Re: Pico 7 for Linux

So no hoard of zombies thankfully but on driver install it said "same version already installed" then trying to open the 6 file I got "file load integrity check failed" (with 4425A plugged in)
TBH I can get around it by loading 6 files in Win 10/Pico 7 on my diag laptop then sharing them with the Linux machine.
How soon after the Windows version does the Linux version update and what's the best way to keep it updated ?
Had some issues but no point in reporting if already fixed on Win release - Though I had a big one today trying to apply a maths channel to a reference waveform - locked up my PC to needing a hard re-boot that I have not needed to do in a year!

Typically we release builds for all 3 platforms simultaneously. Linux builds were delayed recently due to an issue on our internal servers which has now been rectified.

Additionally all versions should be released at the same time (when applicable). Stable Automotive (and we dont yet mark any T&M stables) will be less frequent but T&M and Automotive early access versions should go live at the same time, give or take 5 minutes. We aim to release Early Access builds once every 2 weeks. Stable builds are cherry picked on a less frequent basis.

Easiest way to remain up to date on linux is simply as part of your usual apt update && apt upgrade regime. You will automatically get the latest build for the relevant repository. Reminder:

Code: Select all

https://labs.picotech.com/rc/picoscope7/debian/
https://labs.picotech.com/picoscope7auto/debian/
https://labs.picotech.com/rc/picoscope7auto/debian/
In order these are the repositories for T&M Early Access, Automotive Stable, Automotive Early Access and you can edit your /etc/apt/sources.list.d/picoscope7.list according to which release stream you'd prefer.

The lockup issue, we are actively investigating and attempting to fix. You can recover the PC by killing the task from taskmanager, or using pkill on linux/mac.

Thanks, good to know about the updates. I'll leave it on the automotive stable - I can wait for the driver issue to be hopefully rectified and use the work around I mentioned.

Just installed the latest EA update and the desktop is going into full fan mode- nothing else running :

Not had any resource issues before

Tried to install stable but the repository given appears to be the same for the EA and I get "already installed"

Hello and thank you for the post

This is interesting indeed re CPU usage and something that has been raised with the software engineers on other platforms

Rest assured this will be investigated and any amendments shared accordingly.

Re the CPU 1 usage at 100% was this purely PicoScope in Demo mode or were any other applications running simultaneously?

The image suggests 100 % for approx. 10 seconds then reverting to similar values for CPU 2, 3, & 4

Could you indicate the full PS7 build/version number where you first noticed this issue and I will add this to a software report?

Take care.....Steve

Hi
PicoScope PicoScope 7 Automotive Early Access - PC Oscilloscope software
version: 7.0.81.91627
Just pico in Demo as I had just re-booted the PC as the P7 update had not loaded into the menu, then I started system monitor when it started to ramp up the CPUs.

Any news on the Stable version for Ubuntu 20.4 ? the Download page still shows same repositories for both.

Early access:
sudo bash -c 'echo "deb https://labs.picotech.com/rc/picoscope7auto/debian/ picoscope main" >/etc/apt/sources.list.d/picoscope7.list'

Stable
sudo bash -c 'echo "deb https://labs.picotech.com/picoscope7auto/debian/ picoscope main" >/etc/apt/sources.list.d/picoscope7.list'
