Hello Everyone,
I have an X300 flashed to match the host UHD ver (4.2.0). I am trying to use
the command “get_rx_dboard_iface” to access GPIO pin settings….but I am
gettting error: **“Path not found in tree: /blocks/0/Radio#1/iface”**
If I go back to UHD ver 3.15.0 then the command runs successfully
Below is a simple code that fails on UHD v4.2.0 but works OK on v.3.15.0
\#============================================
\#include <uhd/utils/thread.hpp>
\#include <uhd/utils/safe_main.hpp>
\#include <uhd/usrp/multi_usrp.hpp>
\#include <uhd/exception.hpp>
\#include <uhd/types/tune_request.hpp>
\#include <boost/program_options.hpp>
\#include <boost/format.hpp>
\#include <boost/thread.hpp>
\#include <iostream>
int main()
{
// Initialize USRP receiver and Rx stream----------------------------------
uhd::usrp::multi_usrp::sptr usrp;
uhd::rx_streamer::sptr rxStream;
// Setup USRP x300s
uhd::device_addr_t devAddr;
devAddr\["addr0"\] = "192.168.130.2";
usrp = uhd::usrp::multi_usrp::make(devAddr);
// Setup channels
uhd::usrp::subdev_spec_t rxSpec("A:0 B:0");
usrp->set_rx_subdev_spec(rxSpec);
//Get dBoard info:
uhd::usrp::dboard_iface::sptr dBoard;
dBoard = usrp->get_rx_dboard_iface(0); // < ——- FAILS here
#std::cout << dBoard << std::endl;
return EXIT_SUCCESS;
}
