Hello experts;
I want to read an SPI signal coming from external source into my system via USRP FPGA. I am using this command;

read_write_spi 
          (
          unit_t 
          unit, 
        
        
          

          

          const spi_config_t & 
          config, 
        
        
          

          

          boost::uint32_t 
          data, 
        
        
          

          

          size_t 
          num_bits 
        
        
          

          )
          
my question is;
from which pins (on the USRP) shall i suppose to read the SPI values ? are these pins the same as GPIO's ? or they are differently mapped on USRP board ?
