Waveforms Illegal Instruction on Raspberry Pi Zero

[talon]

Hello all,

I'm trying to run an Analog Discovery 2 off a Raspberry Pi Zero W for long duration data recording. I'm running into an issue with getting Waveforms to start on the Pi. When I start it from the command line I get "Illegal Instruction" and nothing else. I think it has something to do with the libdwf.so because i was seeing the same error with a Python script. I don't get an error with 

ldd libdwf.so

but I do get the same illegal instruction error with

python3 -c "from ctypes import *; dwf = cdll.LoadLibrary('libdwf.so')"

Installed SW:

• digilent.adept.runtime_2.26.1-armhf.deb
• digilent.waveforms_3.17.1_armhf.deb
• Also tried with digilent.waveforms_3.18.1-armhf.deb
• Raspberrypios 5.10.103+

I have run apt update, upgrade, -f install, --fix-broken.

Any other suggestions on what I could try would be appreciated!

Hi @talon

The armhf packages for adept and waveforms are built for armv7. What is your system architecture ? see it with: $ uname -a

You could try the dwfcmd which is installed by waveforms, like:
$ dwfcmd enum

Hello @talon

If you have WaveForms application installed and working try the following: Open a terminal and enter the command (cd ../../usr/share/applications/ && waveforms /home/pi/default.dwf3work). 

The parentheses (...) instructs Linux to run two commands on a single line and default.dwf3work is your setup file. 

If this works, you could put the command in a .sh file and make it executable with the chmod +x filename

if this is not what you are after, ignore me and listen to Attila :-)

Best regards,

John

Hi @attila and @JRys

Unfortunately I don't have WaveForms working, but the suggestion is appreciated!

My system architecture is armv6l

Linux raspberrypi 5.10.103+ #1529 Tue Mar 8 12:19:18 GMT 2022 armv6l GNU/Linux

Do any older versions of WaveForms and Adept support armv6l?

Thanks!

Hi @talon

The last armv6 binaries are the following:

Hi! I've just installed the adept runtime and waveforms from the links provided by attila, when i launch waveforms, a window momentarily appears, then closes, has anyone been able to run waveforms on the pi zero w? Thank you
