+
+  The first time the body-post-estimation app is run, the .onnx file is converted to a
+  TRT engine file, which is a step than can take several minutes. Subsequent runs of the
+  body pose estimation app will skip the conversion and just load this engine file
+  directly. During the converstion, when high bandwidth is in use on the network (via
+  "--camera-mode=0"), the kernel stops delivering received UDP messages to the
+  application, resulting in no video being displayed. Later runs the same program, after
+  the conversion is complete, run as expected.

+   flashed with a FTDI cable.
