I´m new with the Kinetis Controllers and I get a problem with the Interrups.

I´m using the IAR Workbenck and a Jlink programmer.


If I put my software on an MKL03Z8VFG4 every time a interrupt is triggert the controller jumps to an not used flash adress.

I have check with the TMP0, TMP1, LPTMP0 and the ADC interrupt.

If the interrupt is not triggert the programm work fine.

The same Software on the FRDM-KL03Z Board have no problems.


I check the map file and see the IQR Handler on the correct position.


Have somebody an idea about this problme?
