Hey Nidhi, are you able to run the rfnoc_radio_loopback example? It skips the DmaFifo (which is not present in default bitfiles) but otherwise does the same. It documents all the common pitfalls of creating loopback apps (like calling enable_rx_timestamps(), and using back-edges).
Once that works, you can modify the code to match your needs. --M On Fri, Dec 6, 2024 at 1:27 PM Nidhi Panda <nidhi.pa...@cyronics.com> wrote: > *Dear USRP Support Team,* > Greetings of the day! > I am currently working with a *USRP N300 device with uhd 4.7 and gnu > radio v3.11.* I have created a simple loopback configuration in which > the data flows through the following blocks: > Rx_Radio > DDC > DMAFifo > DUC > Tx_Radio. > However, I am encountering an issue where *only the receiver is working*, > and the *transmitter is not starting*.
