Hi, Here is another step forward in getting Pharo 3.0 to run on a Raspberry Pi. Yes: pi@raspberrypi ~/Pharo-3.0 $ ../PharoRPi/PharoS -vm-display-null -vm-sound-null Pharo.image eval 'SystemVersion current' Pharo3.0 of 18 March 2013 update 30710 pi@raspberrypi ~/Pharo-3.0 $ ../PharoRPi/PharoS -vm-display-null -vm-sound-null Pharo.image eval 'ZTimestamp now' 2014-01-20T18:21:50Z No errors. No: When doing something more complex, like: pi@raspberrypi ~/Pharo-3.0 $ ../PharoRPi/PharoS -vm-display-null -vm-sound-null Pharo.image eval --no-quit 'ZnServer startDefaultOn: 1701' a ZnManagingMultiThreadedServer(running 1701) The HTTP Server does respond normally to one request and then seems to hang. When running with a UI, the image comes up, draws everything but remains unresponsive otherwise. No PharoDebug.log output. Events ? Multi-processing ? How ? Use Jean-Baptiste's VM from here: https://ci.inria.fr/pharo-contribution/view/RaspberryPi/job/RaspberryPi-Comp... Take a stock 3.0 image and apply Pavel's unloadNB.st script (see the thread with subject unload all). So, we're getting closer... If anyone is interested, I could make some kind of all in one download. Sven
