Zephyr Project on Beetle
Talkat Embedded Linux Conference + OpenIoT Summit North America 2017 · on Tuesday, 2017-02-21· at 15:00· Broadway I/II·
summary
Ported Zephyr to the ARM Beetle (256 KB flash, ~28 KB RAM plus 2 MB external) and compiles a Hello World image with GCC ARM on Ubuntu using the Zephyr SDK; basic port takes about a month. Demonstrates running microPython to blink an LED, poll a sonar and read a MAX-like sensor, and shows a custom driver built and working. Port includes board/SOC Kconfig, device tree/driver hooks, runtime NMI workaround for a watchdog, and automated sanitycheck tests and Gerrit-based contribution workflow.
