GUI Flash Tool, Flashing in specified area

[jens_wagner]

I am using the KM34Z256VLL for a metering application.

My question is about the GUI Flash Tool.

I have calibration data in a separated flash area (3f800 - 40000) that must not be deleted, but I would like to flash altered firmware on the device. Is it possible to flash until a certain address without deleting the rest? Technically this should work, but I can't find out how to do this. (Maybe with the "Additional Options" in the GUI Flash Tool)
