(Eclipse CDT+ GNU MCU Eclipse) is shaping up as an "Eclipse Embedded CDT"
https://projects.eclipse.org/projects/iot.embed-cdt
https://gnu-mcu-eclipse.github.io/debug/openocd/
Eclipse Team is planning to put together eclipse CDT and gnu mcu eclipse plugins as a single package so that it will be easy for IoT and Embedded developers - they can just download a single package and get started with IoT.
