Dear greg,

Thank's again for your reply.
I sent the file already by email, but I am not sure whether you received it. So here the content of trace.xml again.

Kind regards,
lohan

I just installed the new version, but it still crashes due to that mono error. :cry:

Hi lohan,

Thanks for the trace file. Please try updating to the new release.

Do you have this problem when running PicoScope without the device attached?

It may also be worth reinstalling the mono packages. The problem seems to be in libgdiplus.so

I installed the newest mono 3.10.0 and the new version of picoscope software. It still crashes, also when I plug on the device after having started picoscope software.

picoscope crashing here as well under opensuse 12.3/64bit and on 13.1/32bit.

would have to nice if it was running under linux :(

is this still under investigation or "is the file closed"?

Still crashing. i can open picscope and connect to the demo device. When i plug the device in and select it the app closes.
Attached is the trace file and this is the output of the app after crashing

Re: Beta Release of PicoScope for Linux

Postby Lotharyx » Sat Dec 06, 2014 4:14 am

Looks like this is a very active and recent topic. I just installed the PS6 Beta on Debian 7.6 (Wheezy) x64, and get the same crash. Attached a text file capturing the console output. I sure hope this gets fixed! I can use Windows, but it would be tremendously convenient to be able to use Linux, as that's where I prefer to do other development related to the project I'm using the Pico 'scope on.

I can get the GUI to appear fully if I start with the scope unplugged. The crash occurs shortly after enumeration after I plug the scope in. It also crashes if I start the application with the scope already connected.

Re: Beta Release of PicoScope for Linux

Postby mario_ » Mon Dec 08, 2014 4:29 pm

Hi All,

I have been trying to replicate the issue on many of our lab, test, dev PC & VMs (including few private ones). So far no crash was observed. But we're getting more and more reports from several customers about that. There must be some sort of a common ground on which the application crashes.

From the reports we have received the problem is not with permissions - as it also crashes when it is run via sudo. But Those who didn't tied yet, could do it please?
Code: Select all
sudo /bin/bash -c "cd /opt/picoscope/lib/ && mono PicoScope.GTK.exe"


Some of you provided full stacktrace of the crash - many thanks, very helpful. The listings show that crash occurs within libusb code (on which PicoScope 6 drivers for Linux strongly rely on). I have tested various version of libusb - but not all. Can you provide which version is actually used on your system?

For Debian/Ubuntu/Mint:
Code: Select all
dpkg -l | grep libusb


For SuSe/Fedora:
Code: Select all
rpm -qa | grep libusb


I look forward into receiving further reports from you. I will keep the investigation going.

Many Thanks,
Mario

crashing with opensuse 13.1/32bit:
libusbdrdaq-1.0.4-1r09.i386
libusb-1_0-0-1.0.9-8.1.2.i586
libusbredirparser1-0.6-4.1.2.i586
libusb-0_1-4-0.1.13-27.1.2.i586
libusbredirhost1-0.6-4.1.2.i586
libusbmuxd2-1.0.8-8.1.2.i586

crashing with opensuse 12.3/64bit:
libusb-1_0-0-1.0.9-5.1.1.x86_64
libusbmuxd2-1.0.8-5.5.1.x86_64
libusb-0_1-4-0.1.13-23.1.1.x86_64
libusbredirhost1-0.6-2.1.1.x86_64
libusbdrdaq-1.0.4-1r09.x86_64
libusbredirparser1-0.6-2.1.1.x86_64

crashing as well when run as root.
crashing as well when starting demo mode

on opensuse 12.3 I am able to run picoscope within windows XP which is running in a VM - but that's not really convenient.

Hi pipau,

Thanks for the list of version. I have brought my installation of suse12 to your versions and the crash happens. There is workaround for this:
  • Start PicoScope6 without any device plugged in.
  • Choose not to start Demo Device.
  • Plugin your scope.
  • Use File/Open Device to get it running.

not working here for both versions of OS -> crashing after a device is selected
with 13.1 the device can not even be selected, onl demo (Although I can hear the relais clicking before)
