I have problems with floating point calculations. When I do this simple test the floating point calculation complete failed.
1: Create a Generic Application with the Freescale Beekit 1.9.8 and codebase ARM7 SMAC 1.1.2
2: Set the security option in the property list tab
3: Export the solution to IAR 5.20
I use the terminal I/O screen in the view menu to watch the debug messages.
4: Go to the options windows and change the follow options.
a) General Options > Library Configuration > Library low-level interface implementation to Semihosted
b) General Options > Library options > Printf formatter to Full.
5: Add the follow lines to the generic_app(void) function
printf("Test float 1 %2.2f\n\r", 142.567);
printf("Test float 2 %2.5f\n\r", 67.52);
printf("Test float 3 %2.2f\n\r", 9.3332);
printf("Test float 5 %4.2f\n\r", 9372.43);
6: Download and debug the application to a MC13224v development board.
7: Now open the terminal I/O windows and watch the result. I get the follow strange ouput.

When I do the same test with the MAC codebase project, I got the same result. Why doesn't this work?
