The Linux Foundation's Open Source Summit Europe comes to Prague this year, and a good part of it is embedded. The Embedded Linux Conference, the Zephyr Developer Summit, the PX4 Dev Summit, and a safety-critical software track all run inside the main summit.

Come a day early for the embedded side events on 6 October: the Yocto Project Developer Day, the Real-Time Linux User Forum, and the Zephyr Maintainers Forum, where maintainers and regular contributors set the project's direction for the coming year. Each needs its own registration.

[Spotflow](https://spotflow.io), where I work, will be there as part of the [Texas Instruments](https://www.ti.com/) booth, right in front of the keynote room, with a firmware observability demo. It is a battery-powered Bluetooth LE asset tracker built on TI's [CC2340R5](https://www.ti.com/product/CC2340R5), a Cortex-M0+ with 36 KB of RAM and no internet connection of its own. It runs Zephyr and sends its logs, metrics, and crash dumps out over Bluetooth through a nearby gateway.

The firmware has a memory bug left in on purpose. Shake the tracker and it crashes, and about ten seconds later the coredump is in the cloud, decoded down to the function and line. If you're attending, stop by the booth and ask for a walkthrough.
