Floating point issue in rtems 4.8.2 when running on TSIM

[Óscar Álvarez Paredes]

Hi,

I have the following files in rtems 4.8.2.

It compiles Ok, but when I run it on TSIM it gives the following error:

TSIM/LEON SPARC simulator, version 2.0.15 (professional version)

Unexpected trap ( 4) at address 0x40001584
fp disabled

Program exited normally.

It seems as if the fp was no enabled at RTEMS level, but as you can see in the init.h file I have:
#define CONFIGURE_INIT_TASK_ATTRIBUTES RTEMS_FLOATING_POINT

Any idea why?

Thanks,

Oscar
