Ok, I have checked the code, Xenomai uses the same macros as Linux, which handle the various versions (armv5, armv6, VFPv3), so, it should work. Could you send me (privately) the disassembly of pod.o, you should find it somewhere in the sub-directories of the compiled linux kernel. Alternatively, send me pod.o itself. -- Gilles.
