Riding the Upstream Wave: Keeping Your Zephyr Apps Regression Free

on YouTube ↗48m

" summary

Zephyr changes break users fast: unified kernel and a rewired IP stack force daily rebases and months of debugging (TCP was broken in early 1.6, fixed by 1.7). The project integrates mcuboot bootloader, nRF51 Bluetooth controller contributions (replacing Nordic softdevice), and 6LoWPAN over IPv6 to reach cloud services. Automation uses GitHub+LAVA CI to build across three Zephyr branches and multiple boards, deploy test firmware, and run console-parsed tests; CI catches regressions like the Zephyr 1.6→1.7 regression that made 5/6 updates fail. OTA uses Hawkbit OTA rollouts to push updates to six devices and validate rollback.
