[Xenomai-help] xenomai on blackfin svn4240

Hello,
 
Starting from subversion revision 4240, xenomai is not compiling anymore
for blackfin.
I think that part of the problem is the absence of following parts in
usermode (I mean not __KERNEL__) in the file asm-blackfin/atomic.h :
 - typedef for xnarch_atomic_t is missing
 - xnarch_atomic_get is missing
 - xnarch_atomic_set is missing
 - xnarch_atomic_cmpxchg is missing
 
I also had to make the function xeno_init_current_mode (file bind.h) as
<<static inline>> to avoid a problem with multiple definitions when
linking my user-application (it includes functions of native and rtdm
library).
 
Finally rt_task_shadow fails and returns  EFAULT (but that problem can
be caused by my own dummy implementation for the functions mentioned)
 
Best regards,
Filip

The build woes should be fixed, but I still need to validate the trunk on a
bf561 here.

Hello Philippe,

Thank you for upgrading the blackfin code.  I upgraded to rev 4369 and
the compilation + booting the image works fine.
However, I am still having problems running programs with rt_task_shadow
(e.g. in examples/native/rtprint.c example).  Are you seeing similar
problems? (my platform is BF537 on Stamp)

Best regards,
Filip

I have a serious kernel issue here with 1.7-04 on a bf561, so severe that I
cannot actually run any app yet. I have a bf537 at hand as well, I think I'm
going to give it a try asap.

The issue you faced has just been fixed in the trunk. There is a new I-pipe
patch brewing here for the blackfin as well, since all patches from the 1.7
series are terminally broken when it comes to handling GPIO interrupts. The
bf537 does work because the EMAC ethernet IRQ is not on the GPIO demux, but the
ethernet interrupt of the bf561 is.

You should be able to run your bf537 just pulling the from the current trunk; I
will release an updated I-pipe patch later.
