Yes, I’ve followed the installing instructions but:
- on laptop PC noway to have the USB passed to the VM; anyway the localhost:8888 on host PC chrome works and allow me to get into Jupyter (but no chipwhisperer connected ).
- on desktop PC: USB is working fine but noway to have the host Chrome connected to VM with localhost:8888. This is the reason why I’ve installed here the gnome and so on.
Later on i will try to disconnect the DeskTop PC from LAN network to see if it will works an will let you know.
Trying Python in debug I saw that the problem seems to be in the answer from the target.
If you are interested in these details I can send you some screenshot later today.
Thank you and best regards.
PS: I saw in some old posts (on github) someone had a similar problem and the suggestion was to verify the voltage level on some pins because of possible voltage missmatch. Do you think it could be also my case or it was an old issue already fixed?
Fisrt test: I succeed in having the original VM working in VirtualBox as expected and with the USB enabled.
So tested as suggested with the same result:
