    SmartMatrixSD card forces Teensy 3.1 loader to require press of Reset Button ?

    My SmartMatrixSD card forces Teensy 3.1 loader to require press of Reset Button for upload, regardless of the

    For example, I can compile BitmapTest fine, and upload it into a new Teensy 3.1 unattached to anything. No need to push reset button.
    This is the case even for simple aps like Blink.

    const int led = LED_BUILTIN;

    void setup() {
    pinMode(led, OUTPUT);
    }

    void loop() {
    digitalWrite(led, HIGH);
    delay(1000);
    digitalWrite(led, LOW);
    delay(1000);
    }


    When I do the same with the Teensy 3.1 that is soldered in the SmartMatrixSD card, it forces me to push reset button after each compile.
    When I do, each time I upload, the program uploads correctly and operates correctly.

    PixelMatrix asked for me to post this for your consideration.

    Running Arduino 1.05-r2 and Teensyduino 1.20-rc2.

    thanks,

    Don't know why but problem (which occurred through most of the day) self corrected.
    Today, upload did not require a button press.

    Strange but wonderful.
