Hi all, strugling really bad with programming my Teensy board. Went through all of this https://www.pjrc.com/teensy/troubleshoot.html 10 times. Tried different computers and USB cables. The issue persists.
Hardware
Software
When I first connected my Teensy the LED blink example was running fine (= LED blinking). Since I programmed it for the first time (with another simple example program) the board is in some sort of endless loop. Connecting and disconnecting all the time. Seems like with a lot of luck I managed to get the blink example back on it (=LED blinks again), but still it connects and disconnects all the time and I'm not able to work with it normally.
I also have a Teensy 3.1 which I can program just fine using my MacBook + the same cable.
I would be so glad about any sort of advice? What am I missing?
Hardware
- Teensy++ 2.0 (AT90USB1286)
- MacBook Pro (13 Inch, Mid 2009) or MacBook Pro (15 Inch, Late 2016)
Software
- Teensy Loader / Teensyduino 1.40
- Arduino IDE 1.8.5
