Read CID from SD Card

Postby skaman » Wed Dec 15, 2010 10:46 pm

Would it be possible to read the Card Identification Register (CID) for the SD Card and display it?

If the CID can be read, then the CSD should also be accessible.

Details on accessing the CID and CSD registers are here: http://china.maxim-ic.com/app-notes/index.mvp/id/4068

Thanks!

Being able to read the CID and CSD could help internally identify the qualities of the attached SD card.

Manufacturer ID, Product Name, Product Revision, Serial #, CRC, Transfer Speed, Sector Size, etc.

It could help identify SD card problems - slow cards, fake cards, mislabled cards, corrupt cards, etc.
