[ADP3450] Test-Scripts from 'WaveForms-SDK-Getting-Started-PY' not running with Waveforms 3.18.19

[AnSp]

Hej Discovery-Users,

During my first tests in Linux mode with the ADP3450 I received the following error message, when trying out 'test_scope-wavegen.py' from 'WaveForms-SDK-Getting-Started-PY' (Commit #009b7cc):

digilent@ADPro:~/test/WaveForms-SDK-Getting-Started-PY$ python3 test_scope-wavegen.py
Traceback (most recent call last):
  File "test_scope-wavegen.py", line 53, in <module>
    spectrum = tools.spectrum(buffer, tools.window.flat_top, scope.data.sampling_frequency, start_frequency, stop_frequency)
  File "/home/digilent/test/WaveForms-SDK-Getting-Started-PY/WF_SDK/tools.py", line 55, in spectrum
    dwf.FDwfSpectrumWindow(window_buffer, ctypes.c_int(buffer_length), window, ctypes.c_double(1), ctypes.c_double(0))
  File "/usr/lib/python3.7/ctypes/__init__.py", line 369, in __getattr__
    func = self.__getitem__(name)
  File "/usr/lib/python3.7/ctypes/__init__.py", line 374, in __getitem__
    func = self._FuncPtr((name_or_ordinal, self))
AttributeError: /lib/libdwf.so: undefined symbol: FDwfSpectrumWindow

I guess the function FDwfSpectrumWindow is linked in newer releases of Waveforms.

AttributeError: /lib/libdwf.so: undefined symbol: FDwfSpectrumWindow

On the ADP3450 I installed the latest Waveforms revision 3.18.19 for armhf from 2022/2/23.

Is there a newer version/release fpr armhf available (3.18.59 only for x86?) or is there another solution to update the libdwf.so?

Thanks for your advice in advance,
Andreas

Hi @AnSp

You have in private message the software version for ADP3X50 and armhf which supports these newly added functions.

Hi attila,

after installing the new adept runtime (2.27.6) and running 'test_scope-wavegen.py' I received a new error message:

digilent@ADPro:~/test/WaveForms-SDK-Getting-Started-PY$ python3 test_scope-wavegen.py Bus error

What does "Bus error" mean?

When running another test script (e.g. test_device_info.py) there ist no output to the bash.

Is there another software module that has to be updated before using the SDK examples in linux mode?

Thanks in advance,
Andreas

Hi @AnSp

I'm not familiar with this code but the included examples seem to work. I suppose it is some problem in getting started.
