I'm able to boot up Volumio on my 3B+ pi. When I try to boot up RuneAudio_rpi2_rpi3_0.4-bets_20160321_2GB, it just stays at single red led and shows no sign of booting up even after 6 minutes. I'm able to boot up Ropiee but its Rune I want to get working. The micro Sd card is formatted for Fat32. Any ideas why it's not booting. I went through the trouble shooting tips check list on Rune.
