When it comes to automated testing, Zephyr's Native Simulator is worth your consideration. The next release of Zephyr will include offloaded sockets for Native Simulator, which means CI tests that complete many times faster than their native-hardware equivalents.

Golioth firmware engineer Mike Szczys walks through debugging the MCUboot bootloader using gdb. This is a slightly different task than normal Zephyr debugging, but can help to find tricky bugs.

Golioth will be joining our friends at Digikey on June 13th to talk about "Leveraging Zephyr to enable super-flexible IoT designs". 

Zephyr has built-in debugging for many of its supported boards. Here's a real-world example of utilizing the these tools to track down and fix a networking error with CoAP.

Manufacturing is marathon, not a sprint. Chris Gammell walks through five phases of IoT device production, discussing what's involved in each step and how Zephyr RTOS can help during his talk from the 2024 Embedded Open Source Summit.

Golioth Firmware Engineer Mike Szczys describes how we use GitHub Codespaces and Development (Dev) Containers to train engineers all over the world without any install required. Answering the question of how fast can a new Zephyr RTOS user go from zero to successful code compilation.

The RAK5010 is a cellular board based on Quectel's BG95 modem (Qualcomm chipset). A Nordic nRF52840 microcontroller "runs the show", connecting to the modem via UART. This is a nice combination for a number of applications like remote sensing, application tracking, and Bluetooth <> Cellular gateway. Let's walk through the process of developing for this board in the Zephyr RTOS.

In this post, we'll walk through a couple methods for defining abstract hardware interfaces in Zephyr using...
