Unexpected trap (0x04) fp disabled

Hi all.

 

I have tried to run a simple test in sparc-rtems-gdb and I get the
following error:

 

Unexpected trap (0x04) at address 0x40004ee8

fp disabled

 

The backtrace shows:

 

Program exited with code 0362.

(gdb) bt

#0  syscall ()

    at
../../../../../../../../rtems-4.6.5/c/src/lib/libcpu/sparc/syscall/sysca
ll.S:54

#1  0x40003ba8 in DEBUG_puts (string=0xf2000fe7 "")

tup/spurious.c:122

#3  0xa5a5a5ad in ?? ()

#4  0xa5a5a5ad in ?? ()

Previous frame identical to this frame (corrupt stack?)

 

I thought it was because of I didn't put the floating point attribute
for the rtems task but it still fails with the same error.

 

#define CONFIGURE_INIT_TASK_ATTRIBUTES RTEMS_FLOATING_POINT

 

I don't know if there is any error in the thread creation with
pthread_create or anything else.

 

Thanks for your help

Patricia
