My Df is broken, it doesn't recognise the memory cards anymore.
It looks like something is stuck inside.
Bummer Chris, do you think you can fix it yourself?
I'm afraid not. Tried to blow it out, but it seems some pins are out of alignment or so.
A trip to NSP when I get home.
Hope you get it back quickly.
Chris,
The SD card mates with spring loaded raised metal bars inside the carrier. If you look at your SD card you can see where those V-shaped bent metal tracks will have rubbed against the copper areas on the card. Unevenness on those markings might give a clue. It is possible that one of those raised tracks inside the DF's card slot now doesn't make contact with the SD card - or has somehow been jammed under the surrounding plastic guides. Another problem might be a dry joint from the DF's card reader pins to the little PCB that is sits on. Worst case is that there is a problem with the SD data getting being sent from the Expeed processor.
I have had problems with cheap external SD card readers where wear and tear have compromised the pressure of the contact point.
Here are some pictures from an exploded view of an SD reader an the spring loaded contacts. Note that this a fix for a Raspberry Pi housing issue - however the the pictures were quite clear hence my reference.
If you look into your SD slot on your DF can you see the 9 raised pins?
Silly question but presumably you have tried another card to make sure that there isn't anything wrong with the 'lock' function since there is a 10th pin orthogonal to the others.
