EOS C300 Won't Recognize 32GB SD Card

[RNWalkabout]

We have an older C300 w/o pixel upgrade running firmware 1.1.3.  Want to upgrade but camera will not recognize a 32 MB sdhc SD card.  Displays error "check sd card".  Any thoughts?

What specific brand of card are you using? Also, is it full-sized or micro?

Did you attempt to format the card in the C300?

Sorry for the typo.  It is actually a 32GB Sandisk.  But the issue turned out to be a loose ribbon connector to the board that holds sd card reader.  I re-seated that and camera now works fine.  Thanks for the timely response.

Hi, RNWalkabout!  Are you sure it's a 32MB card?  We ask because that's a really, really small capacity and Cinema EOS cameras generally require far larger capacity like what you'd find on a 32GB card.  Please verify this so that the community can get the clearest possible picture of what's going on.
