Error: IsMV Failed

Post by b2ag » Thu Mar 03, 2016 8:09 pm

Hi,

I've trouble getting Picoscope to work under Arch Linux.

Usbtest-Tool says everything is fine. PS6000con works fine. Picoscope-Application complains about "Error: IsMV Failed".

Could not paste full logs, because Apache Mod-Security, I guess.

Bye

I've got the same error message on ubuntu 14 with the latest version of picoscope.
usbtest and ps3000acon both work but picoscope doesn't ever detect.

Actually the error is most commonly associated with mono version. Versions 4.2.1 and newer carry piece of the code that breaks Picoscope 6 for Linux. The fix has been supplied to Mac version, Linux version will get it in the next release. In the meantime I can only advise to use older versions of mono, like 3.2.8.

Thanks Mario and Martyn.
Is there any info on running an older version of mono on an ubuntu system? I don't think I can downgrade it easily (too many dependencies) so I'd need to install it somewhere else.

https://software.opensuse.org/download/ ... e=mono-opt

Unfotunately only version for ubuntu12 is 4.0.4, free from this bug. The others are up to date. You could trying using ubuntu12 setup, even if you have different version of this os.

There is alternative with mono 3.12: https://software.opensuse.org/download. ... e=mono-opt
This one does not provide gtksharp-2 and mono-basic. Would require more fiddle.

Picoscope6 package requires normal mono to be installed. Mono-opt is not replacement, so the the startup script will need changing.

Before the lines of (around line 20):

Code: Select all

CLI_CMD=$(which cli 2>/dev/null)
MONO_CMD=$(which mono 2>/dev/null)
Add suited to your installation entries, to look like (in case of mono-opt):

Code: Select all

export PATH="/opt/mono/bin:$PATH"
export LD_LIBRARY_PATH="/opt/mono/lib:$LD_LIBRARY_PATH"
CLI_CMD=$(which cli 2>/dev/null)
MONO_CMD=$(which mono 2>/dev/null)
You can try and compile you own version of mono, but it may create greater sea of problems. If you still think of doing it prepare your system to have all bits required for it:

Code: Select all

 sudo apt-get build-dep mono-runtime mono-basic gtk-sharp2
Download yourself a sources of mono, mono-basic and gtk-sharp2. They may require associated patches to compile at all - check the folders they are coming from. After extracting, first run ./configure --prefix=/path/to/where/it/goes for mono, then make and sudo make install. Next one is mono-basic: again ./configure --prefix=/path/as/before , then make and sudo make install. Finally gtk sharp, ./configure --prefix=/path/as/before RUNTIME=/path/as/before CSC=/path/as/before/bin/mcs PKG_CONFIG_PATH=/path/as/before/lib/pkgconfig , then make and sudo make install.

Or... just wait for the next picoscope release.

Hi, I am experiencing the same problem on Arch Linux, and I would prefer not to downgrade the Mono package, because of other software I have that depends on it.

When will the fix be available to the Linux version of PicoScope?

Thanks!

Hey Martyn -

Thanks for the update. Do we know what version of picoscope will have this bugfix? I'm currently seeing the error in my 6.11.8.10 install.

I had the same problem on Ubuntu 16.04, and confirm that the 6.11.8.13 version works correctly.
My mono version is Mono JIT compiler version 4.2.1 (Debian 4.2.1.102+dfsg2-7ubuntu4).
Thank you for the support.
