Hello, 
i have just assembled my first LPC core and i will use the MIDIBOX NG firmware. 
i have also made the sd card adaptor as in the schematics.For a memory card i use a 4 gb micro sd. 
  
When i open the core i get the message that there is NO sd card pluged. 
  
when i write on the terminal the command "sdcard" i get this :    attached file at the bottom "reply.jpg" 
  
  
I have checked 4 times all the connections from j16 to sd card adaptor and from the j16 to the pins of the LPC. 
I have also checked the presence of 3,3 volt and all seem perfect! 
  
I can't find what am i do wrong. I am waitting for suggestions in order to continue my project. 
thanks in advance
