Quick, easy way to brick a NDLR - kbob - 02-27-2020
This morning I started a new Teensy project. Downloaded the latest Teensyduino, plugged in a Teensy 3.2, opened Blink, and hit the download button.
My NDLR was connected on another USB port. And you can guess what happened next -- I flashed Blink onto the NDLR.
So now I know there's a Teensy inside the NDLR, and I can see its amber LED blinking away.
I was able to reinstall the NDLR firmware easily enough; after all, I already had the Teensy loader open. So this story is a comedy, not a tragedy.

I'm glad you were able to figure that out without too much trouble.

That's the reason we love the Teensy platform, its virtually unbrickable with the dedicated firmware loader MCU. So far (knock on wood) we haven't had a unit brick yet.
By the way, you can probably identify the Teensy parts in this picture.
