Segger embedded studio serializer how to#
Refer to the documentation of your Linux distribution for information on how to download and install it. If the command does not provide output, you must install the make tool. You must install a set of tools to complete the environment setup process.įirst, make sure that you have the make tool installed on your system. If you want to use the logger module, you must utilize the RTT backend or a UART instance other than UART0. OpenThread API can be used to access the hardware random number generator.

USB=1 parameter is optional and enables USB CDC support for serial communication. The command line interface is intended to be executed by a script so the init params and result params are specified in Python.Make -f examples/Makefile-nrf52840 COMMISSIONER=1 JOINER=1 COAP=1 DNS_CLIENT=1 MTD_NETDIAG=1 BORDER_ROUTER=1 MAC_FILTER=1 TMF_PROXY=1 USB=1 If not, there is a Keil tutorial here or you can take a look at my Makefile if you are using GCC. UsageĭISCLAIMER: I have only ever used the Python stack on a Linux machine using Python v2.7.Īdding the Lys C library to an existing project is easy if you already have RTT working.

There is a post regarding my Makefiles here. I use GCC so it was really easy to add support for compiling and downloading the embedded device's firmware using Make. lcli.py - The Lys Command Line InterfaceĪll of the Python classes are part of a package so they should be kept together in a folder named 'lys'.maker.py - A simple wrapper for invoking Make.lys.py - Encodes and decodes Lys messages.rtt.py - A TCP socket in its own thread with a queue-based interface.The Python stack is a little more involved but the individual pieces are pretty simple:

Here is a simple example of how Lys can be used to parameterize the classic blinky example. The C library only requires stdbool.h, stdint.h, string.h, and SEGGER_RTT.h and has the usual structure: Python's struct class is really useful in situations like this one.

I decided to be pedantic about the C data types on the PC side in order to avoid surprises. Take a look at the header file for more details. It always starts by printing a useful blurb like this one when a new connection is accepted: The RTT socket is accessable via TCP at 127.0.0.1:19021. However, I couldn't get pynrfjprog's RTT functionality to work when multiple debuggers were opened concurrently so I decided to roll my own socket class with the hope that I could use it to ping-pong between multiple RTT connections in the future. In fact, the RTT socket can be read directly from pynrfjprog using friendly functions like rtt_start and rtt_read.

Upon further experimentation I confirmed that connecting to a J-Link debugger with pynrfjprog causes the J-Link driver to automatically make the RTT socket available until pynrjprog disconnects from the debugger. I knew that I could use pynrfjprog to enumerate the J-Link debuggers that are currently plugged into the PC, select one of the debuggers by serial number, and then use the debugger to reset the device. Python is my favorite desktop programming language so, naturally, pynrfjprog is my preferred tool for interacting with a J-Link debugger.

Furthermore, RTT works with all J-Link devices and it's pretty easy to work with from the PC because the interface is just a socket. SEGGER's RTT functionality is even better because it acts like a serial port but doesn't tie up the device's UART peripheral. BackgroundĪ serial port is the obvious choice for passing data between a PC and an embedded device. The firmware only needs to be compiled and downloaded once so step zero is optional. Allow the device to report a result if it has finished.Allow the device to send log messages back to the PC while it's running.Allow the device to run for some arbitrary amount of time or until it finishes.Send some parameters from the PC to the device.Lys is a serialization protocol for synchronization and data exchange between a PC and an embedded device.
