[Xenomai] Mercury 3.0.2 on Raspberry Pi 3

[dominikk <dominikk@openmailbox.org>]

Hi there,

we are trying to run the Mercury core on a Raspberry Pi 3. The code
compiles fine and the latency test (/usr/xenomai/bin/latency) runs
successfully.

However, running a dummy application (i.e. Hello World) results in the
following error:

# sudo ./test
   0"003.571| WARNING: [main] failed to initialize multi-threading
              package
   0"003.791| WARNING: [main] setup call copperplate failed
   0"003.925| BUG in xenomai_init(): [main] initialization failed, 22?

Similarly, when running alatency:

# sudo /usr/xenomai/demo/altency
   0"003.571| WARNING: [main] failed to initialize multi-threading
	      package
   0"003.791| WARNING: [main] setup call copperplate failed
   0"003.925| BUG in xenomai_init(): [main] initialization failed, 22?

Same results for hdb or any other application linked with the Alchemy skin.

We are running (raspberry) Kernel 4.4.13 with RT patches and compiled
xenomai with the following flags:

Build args:
CFLAGS=-march=armv7-a -mfpu=neon-vfpv4 -mfloat-abi=hard
LDFLAGS=-march=armv7-a -mfpu=neon-vfpv4 -mfloat-abi=hard
--with-core=mercury --disable-debug --enable-clock-monotonic-raw
--enable-smp

Any advice would be greatly appreciated.

Regards,
Dominik
