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

[Bruce O'Neel]

Hi,

Yes the Armv6 VM from 202003 is bad.  That's the bad news.

The much much better news is that we (well others, not me) have
stamped out many bugs and the ArmV6 VM works well now.

You can download a somewhat recent version that built from here.

https://github.com/OpenSmalltalk/opensmalltalk-vm/releases/tag/latest-build

You can also download the source and build.  It takes a few minutes
on a Pi 3. 

cheers

bruce
