Subject: [Xenomai-help] FPU not available in user-space programs
Date: Thu, 06 Jul 2006 00:33:22 -0300	[thread overview]
Message-ID: <44AC8482.6000902@domain.hid> (raw)

Hi,

I was looking at /proc/xenomai/faults and noticed that the only errors 
were on TRAP 7 (FPU not available).

Each time I run the user-space program using the native skin, I 
increment the fault by one. I don't understand why this happens. From 
documentation, FPU should be enabled automatically for user-space programs.

Any ideas why I'm getting this error and what does it mean? Should I do 
some float-point operation before creating my real-time tasks?

Thanks in advance,

Rodrigo.
