I have an LED display that is driven by 3 Teensy 3.2 boards which are sealed away inside the case. It's possible to get at them, but kind of a pain. Normally not a problem, but I recently had a need to update the firmware with a small fix. To my dismay I found that the Serial Port selector in the Arduino IDE did nothing. Instead it seemed that the Teensy uploader continued to upload to a single Teensy. Is there any way to specify which board it uploads to (so that I can upload to each in turn) while all of them are connected? I'd even be fine with a simultaneous upload to all of them as the firmware is the same.
Thanks!
