RTEMS objects have a static allocation scheme. The "too_manny" error
signals, that you cannot create a new object because it would exceed the
object storage. In your case, either the "maximum devices" (most
probable) or "maximum_drivers" or "number_of_device_drivers" entries
should be increased, see your "system.h" file and the "confdefs.h" which
is included there.

Thomas.
