Teensy 3.6 uploads intermittently

marks · Mar 16, 2020

Hi all,

I am trying to troubleshoot my way through an issue I'm having with my Teensy 3.6. As I was modifying some code, I randomly started getting this error when attempting to upload to the Teensy:

Code:

Arduino: 1.8.11 (Windows 10), TD: 1.51, Board: "Teensy 3.6, Keyboard + Mouse + Joystick, 180 MHz, Faster, US English"

Sketch uses 52728 bytes (5%) of program storage space. Maximum is 1048576 bytes.
Global variables use 20540 bytes (7%) of dynamic memory, leaving 241604 bytes for local variables. Maximum is 262144 bytes.

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

This happens almost every time I run the code, although it has not happened a few times, and it seems to be at random. I have attempted:

Changing the USB cable
Rebooting the Teensy
Rebooting my PC

The source code doesn't seem to matter, as it happens with every program. Here is the error with blink, for reference. This is also on Windows.

Edit: Forgot to mention that I get input from the Teensy from the Serial Monitor, so it is still communicating.

Thanks!

It looks like TeensyDuino is installed? If so it should be calling TeensyLoader/Teensy.exe to do the upload and not try to use AvrDude. Only a Teensy aware USB uploader like Teensy.exe will work to program a Teensy.

Is the small 'Teensy' program showing on the screen with window area showing 'Press Button on Teensy to manually enter Program Mode'. Do a Ctrl+R build and you should see the Teensy.exe and on the lowest line of the program it should show the name of the HEX file connected. Then Push the Button.

So I randomly got it working again and I'm not sure why. I'll update if I figure out what it was. Thanks for the reply!

Ive seen and had that error. It is a windows side issue.

Teensy 3.6 uploads intermittently
