Teensy tutorial not working

edit

Hi! I'm having problems with the Teensy tutorial. I've already worked through the linux tutorial with no problems.

Everything builds and loads properly, but when I start the ros2 serial agent, it appears to connect to the teensy and then crash out with no error messages. When this happens the teensy jumps into the error_loop and will just blink away forever.

I'm running Arduino 1.8.13, Teensyduino 1.53 and using a Teensy 4.1 board. I've used both the v2.0.2-foxy micro_ros_arduino release as well as v1.0.0 with the same results. I've also tried it with Arduino 1.8.15 and get the same results.

Here's the output from the micro ros agent terminal:
