When I used this doc <https://kb.ettus.com/Getting_Started_with_RFNoC_in_UHD_4.0> and add the FFT block to the USRP x300 block not work correctly and send the command OOOOOO... For another original block, I had the same problem...How can solve my problem? Errors: gr::log :DEBUG: rfnoc_rx_streamer0 - Committing graph... [WARNING] [0/Radio#0] Attempting to set tick rate to 0. Skipping. gr::log :DEBUG: rfnoc_rx_streamer0 - Sending start stream command... OOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO [image: Screenshot from 2022-05-25 10-01-56.png]

I closed this thread. Finally my problem is solved by adding spp parameter in RFNOC Radio core blocks. more info see this link https://lists.ettus.com/empathy/thread/VJB7A53C6X77JN7DPP3ATASYO4MAH7GH On Wed, May 25, 2022 at 10:08 AM sp h <stackprogramer@gmail.com> wrote: > This is my image core yml file... > > On Wed, May 25, 2022 at 10:07 AM sp h <stackprogramer@gmail.com> wrote: > >> When I used this doc >> <https://kb.ettus.com/Getting_Started_with_RFNoC_in_UHD_4.0> and add the >> FFT block to the USRP x300 block not work correctly and send the command >> OOOOOO... >> For another original block, I had the same problem...How can solve my >> problem? >> Errors: >> gr::log :DEBUG: rfnoc_rx_streamer0 - Committing graph... >> [WARNING] [0/Radio#0] Attempting to set tick rate to 0.
