For the very first time an error dialog box appeared yesterday. The
formatting looked more like a Windows widget, so I think it
probably came from the application, not the system. It reported an
"incompatible magic value nnn...nnn in class file java/util/....".
That suggests whatever is going wrong has nothing to do with RasPiOS,
so maybe I shouldn`t expect anything to show up in system error logs.
There`s been an ongoing compatibility problem with the application.
When I set up the Pi2 and tried to use the oscilloscop it worked
perfectly. After the first RasPiOS update, it stopped working. Moving
to a Pi5 with a more up-to-date RasPiOS, it never worked. The application
always ran without error but could never connect to the `scope, even
though lsusb reported the `scope was connected.
On the Pi2 I started with, it gradually emerged that shortly after
boot, the program and `scope worked fine, but after a few days` uptime
the whole system became unstable. It looked like the window manager
would crash, leaving a black screen, no mouse pointer and sometimes
an unresponsive capslock key. Power cycle was the only way out. This
behavior seems independent of whether the `scope software is in use.
The oscilloscop and software seem to work well when they work so it`s
a bit frustrating. For the time being, I`m baffled.
Thanks for writing!
