Hi Michael, Please see this app note which covers cross compiling UHD/GR/gr-ettus.
You can treat your OOT the same as gr-ettus. https://kb.ettus.com/Software_Development_on_the_E3xx_USRP_-_Building_RFNoC_UHD_/_GNU_Radio_/_gr-ettus_from_Source#SDK_Setup https://kb.ettus.com/Software_Development_on_the_E3xx_USRP_-_Building_RFNoC_UHD_/_GNU_Radio_/_gr-ettus_from_Source#Cross-Compiling_gr-ettus Regards, Nate Temple On Mon, Nov 25, 2019 at 3:09 PM Michael Bassi via USRP-users < usrp-users@lists.ettus.com> wrote: > Hi all, > > > I have created my first GNU Radio Out of Tree (OOT) module in C++ > I have tested it in GNU Radio Companion (GRC) and it works as expected. > I would now like to run it from my USRP device (E312). > Currently my USRP does not recognize my custom module.
