OpenSDA Programming of KL25Z

Hello! I´m using MCUXpresso-IDE + Kinetis SDK to program a FRDM-KL25Z board. Now I have a problem:


When debugging out of MCUXpresso, everything works fine. When I build the program and copy the built *.sxf file onto the "FRDM-KL25Z"-named Flash-Drive, the older software (I debugged before) is executed and not the new one I copied onto the drive. Neither when hitting the reset-pushbutton, nor when repowering the board the new non-debugged software is executed.


The file I manually copy on the board is that one, when looking on the timestamp of the file it is the actual, correct build-version: MCUXpressoIDE_11.0.1_2563\workspace\Testprojekt\Release\Testprojekt.sxf


Anyone has an idea on this behaviour? Am I using a wrong way to program the device?


Kind regards,

Jan Martin
