[Cuis-dev] New tests in ARM 32bit with BeagleBone Black

[Nicola Mingotti]

Hi Bruce,

yes, i saw the latest build does work.

It is unfortunate that the lastest "stable" is broken.
Maybe it would be better just to delete it.

I am going to try a build the VM sooner or later, still there are many 
things i need to understand
well about Smalltalk before switching the focus into the underlying engine.


bye
Nicola
