Its bricked the card again, running good but vna was not installed yet so 
I have it in a reader here getting ready to dd the beta image again. 
Then I am going to reboot it every step of the way as I try to complete 
the install to find what/where its getting bricked. The /root directory 
is empty, so is a /home/izi, but /home/redpitaya has nothing.
ls -l ing around I find:

ls -l /media/usb0/home/jupyter/RedPitaya/

-rw-r--r-- 1 root root 2682 Sep  1  2017 welcome.ipynb

Which looks maybe like where I'd put vna.py and vna.ui. Maybe, doing an 
ls -lR, it finds:

which looks  like where those files should go since they are drivers, but 
I don't see any other .ui things anyplace, _But_ theres a boatload of 
pip3 and pip installed matplotlib & related stuff the rest of it doesn't 
need just in front of the vna install too.

Anyway, start with a fresh .img file. It will boot, and network manager 
will set a static address. Reboot to see if it will, then theres a ssh 
root at address. reboot. then do an apt-get update. reboot. Then apt-get 
about a dozen bits of python3. reboot. pip3 install some more python 
starting with matplotlib. reboot. We'll see where the reboot fails.  

Hell of a way to run a train. 

Cheers, Gene Heskett
