This app note (2148) below shows how to use the SPI bus/mode to talk 
to an SDIO card. I have cut and paste the example and it compiles 
correctly, but when I run the program, it behaves the same, regardless 
whether or not there is an SD card in. 

The result is, it gets stuck waiting for a response that never comes, 
and goes into its infinite while(1). 

Has anyone got this to work? Can anyone post some code that works? 

Thanks, 
AH
