've flashed my device plenty of times when doing occasional coding. I have blasted it to all zeros a few times, which I attribute to forgetting to flip that setting either in the MPLab project or in the PICkit2 downloader.
Perhaps you have a bad chip or a bad programmer?
Very curious.

Hi all,
my PICkit2 frequently alters single EEPROM cells on flashing. It's set to "preserve EEPROM" and mostly does so, the effect only for example changes the server parameter from "64..." to "S4...".
Other parameter slots also have been affected, my last flash changed my registered phone id, and a forum member reports a change of the first vehicle id byte from "D" to "R".
Is there a way to make the flashing process reliably preserve the EEPROM?
Thanks, Michael
