Hi Tellrell, Do not use the Xilinx SDK, only the Yocto one, i.e. /usr/local/share/uhd/images/y/sysroots/cortexa9t2hf-neon-oe-linux-gnueabi
You need to source the "environment-setup-cortexa9t2hf-neon-oe-linux-gnueabi" file before cross compiling. If you use cmake with building your application, you also need to set the flag "-DCMAKE_TOOLCHAIN_FILE=<path to UHD>/host/cmake/Toolchains/oe-sdk_cross.cmake". Also, if you just want to run the UHD example, it already exists on the N310's root file system at: /usr/lib/uhd/examples/rfnoc_replay_samples_from_file Jonathon On Tue, Aug 24, 2021 at 4:42 PM Tellrell White via USRP-users < usrp-users@lists.ettus.com> wrote: > I'm trying to compile the source code using SDK 2019.1.
