Fwd:Re: MPCI Layer problem

[Francesco Poletti]

Hy,
I have seen to the function _RTEMS_tasks_MP_Process_packet in the file
cpukit/rtems/src/taskmp.c. as Joel suggested: all seem works well...
I think that the problem may be in the formulation of the packet or in the
object table. If anyone can help me to found the formulation of the packet and
the object table structure I will be very happy! :-)
Tanks to all Francesco.

For each class of object, there is local and global object id
information.
It is maintained on each node.  The creation of that task should have
resulted
in an entry being added to the global object table for classic tasks on
the
other node.

See if you get to the RTEMS_TASKS_MP_ANNOUNCE_CREATE case lable in the
function _RTEMS_tasks_MP_Process_packet in the file
cpukit/rtems/src/taskmp.c.
