RE: [beagleboard] mmcinit --> No MMC card found

Sounds like one of:

  1. the SD card isn’t formatted correctly, see here: http://code.google.com/p/beagleboard/wiki/LinuxBootDiskFormat)
  2. the card is in upside down (the SD connectors on the back of the card should point down towards the PCB)
  3. the socket is damaged, most likely one of the pins connecting to the PCB has come loose.
