[USRP-users] Enable AGC in USRP E320 with RFNoC using GNURadio

Hi all, I was wondering if it is possible to enable AGC from the RFNoC radio block in GNURadio. I use UHD 4.0 version and GNURadio 3.8 with gr-ettus. I see that the RFNoC Rx radio block has an enable/disable/default AGC option in the GNURadio block which I assume calls the UHD function

[USRP-users] Generate blocks with more than 1 input/output using rfnocmodtool

Hi all, Is it possible to automatically create an rfnoc_block schema with, for example, 2 inputs and 2 outputs payload stream packets as in the addsub blockdata using rfnocmodtool? I can generate it using rfnoc_create_verilog.py through a block.yml file following the steps in :

[USRP-users] FPGA RFNoC Radio block with only one channel

Hi everyone, I'm using an USRP E320 using the RFNoC image to implement a code that requires too much FPGA resources. I only need to use one of the channels of the USRP so I was wondering if it could be possible to eliminate the logic associated with the other channel to save resources on the FPGA
