This post walks through how to upload images from IoT devices to Golioth over CoAP using block upload. Once the image is at the server, Golioth Pipelines can route the data to the destination of your choice!
Embedded systems, like any software system, benefits from modularizing software components, especially as they approach production. In this talk at the Embedded Open Source Summit 2024, Golioth Firmware Lead Sam Friedman talks about how to create "microservices" for microcontrollers.
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.
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.
