There is similar type thread here:

...and based on that and my own device I would say that it's not the card. Both the internal and external mmc's simply vanished as far as the OS is concerned. For example neither shows up in filemanager or control panel.

I have flashed the device with no help.
I have the OS running from original flash and not sd card.

Any suggestions anyone?
