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
