\ Hello,\ My application requires that I edit the RFDC applications, however, I am confused about how the UHD C++ API interfaces with the RFDC on the RFSoC.\ It appears when I make the RFNoC graph, the namespace x400_radio_control_impl is called, which starts the process of programming the RFDC as well as running Self Calibration. For reference, I instantiate my graph similar to the examples
\ `//Create RFNoC graph`\ `std::cout << std::endl;`\ `std::cout << "Creating the RFNoC graph with args: " << args << std::endl;`\ `auto graph = uhd::rfnoc::rfnoc_graph::make(args);`\ `…`\ `auto radio_rx_ctrl = graph->get_block<uhd::rfnoc::radio_control>(radio_rx_ctrl_id);` \ I have been able to trace up to rfnoc_graph.cpp, where once a graph is commited, it starts to create an object for each NoC. Following the RFNOC logs that print after the UHD 4.5 update, I found where the log “\[INFO\] \[0/Radio#0\] Calibrating channel 0” came from, which was found in x400_radio_control.cpp. So now, I am led to believe that whenever the radio block is instantiated, the RFDC properties get instantiated as well. \ After this part, is where my confusion starts…\ After following the logs which appear right before the RFNoC logs regarding calibration, specifically \ `[INFO] [MPM.PeriphManager.ClkMgr] Using Clock Configuration:`\ `DB0: Master Clock Rate: 491.52 MSps @Converter Rate 2.94912 GHz`\ `DB1: Master Clock Rate: 491.52 MSps @Converter Rate 2.94912 GHz` \ it seems there is a file x4xx_clock_mgr.py which supposedly sets the master clock rate and the converter rate, which is called by x4xx.py. x4xx.py also calls another function in x4xx_clock_policy.py, which seems to be the function of interest as it sets the properties on the RFDC, albeit hardcoded. The problem is I have not been able to trace how I get from x400_radio_control.cpp to x4xx.py. \ In short, am I correct that there is a trace between x400_radio_control.cpp and x4xx.py trace, and if so, where in the UHD C++ API does it call a python file, specifically the x4xx.py? \ Thanks\ Joe
