NRF24L01 not working, printDetails gives zeroes, schematics provided!

So I've been trying to build a transmitter, and I've designed it in Eagle and ordered the PCBs. Everything should work just fine, but sadly it doesn't.. printDetails gives me the following:

Does anyone have a clue?

The code I'm using can be found below:

/*
http://arduino-info.wikispaces.com/Nrf24L01-2.4GHz-HowTo
1 - GND
2 - VCC 3.3V !!! NOT 5V
3 - CE to Arduino pin 9
4 - CSN to Arduino pin 10
5 - SCK to Arduino pin 13
6 - MOSI to Arduino pin 11
7 - MISO to Arduino pin 12
8 - UNUSED*/

  // optionally, increase the delay between retries & # of retries
  radio.setRetries(15,15);

  // optionally, reduce the payload size.  seems to
  // improve reliability
  radio.setPayloadSize(8);
  DEBUG_PRINTLN( "Payload Size" );

  radio.openWritingPipe( RADIO_PIPE );
  DEBUG_PRINTLN( "Writing Pipe" );


  radio.powerUp( );
  radio.startListening( );

  radio.printDetails( );
  DEBUG_PRINTLN( "Details" );
}

I've attached both the Eagle schematic and Eagle board file.

Bump, I'm pretty desperate :frowning:

Which Arduino are you Using?

It looks to me that you are not getting communication with the nRF24l01. Shouldn't the:

 radio.openWritingPipe( RADIO_PIPE );

showup as changes in the

  radio.printDetails( );

Chuck?
