cross-posting my stack exchange question here for visibility. In summary I’m having issues running the Zephyr host emulator tutorial. All the things appear to compile and run correctly, except the Zephyr app aborts stating a “Failed status”. Any help would be appreciated!
Yikes, found the problem shortly after posting. Turns out I wasn’t following directions and actually had to modify firmware/zephyr_apps/microros_extensions/microros_transports.h as stated. Changing that to the correct IP (127.0.0.1 in my case) fixed the problem. More details here https://robotics.stackexchange.com/a/107362/37930
