Golioth will be at the inaugural Embedded World North America in Austin Texas, October 8th to 10th. Stop by the Joulescope booth (#1723) to see Golioth hardware, firmware, and cloud capabilities being monitored with a powerful (yet affordable) piece of test equipment.
Did you know that Zephyr doesn't have a plain old GPIO example? The closest thing is the blinky example that controls LEDs. Why is that? Zephyr expects you to write your own devicetree bindings. It's not that hard, and it's the topic of today's post.
WebAssembly runs on microcontrollers, but why would you want to do that? Dan Mangum shows us how to use Wasm with Zephyr RTOS, why you would want to, and he even discuss how to decide if the tradeoffs fit your needs.
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.
