PicoScope crashes at startup in Ubuntu 16.04 LTS

Postby emalian » Mon Aug 29, 2016 7:07 am

Hi,
I probably posted this in the wrong forum before (writing your own SW, Linux) so reposting here.

Received my brand new PicoScope 3406D MSO today, and thought I'd give it a go. I quickly ran into trouble, though. The PicoScope Linux SW crashes at startup if my picoscope is connected to my computer. If I start the SW without the scope connected, it starts up fine. If I then connect the scope and do File->Connect device, the SW crashes. Dmesg really did not give much clue as to what goes wrong. But adding some dmesg output anyway below. I'm running Ubuntu 16.04 LTS, updated as of today, on a standard desktop computer (~5 years old). Any clues as to what is wrong?
BR,

Malin

Hi Malin,

Would it be possible to post the trace.xml file from the last time the software crashed - it is located here:

Code: Select all
~/.local/share/Pico\ Technology/260a68f1-30f-0a5e01d65514

Alternatively, you can e-mail it to support@picotech.com

Edit: The trace file should show this but it would be helpful to know if you are using a USB 2.0 or USB 3.0 cable/port combination and if the power supply is being used.

Thanks,
Hitesh
