    This sounds awesome! I just ordered a JLink debugger to test out the debug features.

    Is there a more detailed explanation of the debugging of the Teensy using platformio? Any user experiences?
    I expect that hardware modding (https://medium.com/@mattmatic/prepar...d-b014b0ce2999) of the teensy is still needed, right?

    Does that mean, that the automatic teensy rebooting and flashing is now working? This would be very helpful for my next project as
    I will use the Platformio Remote feature (which is really awesome btw) on a Raspberry Pi and several Teenys in an enclosed housing,
    without easy access.


    All in all great to see your love for the teensy as I use and advocate Platformio in every project.

    II'll post something here once I get my debugger in house and let you know how it goes. Thus far, the fine pitch soldering to the debug pins on the Teensy 3.2 is proving quite difficult. Hopefully switching to wire wrap will make it somewhat easier. I've also ordered a Teensy 3.6 which should be somewhat easier.
