Hi Wade, thank you very much for your answer. I have successfully debugged it. Can you also help me with my original problem? I am using the E320 and UHD 4.0 version. I want to save 2 ADC samples into block ram and read them later. For that reason, I have a trigger which starts the saving process. When I saved 2 ADC samples into block ram and read them later, I realized that some samples are zero. I debugged it and I saw that valid signals of ADCs are not always 1. They sometimes switch back to 0. While doing that, I have used the RFNoC-example as a starting point. I don't know what the real problem is, but I examined different examples and I realized that they used different files in their noc_shell files. For example, the gain example used chdr_to_axis_pyld_ctxt which generates payload and context data. But, ddc example used chdr_to_axis_data which generates only axis datas. Therefore; I have tried different files in noc_shell, but none of them worked as I expected. I don't want to take all the examples to the host or anywhere else. I just want all ADC samples to go into my custom RFNoC-block. I don't want any other datas such as metadatas or anything else, but only ADC samples.
My System: Device : E320 OS : Ubuntu 20.04.4 UHD: 4.0 Kind Regards, Yasir.
