So I’ve tried another micro SDHC card. A smaller card. 8 GB.
That worked so I guess that the 64 GB card that I have is not supported by RPI.
So I’ve proven that I can get a micro SDHC to work with retropie I just need a supported card. I’ll have a look at http://elinux.org/RPi_SD_cards and buy one that is marked as OK in this list.
