BCON Camera (dart) - example

[L-o-r-e-n-z]

I try to communicate with the pypylon on an iMX8 with a camera with BCON connection. Unfortunately all the samples do not work and create an exception:

root@imx8mmevk-basler:~/camera# python3 grabone.py
Traceback (most recent call last):
  File "grabone.py", line 6, in <module>
    pylon.TlFactory.GetInstance().CreateFirstDevice())
  File "/usr/lib/python3.5/site-packages/pypylon/pylon.py", line 1755, in CreateFirstDevice
    return _pylon.TlFactory_CreateFirstDevice(self, *args)
_genicam.RuntimeException: No device is available or no device contains the provided device info properties. : RuntimeException thrown (file 'TlFactory.cpp', line 692)
root@imx8mmevk-basler:~/camera#

When I start the pylon Viewer I see the camera and I can capture images... What do I do wrong?

I made one step forward, now I get a different error message, but still no image can be received:

Please use the sample code from the project readme as first start. The error message gives you the hint what is not working.

Grabone.py is using chunks, that are not yet available on a BCON for Mipi Interface

thank you very much, now I get some image data:
