Hi all, with the last version of volumio on raspberry pi 0 i have seen this problem.
after flash the rom i started it into the pi and after some times i can found it under my net, but i can start the web ui interfaces. (i use usb adapter for the net).
if you leave the card and check it with gparted on linux you can found that there is a problem with the last partition of the card. if you fix it the volumio star correctly. I had tried 3 sd different card some problem, i suggest to check it if someone can’t start Volumio.
