[Discuss-gnuradio] 4rx FPGA image issue

[Nada ABDELKADER]

Hi all,

I'm using two USRP1 as transmitter and receiver.
I'm trying to make the receiver listening to three channels. I found  
that I have to use the 4rx FPGA image for 4 RX DSPs on the USRP1.
But when I run my command with  the <<  
--args="fpga=usrp1_fpga_4rx.rbf" >> option and I got this error:

thread[thread-per-block[0]: <gr_block gr uhd usrp source (6)>]:  
LookupError: KeyError: Cannot find a conversion routine for conversion  
ID
  Input format: sc16_item16_usrp1
  Num inputs: 1
  Output format: fc32
  Num outputs: 3

I did not understand the origin of the problem and how to resolve it.
Can anybody help me plz?

Regards,
Nada
