Picoscope 2205A and Manjaro Linux in 2024?

nicknack2020 · Post by **nicknack2020** » Mon Mar 18, 2024 11:21 am

Hi

I am attempting to use my 2205A with Manjaro linux. From the AUR I installed "Picoscope 7 Test and Measurement stable"

Ran it with my Picoscope 2205A. In the "Devices" window it shows the detected Picoscope, but it is greyed out and says "Not supported"

I removed Picoscope 7 and tried to install Picoscope 6.14.36_4r5676-1

It would not commit the transaction, it gave these errors:

conflicting files:
- libpicoipp: /etc/ld.so.conf.d/picoscope.conf already exists in filesystem (owned by ps7_libpicoipp)
- libpicoipp: /opt/picoscope/lib/libiomp5.so already exists in filesystem (owned by ps7_libpicoipp)
- libpicoipp: /opt/picoscope/lib/libpicoipp.so already exists in filesystem (owned by ps7_libpicoipp)

I manually deleted those files and tried to comit again. Similar errors with other files. I deleted them and eventually it built Picoscope 6 no problem.

When I ran it, it does not detect my Picoscope. Yel lsusb shows it is connected:

Bus 001 Device 021: ID 0ce9:1007 Pico Technology PicoScope 2000 series PC Oscilloscope

Has anyone successfully installed any flavour of Picoscope on a Manjaro Linux system?

Thanks

That is the message you get when using the PicoScope 7 Automotive Software with a PicoScope 2205A.
Can you post a screenshot showing this.

Sure!

FYI the AUR package I built is shown in attachment 1.jpg

The Picoscope application itself has in the title bar: "Picoscope 7 T&M"...

Attachment 2.jpg is a screenshot of the error message

Thanks

Hi Nick,
Check the USB device Permissions-
Open a terminal-
Connect the PicoScope to a USB port on the PC.
Issue the command

Code: Select all

lsusb –l

Does this command list Pico device(s) connected?
check USB device Permissions-

Code: Select all

cat /etc/udev/rules.d/95-pico.rules

Should give-

Code: Select all

ATTRS{idVendor}=="0ce9", MODE="777"

You can change the permissions if they are not correct with-

Code: Select all

sudo bash -c 'echo "ATTRS{idVendor}==\"0ce9\", MODE=\"777\"" > /etc/udev/rules.d/95-pico.rules'

I will try a PicoScope with my Laptop tomorrow.

Thanks for the swift reply Andrew.

Unfortunately, the commands and file paths you give are not present on my Manjaro system.

For example, "lsusb -l" results in:

"lsusb: invalid option -- 'l'"

On my manjaro system, the valid switches for lsusb are v, s, d, D, t, V, h

Using simply "lsusb" lists all the usb devices, and among the is the Picoscope:

"Bus 001 Device 004: ID 0ce9:1007 Pico Technology PicoScope 2000 series PC Oscilloscope"

But trying to add a udev rule for the picoscope fails:

"cat /etc/udev/rules.d/95-pico.rules" gives: "no such file or directory"

According to the ArchWiki for udev rules, "The udev rules shipped with various packages are found in /usr/lib/udev/rules.d/"

But in this folder is nothing from Pico technology...

However for administrator added rules: "udev rules written by the administrator go in /etc/udev/rules.d/"

So I modified your suggested command thus

Code: Select all

sudo bash -c 'echo "ATTRS{idVendor}==\"0ce9\", MODE=\"777\"" > /etc/udev/rules.d/100-pico.rules'

I rebooted. No different...

I have hit a wall here. I will await your experiment with your own Manjaro system...

Thanks

P.S. For those going doen this particular tunnel, the ArchWiki on udev rules is here:

Hi,
Ok I had little look at this, and this what I found-
Fist tested by installing Picolog 6 which is a Appimage. This worked and could connect to the scope! Good!
Back to PicoScope 7-
The open Picoscope 7 device box seems to detect my 3206D as a "3000A series"? but fails to connect.
Going to terminal and issuing "lsusb"
Its listed it as-
"Pico Technology.....Westbridge"
Westbridge means the PicoScope's firmware has not been loaded and the USB connection has not been reconnected.
Looking in "opt/picoscope/lib/"
This has missing shared library files!
I tried copying the missing files from my Ubuntu box, and fixing the missing symbolic links, but I could get the PicoScope to connect.

I would try and install the Debian package need for your PicoScope(s), have look at-
https://forum.manjaro.org/t/how-to-install-deb/34452
And try using the "debtap" tool.
Picoscope 2205A uses the libps2000.so library file.
So try installing the current libps2000*amd64.deb package from -
https://labs.picotech.com/rc/picoscope7 ... libps2000/

Unfortunately we don't officially support manjaro or Arch linux.
Maybe someone can get this to work.

I've installed today PicoScope 7 on Arch Linux and it just worked.
picoscope7 7.1.21_1r18179-1
I had to install ps7_libps2000 (3.0.130_3r5654-1) instead of ps7_libps2000a to make it see my PicoScope 2205A .
