    Trouble connecting Teensy 3.0 to OSX Mavericks

    Hi, I am new to this forum, coming from Arduino/MAXMSP/sound. Learning C++, but still using Arduino for many projects. I am very impressed by the work on the Teensy project, thank you so much for this!

    I have problems getting the Teensy 3.0 boards recognized by the OS. It doesn't show up in /dev as a tty.* and not in Arduino either. The same problems with all three boards, so it must be something I am not doing right.
    I have tried to communicate using Xcode and EmbedXcode+, without luck.
    When compiling the Arduino sketch or a Xcode project, a process called teensy_post_compile starts up and gets stuck at 90-95% CPU usage.
    I have to kill the teensy_post_compile process (after waiting 15 min...) just to be able to close Xcode. Arduino IDE doesn't crash, but is stuck at 90% compiling.

    I have a clean install of Arduino 1.0.5 and the latest Teensyduino. All other Arduino boards work fine, as well as my barebones and Attinies.
    My system is OSX 10.9.2 and the machine is a MacBook Pro 2.66 Intel Core 2 Duo with 8 GB RAM.

    Running the Teensy Loader works, that is, it recognises the boards.
    This is the verbose output from Teensy Loader:
    15:47:48: Teensy Loader 1.18, begin program
    15:47:48: File "Blink.hex". 1414 bytes, 1% used

    15:47:48: HID/macos: status: ok

    Thanks for any advice on this!

    Best regards,

    Hi,
    just got the new Teensy 3.1 and the audio shields and I am really eager to try them out. But my problem is exactly the same as before. No communication between Arduino and the Teensy. Please help. The teensy_post_compile gets stuck at 98-99% CPU and never ends, as the print screen shows:

    Here is the Verbose print from the Arduino console:

    Update from the North:
    I have now been sucsessful in connecting and downloading to Teensy w/ another mac, a completely clean macmini. When I saw how the connection was supposed to work, I tried to start the Teensy uploader manually on my laptop, before downloading the code with Arduino. That worked, meaning it sometimes downloads the code and reboots when I push the button. Sometimes, it starts a new instance of teensy_post_compile every time I hit the upload button and gets stuck at 98% CPU. Other times, nothing happens.
    It is very strange, I can't seem to find any pattern in the behaviour.
    Please help, has anybody else had similar issues?


    Best regards,


    Jørgen Larsson

    This is the first I've heard of it failing on a Mac in this way.

    The teensy_post_compile is supposed to run the Teensy Loader program, if it's not already running. Then it establishes a localhost network connection to Teensy Loader and send the name and directory where your freshly-compiled code is located. That's all it does. It doesn't actually do any USB communication (like the teensy_reboot program does).

    So I suppose the first question is whether it's getting hung up on the step where it tries to start Teensy Loader, or if it's having trouble making a localhost connection to Teensy Loader after it's already running?

    Perhaps a good test on the problematic machine would involve these steps?

    1: First, quit all programs and then reboot, so you're fresh. Make sure Mavricks didn't automatically run Arduino or Teensy Loader, so you're starting from a fresh reboot without any programs already running.

    2: Control-click on Arduino and use "show package contents". Navigate a couple folders in, until you find "hardware" and "tools" inside hardware. There you should see the Teensy Loader application. Run it, so Teensy Loader will be already running before you start Arduino.

    3: In Teensy Loader, use Help > Verbose Info.

    4: Run Arduino, open a sketch and click Verify. After Arduino compiles the code, it'll run teensy_post_compile.

    Perhaps something useful will show up in the verbose info window? It has a "Log" menu that lets you save to a text file, or you can copy-paste from that window to a message here.

    Another thing to check, which is a long-shot, would be special security software. I've never heard of such a problem on a Mac, but on Windows some overly-aggressive programs (like Zone Alarm) are sometimes mis-configured to interfere with localhost communication. Obviously an internet firewall shouldn't interfere with programs running locally on your own computer talking to each other with localhost-only networking that can't communicate to the internet, but it is a (rare) issue on Windows.

    Hi,
    thank you for the reply. I have now tested thoroughly and this is what I found:
    1. The first issue was that the Teensy Loader didn't find the file. The sketch needs to be saved before uploading.
    2. Teensy Loader must be manually started before Arduino.
    3. Three different scenarios are happening in no identifying (at least, to me...) order:
    a) Everything works, and Arduino returns with a happy "Done Uploading"
    b) The post compiler gets stuck, but the code gets uploaded if I push the reset button on the card.
    If I don't kill the post compiler manually, it will keep running and a new instance will start if I try a second upload.
    When I kill the post compiler, Arduino complains that it has lost contact with the Teensy Loader.
    c) The teensy_reboot gets stuck and the card does not reboot without a manual push on the button on the card.
    After that, two things can happen: Either the teensy_reboot quits, or I have to kill it.
    Either way, disconnecting/rebooting/clean installs/etc. does not seem to have any impact. After scenario b, scenario c can happen, or a. And it can work without any problem at least five times in a row, and then any of either b or c can occur. After I have to kill the reboot or the post compiler, it doesn't matter if I disconnect the card or not. Or restart the Loader or Arduino. It all seems like complete random.

    Below is a transcript of all three possible scenarios on my laptop.
