MicroSD support on EMX


#1

For a new project based on EMX cobra-like i have to use a microSD for space reason.
Is four line communication bus size of microSD supported automatically by your firmware after power up ?


#2

SD or Micro SD they are the exact same thing internally.


#3

Thanks , this means that bus size command communication (4 bit) is automatically set at power up ?


#4

Sorry. Possibly wrong answer. Don’t have a Cobra.

If you take a look at the Cobra, which uses an EMX module, the SD card socket has no other connections that would change the behaviour. The standard connection GHI use is the 4-data-bit connections so I can’t see why there would be any question about this.

Yes 4-bit on all FEZ boards :slight_smile: Another GHI exclusive feature!
