Here is what I did (on a fresh Raspberry Pi 2 B)
$ uname -a
Linux raspberrypi 4.1.13-v7+ #826 SMP PREEMPT Fri Nov 13 20:19:03 GMT 2015 armv7l GNU/Linux
$ curl get.pharo.org/50 | bash
$ wget
http://files.pharo.org/sources/PharoV40.sources.zip$ wget
http://files.pharo.org/vm/pharoS/raspbian/latest.zipBoth the PharoS and squeak VM that comes with Raspbian 7 fail (not Spur compatible):
$ squeak -nodisplay Pharo.image printVersion
found gettext in path
/home/pi/Pharo
This interpreter (vers. 0) cannot read image file (vers. 6521).
Press CR to quit...
pi@raspberrypi ~/Pharo $ ./pharosvm/PharoS -nodisplay Pharo.image printVersion
unknown option: -nodisplay
$ ./pharosvm/PharoS --nodisplay Pharo.image printVersion
This interpreter (vers. 6505) cannot read image file (vers. 6521).
Press CR to quit...
The Cog VM does work:
$ ./cogspurlinuxhtARM/lib/squeak/5.0-3427/squeak -nodisplay Pharo.image printVersion
[version] 5.0 #50581
It is way faster than PharoS on an older B+.
But it does have an annoying slowdown in shutting down: it starts up OK, executes its eval expression immediately, but then seems to wait a couple of seconds before shutting down:
pi@raspberrypi ~/Pharo $ echo `date`; time ./cogspurlinuxhtARM/lib/squeak/5.0-3427/squeak -nodisplay Pharo.image eval 'DateAndTime now'; echo `date`

real 0m7.415s
user 0m7.210s
sys 0m0.250s
Sat Feb 13 15:45:51 UTC 2016
This takes 7 seconds, while the DateAndTime now is printed just .86 seconds after starting.
Running an HTTP server worked fine. I will try to get my actual app running and then test OS(Sub)Process.

PS: it is a bit odd that the latest Cog VM was published in August, nothing new since then.

Note that the new FFI, even if it reuses the VM FFI backend, is dependent on x86, hence you need to use the old FFI syntax to have it working on the raspberry pie (there is some code to load in the image to do so).
