Pc386 bsp problem

[Arquer Stephane]

Hi,

Effectively, 50 microseconds was originily set to generate a clock at 32Hz.
But I don't use it for the moment.

I changed this defines to avoid any other problems:
#define CONFIGURE_MICROSECONDS_PER_TICK	1000 
#define CONFIGURE_INIT_TASK_ATTRIBUTES	RTEMS_FLOATING_POINT + RTEMS_GLOBAL

The tasks are created to use floating point, I think the creation function tdemar is correct.

Attached, you 'll find the code I use.

Thanks.

Stéphane.
