I see, my remembrance was somewhat wrong.
The Compiler (IAR EWARM 5.4 Kickstart) outputs a warning that the hex-File could not be deleted, but the Compiler is able to write the File. Very strange...
So the Problem is not as big as i thought
As previously reported, the warning disapears if FM is closed.
Compiler Output:
"Failed to delete C:\....\Debug\GettingStarted.hex "
I'am using FM 5.32 and WinXP SP2.
