What problem you encounter ? writing problem ? booting problem ?
Which system do you use to write your Sd card ?
for instance on a linux computer, do a df in console, insert your card and redo df. Note the name (/dev/sdcx)
In in the folder where is the Volumio img type
sudo dd if=volumio1.55.img of=/dev/sdc
CAREFUL remplace sdc by YOUR sd card name because everthing on the designed device will be erased!
When finished, insert in your PI and power it. You’ll see blinking led. After about 60sec a welcome sound… and from a other device try to connect to
http://volumio.local or to IP adress from a android smartphone.
Hope it will help…
