One of my favorite things when working with Segger J-Link is RTT support which significalntly improves my debugging experience. With a single interface (one USB cable), I can run:

• RTT serial console to communicate with the target

• SystemView to capture system events

• gdb for general debugging

The latest addition to this list is real-time data streaming with the NuttX NxScope library and RTT channel as a communication interface. This feature is supported with nxscli tool since version 0.5.1. Now we can visualize and debug complex data relations much more simpler.

This post discusses how to configure the NxScope example with NuttX to work over an RTT channel with an RTT serial console and SystemView support.

For demonstration, we use Nordic nRF52832-DK board with a built-in J-Link OB interface, so there is no need to connect any external device.

PlotJuggler is a cool tool for visualizing time series data, supporting live data streaming. Since version 0.5.1, my nxscli tool has included support for data streaming over UDP port, which can be easily captured by PlotJuggler.

Let's see how to set up both tools and plot data from the NuttX NxScope library.
