Hello all, so recently I have been attempting to utilize this cool 60ghz transciever on the tx2 nvidia developer board with a brand new flashed image on it. I tried before as well witha modified image and thought that might be the issue. It was not. So far I am able to compile the program from source with the usb library from the tegra and the propietary library from the dongle vendor. It will compile without complaint on board but when I attempt to execute the executable it reports this below in the kernel.

I have attached the tar file for others to try what I am on my tx2. the executable with report command not found if no argument is given, but will cause segmentation fault when any acceptable argument is provided.
Any ideas?
