Hi,
I followed the instructions on a Linux machine running GNURadio 3.7 and it worked exactly as described.
I then ran the tutorial on an NVIDIA Xavier Linux machine w/ GNURadio 3.8 and all the steps seemed to work. The QA test worked in python, and `cmake; make; sudo make install; sudo ldconfig` all ran without any errors. However, when I open GRC, I cannot see the block.
I am wondering if this tutorial is not up-to-date w/ GNURadio 3.8 or if maybe there is something weird about the Xavier that is causing the bug.
Let me know,
Thanks!
