Hello,
Is it possible to share a SD minimap between two Arduino?
Thank you.

So I guess the question is really "can the Arduino support multi-master SPI bus"?

To which I think the ATmel datasheet says "yes", but with caveats.  Certainly you'd need
to look carefully at the SPI section of the datasheet.  Some arbitration outside the
SPI bus seems wise
