<font size="+1"><font face="monospace">Hi guys,<br>
<br>
today i made several test with Cuis5.0-4834-32.image and the
latest release of the VM<br>
in the BeagleBone Black. <br>
<br>
Here is what i found:<br>
<br>
* The latest stable release of the VM is broken:
squeak.cog.spur_linux32ARMv6_202003021730.tar.gz<br>
I put the error message at the end.<br>
<br>
* Then, I used the latest build. That runs. <br>
<br>
* It is possible to work in Cuis, there is an improvement. I
used only this ligthenings:<br>

it goes all fine.<br>

* The system is always at load average higher than 0.90. Part of
it is VNC, part of it is CUIS.<br>
So, it can be used for entertainment but for work objectives
still better to use a larger computer.<br>
I wish to tray the BeagleBone AI as soon as I can. <br>
